Mobile native client via Flutter (#426)

* feat: mobile support. Basic functionality development includes adding and deleting transactions,viewing balances, * Fix mobile support issues in PR #426 This commit addresses the critical issues identified in the mobile-support PR: 1. **GitHub Actions Workflow Path Issues (Critical)** - Add mobile/ prefix to all path filters in flutter-build.yml - Add working-directory to all Flutter commands - Fix Android keystore and iOS CocoaPods paths - Fix artifact upload paths 2. **Error Handling Improvements** - Add try-catch blocks to all HTTP requests in services - Wrap all JSON parsing operations in error handling - Add proper error messages for network failures 3. **HTTP Request Timeout Configuration** - Add 30-second timeout to all HTTP requests - Prevents hanging on network failures 4. **Defensive Null Checks in Providers** - Add containsKey() checks before accessing result maps - Add proper type casting with null safety - Add fallback error messages These changes ensure the workflow triggers correctly on mobile/ directory changes and improves overall code robustness. * Fix transactions exposure and error handling issues - Add UnmodifiableListView to transactions getter to prevent external mutation - Call notifyListeners() immediately after setting _isLoading = false - Move jsonDecode to run only after successful statusCode verification - Replace string concatenation with Uri.replace() for proper URL encoding - Add try/catch for jsonDecode on non-2xx responses to handle non-JSON errors * Fix exception handling and duplicate parsing in auth_service.dart - Replace broad catch-all exception handlers with targeted exception handling - Add specific catches for SocketException, TimeoutException, HttpException, FormatException, and TypeError - Return safe, user-friendly error messages instead of exposing internal details - Log full exception details and stack traces using debugPrint for debugging - Fix duplicate User.fromJson calls in login and signup methods by parsing once and reusing the instance - Improve code efficiency and security by preventing information leakage * Fix 2FA login crash and improve UX Fixed the crash that occurred when logging in with 2FA-enabled accounts and improved the user experience by not showing error messages when MFA is required (it's a normal flow, not an error). Changes: - Added mounted check before setState() in login screen - Modified AuthProvider to not set error message when MFA is required - Ensures smooth transition from password entry to OTP entry - Prevents "setState() called after dispose()" error The flow now works correctly: 1. User enters email/password → clicks Sign In 2. Backend responds with mfa_required 3. OTP input field appears with friendly blue prompt (no red error) 4. User enters 6-digit code → clicks Sign In again 5. Login succeeds * Add debug logs to trace 2FA login flow Added comprehensive debug logging to understand why OTP field is not showing when MFA is required: - Log backend response status and body - Log login result in AuthProvider - Log MFA required state - Log when OTP field should be shown This will help identify if the issue is: 1. Backend not returning mfa_required flag 2. Response parsing issue 3. State management issue 4. UI rendering issue * Fix 2FA login flow by moving MFA state to AuthProvider PROBLEM: The LoginScreen was being recreated when AuthProvider called notifyListeners(), causing all internal state (_showOtpField) to be lost. This resulted in the OTP input field never appearing, making 2FA login impossible. ROOT CAUSE: The AppWrapper uses a Consumer<AuthProvider> that rebuilds the entire widget tree when auth state changes. When login() sets isLoading=false and calls notifyListeners(), a brand new LoginScreen instance is created, resetting all internal state. SOLUTION: - Moved _showMfaInput state from LoginScreen to AuthProvider - AuthProvider now manages when to show the MFA input field - LoginScreen uses Consumer to read this state reactively - State survives widget rebuilds FLOW: 1. User enters email/password → clicks Sign In 