description: `@expo/ui/jetpack-compose` package lets you use Jetpack Compose Views and modifiers in your app.

> The instructions in this skill apply to SDK 55 only. For other SDK versions, refer to the Expo UI Jetpack Compose docs for that version for the most accurate information.
## When to Use
- You need to build Android-native UI in Expo using `@expo/ui/jetpack-compose`.
- The task involves choosing Compose views or modifiers, embedding them in `Host`, or translating Jetpack Compose patterns into Expo UI code.
- You are working specifically against Expo SDK 55 behavior for Jetpack Compose integration.
## Installation
```bash
npx expo install @expo/ui
```
A native rebuild is required after installation (`npx expo run:android`).
## Instructions
- Expo UI's API mirrors Jetpack Compose's API. Use Jetpack Compose and Material Design 3 knowledge to decide which components or modifiers to use.
- Components are imported from `@expo/ui/jetpack-compose`, modifiers from `@expo/ui/jetpack-compose/modifiers`.
- When about to use a component, fetch its docs to confirm the API - https://docs.expo.dev/versions/v55.0.0/sdk/ui/jetpack-compose/{component-name}/index.md
- When unsure about a modifier's API, refer to the docs - https://docs.expo.dev/versions/v55.0.0/sdk/ui/jetpack-compose/modifiers/index.md
- Every Jetpack Compose tree must be wrapped in `Host`. Use `<Host matchContents>` for intrinsic sizing, or `<Host style={{ flex: 1 }}>` when you need explicit size (e.g. as a parent of `LazyColumn`). Example:
```jsx
import { Host, Column, Button, Text } from "@expo/ui/jetpack-compose";
import { fillMaxWidth, paddingAll } from "@expo/ui/jetpack-compose/modifiers";
<Host matchContents>
<Column verticalArrangement={{ spacedBy: 8 }} modifiers={[fillMaxWidth(), paddingAll(16)]}>
<Text style={{ typography: "titleLarge" }}>Hello</Text>
<Button onPress={() => alert("Pressed!")}>Press me</Button>
</Column>
</Host>;
```
## Key Components
- **LazyColumn** — Use instead of react-native `ScrollView`/`FlatList` for scrollable lists. Wrap in `<Host style={{ flex: 1 }}>`.
- **Icon** — Use `<Icon source={require('./icon.xml')} size={24} />` with Android XML vector drawables from [Material Symbols](https://fonts.google.com/icons).
