Changelog

Expo UI ModalBottomSheet matches the official Jetpack Compose Bottom Sheet API and displays content in a modal sheet that slides up from the bottom.

Installation

Terminal

- npx expo install @expo/ui

If you are installing this in an existing React Native app, make sure to install expo in your project.

Usage

Basic bottom sheet

Use ref.hide() to programmatically dismiss the sheet with an animation before unmounting it.

BasicBottomSheetExample.tsx

import { useRef, useState } from 'react';
import { Host, ModalBottomSheet, Button, Column, Text } from '@expo/ui/jetpack-compose';
import type { ModalBottomSheetRef } from '@expo/ui/jetpack-compose';
import { paddingAll } from '@expo/ui/jetpack-compose/modifiers';

export default function BasicBottomSheetExample() {
  const [visible, setVisible] = useState(false);
  const sheetRef = useRef<ModalBottomSheetRef>(null);

  const hideSheet = async () => {
    await sheetRef.current?.hide();
    setVisible(false);
  };

  return (
    <Host matchContents>
      <Button onClick={() => setVisible(true)}>
        <Text>Open Sheet</Text>
      </Button>
      {visible && (
        <ModalBottomSheet ref={sheetRef} onDismissRequest={() => setVisible(false)}>
          <Column verticalArrangement={{ spacedBy: 12 }} modifiers={[paddingAll(24)]}>
            <Text>Hello from bottom sheet!</Text>
            <Text>You can add more content here.</Text>
            <Button onClick={hideSheet}>
              <Text>Close</Text>
            </Button>
          </Column>
        </ModalBottomSheet>
      )}
    </Host>
  );
}

Skip partially expanded state

When skipPartiallyExpanded is set, the sheet opens directly in the fully expanded state instead of stopping at the half-height position first.

SkipPartiallyExpandedExample.tsx

import { useRef, useState } from 'react';
import { Host, ModalBottomSheet, Button, Column, Text } from '@expo/ui/jetpack-compose';
import type { ModalBottomSheetRef } from '@expo/ui/jetpack-compose';
import { paddingAll } from '@expo/ui/jetpack-compose/modifiers';

export default function SkipPartiallyExpandedExample() {
  const [visible, setVisible] = useState(false);
  const sheetRef = useRef<ModalBottomSheetRef>(null);

  const hideSheet = async () => {
    await sheetRef.current?.hide();
    setVisible(false);
  };

  return (
    <Host matchContents>
      <Button onClick={() => setVisible(true)}>
        <Text>Open Sheet</Text>
      </Button>
      {visible && (
        <ModalBottomSheet
          ref={sheetRef}
          onDismissRequest={() => setVisible(false)}
          skipPartiallyExpanded>
          <Column verticalArrangement={{ spacedBy: 12 }} modifiers={[paddingAll(24)]}>
            <Text>This sheet skips the partially expanded state.</Text>
            <Text>It opens directly in the fully expanded position.</Text>
            <Button onClick={hideSheet}>
              <Text>Close</Text>
            </Button>
          </Column>
        </ModalBottomSheet>
      )}
    </Host>
  );
}

Custom colors

Use containerColor, contentColor, and scrimColor to customize the sheet's appearance.

CustomColorsExample.tsx

import { useRef, useState } from 'react';
import { Host, ModalBottomSheet, Button, Column, Text } from '@expo/ui/jetpack-compose';
import type { ModalBottomSheetRef } from '@expo/ui/jetpack-compose';
import { paddingAll } from '@expo/ui/jetpack-compose/modifiers';

export default function CustomColorsExample() {
  const [visible, setVisible] = useState(false);
  const sheetRef = useRef<ModalBottomSheetRef>(null);

  const hideSheet = async () => {
    await sheetRef.current?.hide();
    setVisible(false);
  };

  return (
    <Host matchContents>
      <Button onClick={() => setVisible(true)}>
        <Text>Open Colored Sheet</Text>
      </Button>
      {visible && (
        <ModalBottomSheet
          ref={sheetRef}
          onDismissRequest={() => setVisible(false)}
          containerColor="#1a1a2e"
          contentColor="#e0e0e0"
          scrimColor="#806200EE">
          <Column verticalArrangement={{ spacedBy: 12 }} modifiers={[paddingAll(24)]}>
            <Text>Custom styled bottom sheet.</Text>
            <Text>Dark container with a purple scrim overlay.</Text>
            <Button onClick={hideSheet}>
              <Text>Close</Text>
            </Button>
          </Column>
        </ModalBottomSheet>
      )}
    </Host>
  );
}

Custom drag handle

Use ModalBottomSheet.DragHandle slot to provide a custom drag handle, or set showDragHandle={false} to hide it entirely.