2. Backend responds with mfa_required: true 3. AuthProvider sets _showMfaInput = true 4. Consumer rebuilds, showing OTP field (state preserved) 5. User enters code → clicks Sign In 6. Backend validates → returns tokens → login succeeds Backend is confirmed working via tests (auth_controller_test.rb). * Fix mobile 2FA login requiring double password entry Problem: When 2FA is required during mobile login, the LoginScreen was being destroyed and recreated, causing text controllers to reset and forcing users to re-enter their credentials. Root cause: AppWrapper was checking authProvider.isLoading and showing a full-screen loading indicator during login attempts. This caused LoginScreen to be unmounted when isLoading=true, destroying the State and text controllers. When the backend returned mfa_required, isLoading=false triggered recreation of LoginScreen with empty fields. Solution: - Add isInitializing state to AuthProvider to distinguish initial auth check from active login attempts - Update AppWrapper to only show loading spinner during isInitializing, not during login flow - LoginScreen now persists across login attempts, preserving entered credentials Flow after fix: 1. User enters email/password 2. LoginScreen stays mounted (shows loading in button only) 3. Backend returns mfa_required 4. MFA field appears, email/password fields retain values 5. User enters OTP and submits (email/password automatically included) Files changed: - mobile/lib/providers/auth_provider.dart: Add isInitializing state - mobile/lib/main.dart: Use isInitializing instead of isLoading in AppWrapper * Add OTP error feedback for mobile 2FA login When users enter an incorrect OTP code during 2FA login, the app now: - Displays an error message indicating the code was invalid - Keeps the MFA input field visible for retry - Automatically clears the OTP field for easy re-entry Changes: - mobile/lib/providers/auth_provider.dart: * Distinguish between first MFA request vs invalid OTP error * Show error message when OTP code was submitted but invalid * Keep MFA input visible when in MFA flow with errors - mobile/lib/screens/login_screen.dart: * Clear OTP field after failed login attempt * Improve UX by allowing easy retry without re-entering credentials User flow after fix: 1. User enters email/password 2. MFA required - OTP field appears 3. User enters wrong OTP 4. Error message shows "Two-factor authentication required" 5. OTP field clears, ready for new code 6. User can immediately retry without re-entering email/password * Improve OTP error message clarity When user enters an invalid OTP code, show clearer error message "Invalid authentication code. Please try again." instead of the confusing "Two-factor authentication required" from backend. This makes it clear that the OTP was wrong, not that they need to start the 2FA process. * chore: delete generation ai create test flow md. * Update mobile/lib/screens/login_screen.dart Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> Signed-off-by: Lazy Bone <89256478+dwvwdv@users.noreply.github.com> * feat: add pubspec.lock file. * Linter * Update mobile/android/app/build.gradle Co-authored-by: Pedro Piñera Buendía <663605+pepicrft@users.noreply.github.com> Signed-off-by: Lazy Bone <89256478+dwvwdv@users.noreply.github.com> * Update mobile/android/app/build.gradle com.sure.mobile -> am.sure.mobile Co-authored-by: Pedro Piñera Buendía <663605+pepicrft@users.noreply.github.com> Signed-off-by: Lazy Bone <89256478+dwvwdv@users.noreply.github.com> * Update mobile/ios/Runner.xcodeproj/project.pbxproj Co-authored-by: Pedro Piñera Buendía <663605+pepicrft@users.noreply.github.com> Signed-off-by: Lazy Bone <89256478+dwvwdv@users.noreply.github.com> * Update mobile/ios/Runner.xcodeproj/project.pbxproj Co-authored-by: Pedro Piñera Buendía <663605+pepicrft@users.noreply.github.com> Signed-off-by: Lazy Bone <89256478+dwvwdv@users.noreply.github.com> * Update mobile/ios/Runner.xcodeproj/project.pbxproj Co-authored-by: Pedro Piñera Buendía <663605+pepicrft@users.noreply.github.com> Signed-off-by: Lazy Bone <89256478+dwvwdv@users.noreply.github.com> * Fix