# BasicAlertDialog

A Jetpack Compose BasicAlertDialog component for displaying dialogs with custom content.
Android, Included in Expo Go

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

Expo UI BasicAlertDialog matches the official Jetpack Compose [BasicAlertDialog](https://developer.android.com/develop/ui/compose/components/dialog) API and displays a minimal dialog that accepts custom children as its content, giving you full control over the dialog layout.

## Installation

```sh
npx expo install @expo/ui
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## Usage

### Basic dialog with custom content

```tsx
import { useState } from 'react';
import {
  Host,
  BasicAlertDialog,
  Button,
  TextButton,
  Text,
  Surface,
  Column,
  Spacer,
} from '@expo/ui/jetpack-compose';
import {
  padding,
  wrapContentWidth,
  wrapContentHeight,
  clip,
  height,
  align,
  Shapes,
} from '@expo/ui/jetpack-compose/modifiers';

export default function BasicAlertDialogExample() {
  const [visible, setVisible] = useState(false);

  return (
    <Host matchContents>
      <Button onClick={() => setVisible(true)}>
        <Text>Open dialog</Text>
      </Button>
      {visible && (
        <BasicAlertDialog onDismissRequest={() => setVisible(false)}>
          <Surface
            tonalElevation={6}
            modifiers={[wrapContentWidth(), wrapContentHeight(), clip(Shapes.RoundedCorner(28))]}>
            <Column modifiers={[padding(16, 16, 16, 16)]}>
              <Text>
                This area typically contains the supportive text which presents the details
                regarding the Dialog's purpose.
              </Text>
              <Spacer modifiers={[height(24)]} />
              <TextButton onClick={() => setVisible(false)} modifiers={[align('centerEnd')]}>
                <Text>Confirm</Text>
              </TextButton>
            </Column>
          </Surface>
        </BasicAlertDialog>
      )}
    </Host>
  );
}
```
