> 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.

## 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`. 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>;
```