iOS deployment target and update documentation - Update iOS minimum deployment target from 12.0 to 13.0 in Podfile for Flutter compatibility - Translate SIGNING_SETUP.md from Chinese to English for better accessibility - Remove TECHNICAL_GUIDE.md as requested * Restore TECHNICAL_GUIDE.md with partial content removal - Restore mobile/docs/TECHNICAL_GUIDE.md (previously deleted) - Remove only License, Contributing, and Related Links sections (from line 445 onwards) - Keep all technical documentation content (lines 1-444) * Fix setState after dispose errors across mobile app This commit fixes 5 critical setState/dispose errors identified by Cursor: 1. backend_config_screen.dart: Add mounted checks in _testConnection() and _saveAndContinue() methods to prevent setState calls after async operations (http.get, SharedPreferences) when widget is disposed. 2. transaction_form_screen.dart: Add mounted check in _selectDate() after showDatePicker to prevent setState when modal is dismissed while date picker is open. 3. main.dart: Add mounted check in _checkBackendConfig() after ApiConfig.initialize() to handle disposal during async initialization. 4. transactions_list_screen.dart: Add mounted check in the .then() callback of _showAddTransactionForm() to prevent calling _loadTransactions() on a disposed widget when modal is closed. 5. transactions_provider.dart: Fix premature notifyListeners() by removing intermediate notification after _isLoading = false, ensuring listeners only get notified once with complete state updates to prevent momentary stale UI state. All setState calls after async operations now properly check mounted status to prevent "setState() called after dispose()" errors. * Fix Android build: Remove package attribute from AndroidManifest.xml Remove deprecated package attribute from AndroidManifest.xml. The namespace is now correctly defined only in build.gradle as required by newer versions of Android Gradle Plugin. This fixes the build error: "Incorrect package="com.sure.mobile" found in source AndroidManifest.xml. Setting the namespace via the package attribute in the source AndroidManifest.xml is no longer supported." * Update issue templates * Change package name from com.sure.mobile to am.sure.mobile Updated Android package name across all files: - build.gradle: namespace and applicationId - MainActivity.kt: package declaration and file path - Moved MainActivity.kt from com/sure/mobile to am/sure/mobile This aligns with the package name change made in the mobile-support branch and fixes app crashes caused by package name mismatch. * Fix mobile app code quality issues - Add mounted check in backend_config_screen.dart to prevent setState after dispose - Translate Chinese comments to English in transactions_list_screen.dart for better maintainability - Replace brittle string-split date conversion with DateFormat in transaction_form_screen.dart for safer date handling These changes address code review feedback and improve code robustness. * Remove feature request template Delete unused feature request issue template file. * Fix mobile app code quality issues - Fix URL construction in backend_config_screen.dart to prevent double slashes by normalizing base URL (removing trailing slashes) before appending paths - Update pubspec.yaml to require Flutter 3.27.0+ for withValues API compatibility - Improve amount parsing robustness in transactions_list_screen.dart with proper locale handling, sign detection, and fallback error handling - Fix dismissible delete handler to prevent UI/backend inconsistency by moving deletion to confirmDismiss and only allowing dismissal on success * Fix mobile app performance and security issues - Eliminate duplicate _getAmountDisplayInfo calls in transactions list by computing display info once per transaction item - Upgrade flutter_secure_storage from 9.0.0 to 10.0.0 for AES-GCM encryption - Update dev dependencies: flutter_lints to 6.0.0 and flutter_launcher_icons to 0.14.4 * Update Android SDK requirements for flutter_secure_storage v10 - Increase compileSdk from 35 to 36 - Increase minSdkVersion from 21 to 24 This is required by flutter_secure_storage v10+ which uses newer Android APIs for AES-GCM encryption. * Fix transaction deletion message not displaying properly The success message was being shown in the onDismissed callback, which executes after the dismissal animation completes. By that time, the context may have become invalid due to widget tree rebuilds, causing the SnackBar to not display. Moved the success message to the confirmDismiss callback where we already have a captured scaffoldMessenger reference, ensuring the message displays reliably before the dismissal animation begins. * Add mounted check before showing SnackBar after async operation * Update mobile/android/app/build.gradle Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> Signed-off-by: Lazy Bone <89256478+dwvwdv@users.noreply.github.com> * Fix empty state refresh and auth error feedback in mobile transactions screen - Wrap empty state in RefreshIndicator with CustomScrollView to enable pull-to-refresh when no transactions exist - Wrap error state in RefreshIndicator as well for consistency - Add SnackBar feedback when auth token is null in _loadTransactions instead of silent failure - Ensure mounted check before showing SnackBar to prevent errors after widget disposal * Fix flash of 'No accounts yet' page on app startup Added initialization state tracking to AccountsProvider to prevent the empty state from briefly showing while accounts are being loaded for the first time. Changes: - Add _isInitializing flag to AccountsProvider (starts as true) - Set to false after first fetchAccounts() completes - Reset to true when clearAccounts() is called - Update DashboardScreen to show loading during initialization This ensures a smooth user experience without visual flashing on app launch. * Refactor: Extract transaction deletion logic into dedicated method Improved code readability by extracting the 67-line confirmDismiss callback into a separate _confirmAndDeleteTransaction method. Changes: - Add Transaction model import - Create _confirmAndDeleteTransaction method that handles: - Confirmation dialog - Token retrieval - Deletion API call - Success/failure feedback - Simplify confirmDismiss to single line calling new method This separation of concerns makes the code more maintainable and the Dismissible widget configuration more concise. * Enhance Flutter build workflow with keystore checks Signed-off-by: Lazy Bone <89256478+dwvwdv@users.noreply.github.com> * Implement conditional signing configuration Added a check for keystore properties before configuring signing.

+# Sure Mobile
+
+A Flutter mobile application for [Sure](https://github.com/we-promise/sure) personal finance management system. This is the mobile client that connects to the Sure backend server.
+
+## About
+
+This app is a mobile companion to the [Sure personal finance management system](https://github.com/we-promise/sure). It provides basic functionality to:
+
+- **Login** - Authenticate with your Sure Finance server
+- **View Balance** - See all your accounts and their balances
+
+For more detailed technical documentation, see [docs/TECHNICAL_GUIDE.md](docs/TECHNICAL_GUIDE.md).
+
+## Features
+
+- 🔐 Secure authentication with OAuth 2.0
+- 📱 Cross-platform support (Android & iOS)
+- 💰 View all linked accounts
+- 🎨 Material Design 3 with light/dark theme support
+- 🔄 Token refresh for persistent sessions
+- 🔒 Two-factor authentication (MFA) support
+
+## Requirements
+
+- Flutter SDK >= 3.0.0
+- Dart SDK >= 3.0.0
+- Android SDK (for Android builds)
+- Xcode (for iOS builds)
+
+## Getting Started
+
+### 1. Install Flutter
+
+Follow the official Flutter installation guide: https://docs.flutter.dev/get-started/install
+
+### 2. Install Dependencies
+
+```bash
+flutter pub get
+
+# For iOS development, also install CocoaPods dependencies
+cd ios
+pod install
+cd ..
+```
+
+### 3. Generate App Icons
+
+```bash
+flutter pub run flutter_launcher_icons
+```
+
+This step generates the app icons for all platforms based on the source icon in `assets/icon/app_icon.png`. This is required before building the app locally.
+
+### 4. Configure API Endpoint
+
+Edit `lib/services/api_config.dart` to point to your Sure Finance server:
+
+```dart
+// For local development with Android emulator
+static String _baseUrl = 'http://10.0.2.2:3000';
+
+// For local development with iOS simulator
+static String _baseUrl = 'http://localhost:3000';
+
+// For production
+static String _baseUrl = 'https://your-sure-server.com';
+```
+
+### 5. Run the App
+
+```bash
+# For Android
+flutter run -d android
+
+# For iOS
+flutter run -d ios
+
+# For web (development only)
+flutter run -d chrome
+```

+### Transactions
+- `GET /api/v1/transactions` - Get all transactions (optionally filter by `account_id` query parameter)
+- `POST /api/v1/transactions` - Create a new transaction
+- `PUT /api/v1/transactions/:id` - Update an existing transaction
+- `DELETE /api/v1/transactions/:id` - Delete a transaction
+
+#### Transaction POST Request Format
+```json
+{
+  "transaction": {
+    "account_id": "2980ffb0-f595-4572-be0e-7b9b9c53949b",  // required
+    "name": "test",  // required
+    "date": "2025-07-15",  // required
+    "amount": 100,  // optional, defaults to 0
+    "currency": "AUD",  // optional, defaults to your profile currency
+    "nature": "expense"  // optional, defaults to "expense", other option is "income"
+  }
+}
+```
+
+## CI/CD
+
+The app includes automated CI/CD via GitHub Actions (`.github/workflows/flutter-build.yml`):
+
+- **Triggers**: On push/PR to `main` branch when Flutter files change
+- **Android Build**: Generates release APK and AAB artifacts
+- **iOS Build**: Generates iOS release build (unsigned)
+- **Quality Checks**: Code analysis and tests run before building
+
+### Downloading Build Artifacts
+
+After a successful CI run, download artifacts from the GitHub Actions workflow:
+- `app-release-apk` - Android APK file
+- `app-release-aab` - Android App Bundle (for Play Store)
+- `ios-build-unsigned` - iOS app bundle (unsigned, see [iOS build guide](docs/iOS_BUILD.md) for signing)
+
+## Building for Release
+
+### Android
+
+```bash
+flutter build apk --release
+# or for App Bundle
+flutter build appbundle --release
+```
+
+### iOS
+
+```bash
+# Ensure CocoaPods dependencies are installed first
+cd ios && pod install && cd ..
+
+# Build iOS release
+flutter build ios --release
+```
+
+For detailed iOS build instructions, troubleshooting, and CI/CD setup, see [docs/iOS_BUILD.md](docs/iOS_BUILD.md).
+
+## Future Expansion
+
+This app provides a foundation for additional features:
+
+- Transaction history
+- Account sync
+- Budget management
+- Investment tracking
+- AI chat assistant
+- Push notifications
+- Biometric authentication

+# Android Signing Setup Guide
+
+## GitHub Secrets Configuration
+
+To enable CI/CD automatic signing of APK/AAB files, you need to configure the following Secrets in your GitHub repository:
+
+### Step 1: Get Keystore Base64 Encoding
+
+The base64 encoding of your keystore has been generated in the `keystore-base64.txt` file in the project root directory.
+
+View the content:
+```bash
+cat keystore-base64.txt
+```
+
+### Step 2: Add Secrets on GitHub
+
+Navigate to your GitHub repository:
+1. Click on **Settings**
+2. In the left menu, click on **Secrets and variables** > **Actions**
+3. Click the **New repository secret** button
+4. Add the following four secrets:
+
+| Secret Name | Value |
+|------------|-----|
+| `KEYSTORE_BASE64` | The base64 string copied from `keystore-base64.txt` |
+| `KEY_STORE_PASSWORD` | Your keystore password |
+| `KEY_PASSWORD` | Your key password |
+| `KEY_ALIAS` | Your key alias |
+
+### Step 3: Verify Setup
+
+After completing the setup, push code to the main branch or create a Pull Request. The CI/CD will automatically:
+1. Run tests
+2. Build signed APK
+3. Build signed AAB
+4. Upload build artifacts to GitHub Actions artifacts
+
+## Local Build
+
+Local build is already configured, with signing information in the `android/key.properties` file.
+
+Build signed versions locally:
+```bash
+flutter build apk --release
+flutter build appbundle --release
+```
+
+## Security Notes
+
+- ✅ `key.properties` and keystore files have been added to `.gitignore`
+- ✅ These files will not be committed to the Git repository
+- ✅ CI/CD uses GitHub Secrets to securely store signing information
+- ⚠️ Please keep the `keystore-base64.txt` file safe; you can delete it after setting up GitHub Secrets
+
+## Keystore Information
+
+- **File Location**: `android/app/upload-keystore.jks`
+- **Validity**: 10,000 days
+
+⚠️ **Important Notice**:
+- Please keep your keystore password, key password, and alias safe
+- This information is only stored locally in the `android/key.properties` file (added to .gitignore)
+- GitHub Secrets also need to be configured with this information
+- Be sure to back up your keystore file - losing it will prevent you from updating published applications!

+# Sure Mobile - Technical Documentation
+
+## Project Overview
+
+Sure Mobile is the mobile application for the [Sure Personal Finance Management System](https://github.com/we-promise/sure), developed with Flutter framework and supporting both Android and iOS platforms. This application provides core mobile functionality for the Sure finance management system, allowing users to view and manage their financial accounts anytime, anywhere.
+
+### Backend Relationship
+
+This application is a client app for the Sure Finance Management System and requires connection to the Sure backend server (Rails API) to function properly. Backend project: https://github.com/we-promise/sure
+
+## Core Features
+
+### 1. Backend Configuration
+- **Server Address Configuration**: Configure Sure backend server URL on first launch
+- **Connection Testing**: Provides connection test functionality to verify server availability
+- **Address Persistence**: Server address is saved locally and automatically loaded on next startup
+
+### 2. User Authentication
+- **Login**: Support email and password login
+- **Two-Factor Authentication (MFA)**: Support OTP verification code secondary verification
+- **User Registration**: Support new user registration (backend supported)
+- **Token Management**:
+  - Access Token for API request authentication
+  - Refresh Token for refreshing expired Access Tokens
+  - Tokens securely stored in device's secure storage
+- **Auto-login**: Automatically checks local tokens on app startup and logs in if valid
+- **Device Information Tracking**: Records device information on login for backend session management
+
+### 3. Account Management
+- **Account List Display**: Shows all user financial accounts
+- **Account Classification**:
+  - **Asset Accounts**: Bank accounts, investment accounts, cryptocurrency, real estate, vehicles, etc.
+  - **Liability Accounts**: Credit cards, loans, etc.
+  - **Other Accounts**: Uncategorized accounts
+- **Account Type Support**:
+  - Depository
+  - Credit Card
+  - Investment
+  - Loan
+  - Property
+  - Vehicle
+  - Crypto
+  - Other assets/liabilities
+- **Balance Display**: Shows current balance and currency type for each account
+- **Pull to Refresh**: Supports pull-to-refresh for account data
+
+## Technical Architecture
+
+### Tech Stack
+- **Framework**: Flutter 3.0+
+- **Language**: Dart 3.0+
+- **State Management**: Provider
+- **Network Requests**: http
+- **Local Storage**:
+  - shared_preferences (non-sensitive data, like server URL)
+  - flutter_secure_storage (sensitive data, like tokens)

+```
+
+### Account Data Flow
+
+#### 1. Fetch Account List (dashboard_screen.dart)
+
+```
+Enter dashboard
+    ↓
+_loadAccounts()
+    ↓
+Get valid Access Token from AuthProvider
+    ├─ Token invalid
+    │   ↓
+    │  Logout and return to login screen
+    │
+    └─ Token valid
+        ↓
+       AccountsProvider.fetchAccounts()
+        ↓
+       Call AccountsService.getAccounts()
+        ↓
+       Send GET /api/v1/accounts
+        ├─ Success (200)
+        │   ↓
+        │  Parse account data
+        │   ↓
+        │  Group by classification (asset/liability)
+        │   ↓

+#### 2. Account Classification Logic (accounts_provider.dart)
+
+```dart
+// Asset accounts: classification == 'asset'
+List<Account> get assetAccounts =>
+    accounts.where((a) => a.isAsset).toList();
+
+// Liability accounts: classification == 'liability'
+List<Account> get liabilityAccounts =>
+    accounts.where((a) => a.isLiability).toList();
+
+// Uncategorized accounts
+List<Account> get uncategorizedAccounts =>
+    accounts.where((a) => !a.isAsset && !a.isLiability).toList();
+```
+
+### UI State Management
+
+The app uses Provider for state management, with two main providers:
+
+#### AuthProvider (auth_provider.dart)
+Manages authentication-related state:
+- `isAuthenticated`: Whether user is logged in
+- `isLoading`: Whether loading is in progress
+- `user`: Current user information
+- `errorMessage`: Error message
+- `mfaRequired`: Whether MFA verification is required
+
+#### AccountsProvider (accounts_provider.dart)
+Manages account data state:
+- `accounts`: All accounts list
+- `isLoading`: Whether loading is in progress
+- `errorMessage`: Error message
+- `assetAccounts`: Asset accounts list
+- `liabilityAccounts`: Liability accounts list
+
+## API Endpoints
+
+The app interacts with the backend through the following API endpoints:
+
+### Authentication
+- `POST /api/v1/auth/login` - User login
+- `POST /api/v1/auth/signup` - User registration
+- `POST /api/v1/auth/refresh` - Refresh token
+
+### Accounts
+- `GET /api/v1/accounts` - Get account list (supports pagination)
+
+### Health Check
+- `GET /sessions/new` - Verify backend service availability
+
+## Data Models
+
+### Account Model
+```dart
+class Account {
+  final String id;              // Account ID (UUID)
+  final String name;            // Account name
+  final String balance;         // Balance (string format)
+  final String currency;        // Currency type (e.g., USD, TWD)
+  final String? classification; // Classification (asset/liability)
+  final String accountType;     // Account type (depository, credit_card, etc.)
+}
+```
+
+### AuthTokens Model
+```dart
+class AuthTokens {
+  final String accessToken;     // Access token
+  final String refreshToken;    // Refresh token
+  final int expiresIn;          // Expiration time (seconds)
+  final DateTime expiresAt;     // Expiration timestamp
+}
+```
+
+### User Model
+```dart
+class User {
+  final String id;              // User ID (UUID)
+  final String email;           // Email
+  final String firstName;       // First name
+  final String lastName;        // Last name
+}
+```
+
+## Security Mechanisms
+
+### 1. Secure Token Storage
+- Uses `flutter_secure_storage` for encrypted token storage
+- Tokens are never saved in plain text in regular storage
+- Sensitive data is automatically cleared when app is uninstalled
+
+### 2. Token Expiration Handling
+- Access Token is automatically refreshed using Refresh Token after expiration
+- Requires re-login when Refresh Token is invalid
+- All API requests check token validity
+
+### 3. Device Tracking
+- Records device information on each login (device ID, model, OS)
+- Backend can manage user sessions based on device information
+
+### 4. HTTPS Support
+- Production environment enforces HTTPS
+- Development environment supports HTTP (local testing only)
+
+## Theme & UI
+
+### Material Design 3
+The app follows Material Design 3 specifications:
+- Dynamic color scheme (based on seed color #6366F1)
+- Rounded cards (12px border radius)
+- Responsive layout
+- Dark mode support (follows system)
+
+### Responsive Design
+- Pull-to-refresh support
+- Loading state indicators
+- Error state display
+- Empty state prompts
+
+## Development & Debugging
+

+# iOS Build Guide
+
+## Issue Diagnosis: module 'flutter_secure_storage' not found
+
+### Root Cause
+This error occurs because CocoaPods dependencies have not been installed. `flutter_secure_storage` is a Flutter plugin that requires native platform support, and its iOS native code must be installed via CocoaPods.
+
+### Solution
+
+#### First-time Setup or After Dependency Updates
+```bash
+# 1. Get Flutter dependencies
+flutter pub get
+
+# 2. Navigate to iOS directory and install CocoaPods dependencies
+cd ios
+pod install
+cd ..
+```
+
+#### Clean Build (if encountering issues)
+```bash
+# Clean Flutter build cache
+flutter clean
+
+# Re-fetch dependencies
+flutter pub get
+
+# Clean and reinstall Pods
+cd ios
+rm -rf Pods Podfile.lock
+pod install
+cd ..
+```
+
+## Local Building
+
+### Method 1: Using Flutter CLI
+```bash
+# Debug mode
+flutter build ios --debug
+
+# Release mode (requires Apple Developer certificate)
+flutter build ios --release
+
+# Release mode (no code signing, for build testing only)
+flutter build ios --release --no-codesign
+```
+
+### Method 2: Using Xcode
+1. Ensure you have run `pod install`
+2. Open `ios/Runner.xcworkspace` (**Note: NOT .xcodeproj**)
+3. Select target device or simulator
+4. Click Run button or press Cmd+R
+
+## CI/CD Automated Builds
+
+### GitHub Actions Workflow
+
+The project is configured with automated iOS build process, triggered by:
+- Push to `main` branch
+- Pull Requests
+- Manual trigger (workflow_dispatch)
+
+#### Build Steps
+1. **Environment Setup**: macOS runner + Flutter 3.32.4
+2. **Dependency Installation**: `flutter pub get` + `pod install`
+3. **Code Analysis**: `flutter analyze`
+4. **Test Execution**: `flutter test`
+5. **iOS Build**: `flutter build ios --release --no-codesign`
+6. **Artifact Upload**: Built .app file saved as artifact for 30 days
+
+#### Viewing Build Artifacts
+1. Go to GitHub Actions page
+2. Select the corresponding workflow run
+3. Download `ios-build-unsigned` artifact
+
+**Note**: CI-built versions are not code-signed and cannot be installed directly on physical devices.
+
+## Code Signing and Distribution
+
+### Configuring Code Signing
+To publish to the App Store or install on physical devices, you need:
+
+1. **Apple Developer Account** (Individual or Enterprise)
+2. **Developer Certificates**
+   - Development Certificate
+   - Distribution Certificate
+3. **Provisioning Profile**
+4. **App ID** registered in Apple Developer Portal
+
+### Configuration in Xcode
+1. Open `ios/Runner.xcworkspace`
+2. Select Runner target
+3. Go to "Signing & Capabilities" tab
+4. Set Team (requires Apple ID login)
+5. Set Bundle Identifier
+6. Xcode will automatically manage certificates and Provisioning Profile
+
+### Building IPA for Distribution
+```bash
+# Build and archive using Xcode
+flutter build ipa --release
+
+# IPA file location
+# build/ios/ipa/*.ipa
+```
+
+## System Requirements
+
+### Development Environment
+- macOS 12.0 or higher
+- Xcode 14.0 or higher
+- CocoaPods 1.11 or higher
+- Flutter 3.32.4 (recommended)
+
+### Minimum iOS Version
+- iOS 12.0 (defined in `ios/Podfile`)
+
+## Common Issues
+
+### Q: Why use .xcworkspace instead of .xcodeproj?
+A: When a project uses CocoaPods, Pod dependencies are organized into a separate Xcode project. The `.xcworkspace` file contains both the main project and the Pods project, and must be used to ensure all dependencies are properly loaded.
+
+### Q: What to do after updating pubspec.yaml?
+A: After adding or updating dependencies, you need to run:
+```bash
+flutter pub get
+cd ios && pod install && cd ..
+```
+
+### Q: What if CI build fails?
+A: Common causes:
+1. Flutter version mismatch
+2. Dependency conflicts
+3. Pod installation failure
+4. Code analysis or test failures
+
+Check GitHub Actions logs for detailed error information.
+
+### Q: How to configure code signing in CI?
+A: You need to configure GitHub Secrets:
+- Apple certificate (.p12 format, base64 encoded)
+- Provisioning Profile
+- Certificate password
+- Keychain setup
+
+This requires additional configuration steps. Currently, CI uses the `--no-codesign` option for unsigned builds.