CustomDragHandleExample.tsx

import { useRef, useState } from 'react';
import { Host, ModalBottomSheet, Button, Column, Box, Text } from '@expo/ui/jetpack-compose';
import type { ModalBottomSheetRef } from '@expo/ui/jetpack-compose';
import {
  background,
  clip,
  fillMaxWidth,
  height,
  padding,
  Shapes,
  width,
} from '@expo/ui/jetpack-compose/modifiers';

export default function CustomDragHandleExample() {
  const [visible, setVisible] = useState(false);
  const sheetRef = useRef<ModalBottomSheetRef>(null);

  const hideSheet = async () => {
    await sheetRef.current?.hide();
    setVisible(false);
  };

  return (
    <Host matchContents>
      <Button onClick={() => setVisible(true)}>
        <Text>Open Custom Handle Sheet</Text>
      </Button>
      {visible && (
        <ModalBottomSheet ref={sheetRef} onDismissRequest={() => setVisible(false)}>
          <ModalBottomSheet.DragHandle>
            <Column horizontalAlignment="center" modifiers={[fillMaxWidth(), padding(0, 12, 0, 8)]}>
              <Box modifiers={[width(60), height(6), clip(Shapes.Circle), background('#6200EE')]} />
            </Column>
          </ModalBottomSheet.DragHandle>
          <Column verticalArrangement={{ spacedBy: 12 }} modifiers={[padding(16, 16, 16, 16)]}>
            <Button onClick={hideSheet}>
              <Text>Close</Text>
            </Button>
          </Column>
        </ModalBottomSheet>
      )}
    </Host>
  );
}

React Native content inside a bottom sheet

Use RNHostView to embed interactive React Native views inside a Compose bottom sheet. This lets you mix Compose layout with RN components like Pressable and Text.

RNContentBottomSheetExample.tsx

import { useRef, useState } from 'react';
import { Host, ModalBottomSheet, Button, Column, RNHostView, Text } from '@expo/ui/jetpack-compose';
import type { ModalBottomSheetRef } from '@expo/ui/jetpack-compose';
import { padding } from '@expo/ui/jetpack-compose/modifiers';
import { Pressable, Text as RNText, View } from 'react-native';

export default function RNContentBottomSheetExample() {
  const [visible, setVisible] = useState(false);
  const sheetRef = useRef<ModalBottomSheetRef>(null);

  const hideSheet = async () => {
    await sheetRef.current?.hide();
    setVisible(false);
  };

  return (
    <Host matchContents>
      <Button onClick={() => setVisible(true)}>
        <Text>Open RN Content Sheet</Text>
      </Button>
      {visible && (
        <ModalBottomSheet
          ref={sheetRef}
          onDismissRequest={() => setVisible(false)}
          skipPartiallyExpanded={false}>
          <Column verticalArrangement={{ spacedBy: 16 }} modifiers={[padding(16, 16, 16, 16)]}>
            <Text>Mixing Compose + RN in a Bottom Sheet</Text>
            <RNHostView matchContents>
              <View>
                <RNText style={{ fontSize: 18, fontWeight: 'bold', marginBottom: 8 }}>
                  React Native Content
                </RNText>
                <Pressable
                  style={{
                    backgroundColor: '#007AFF',
                    padding: 12,
                    borderRadius: 8,
                    alignItems: 'center',
                  }}
                  onPress={hideSheet}>
                  <RNText style={{ color: 'white', fontWeight: '600' }}>Close</RNText>
                </Pressable>
              </View>
            </RNHostView>
          </Column>
        </ModalBottomSheet>
      )}
    </Host>
  );
}

React Native content with flex

Use RNHostView without matchContents to let the RN view fill the remaining space inside the sheet. Combine with a fixed height modifier on the parent Column to control the sheet size.

FlexRNContentExample.tsx

import { useRef, useState } from 'react';
import { Host, ModalBottomSheet, Button, Column, RNHostView, Text } from '@expo/ui/jetpack-compose';
import type { ModalBottomSheetRef } from '@expo/ui/jetpack-compose';
import { height, padding } from '@expo/ui/jetpack-compose/modifiers';
import { Text as RNText, View } from 'react-native';

export default function FlexRNContentExample() {
  const [visible, setVisible] = useState(false);
  const sheetRef = useRef<ModalBottomSheetRef>(null);

  const hideSheet = async () => {
    await sheetRef.current?.hide();
    setVisible(false);
  };

  return (
    <Host matchContents>
      <Button onClick={() => setVisible(true)}>
        <Text>Open Flex Content Sheet</Text>
      </Button>
      {visible && (
        <ModalBottomSheet
          ref={sheetRef}
          onDismissRequest={() => setVisible(false)}
          skipPartiallyExpanded>
          <Column modifiers={[height(400), padding(16, 16, 16, 16)]}>
            <Text>RN View with flex: 1</Text>
            <RNHostView>
              <View style={{ flex: 1, backgroundColor: '#9B59B6', borderRadius: 10 }}>
                <RNText
                  style={{
                    color: 'white',
                    fontSize: 18,
                    fontWeight: 'bold',
                    padding: 16,
                  }}>
                  React Native Content (flex: 1)
                </RNText>
              </View>
            </RNHostView>
          </Column>
        </ModalBottomSheet>
      )}
    </Host>
  );
}

Non-dismissible sheet

Combine properties, sheetGesturesEnabled to create a sheet that can only be closed programmatically.

NonDismissibleExample.tsx

import { useRef, useState } from 'react';
import { Host, ModalBottomSheet, Button, Column, Text } from '@expo/ui/jetpack-compose';
import type { ModalBottomSheetRef } from '@expo/ui/jetpack-compose';
import { paddingAll } from '@expo/ui/jetpack-compose/modifiers';

export default function NonDismissibleExample() {
  const [visible, setVisible] = useState(false);
  const sheetRef = useRef<ModalBottomSheetRef>(null);

  const hideSheet = async () => {
    await sheetRef.current?.hide();
    setVisible(false);
  };

  return (
    <Host matchContents>
      <Button onClick={() => setVisible(true)}>
        <Text>Open Non-Dismissible Sheet</Text>
      </Button>
      {visible && (
        <ModalBottomSheet
          ref={sheetRef}
          onDismissRequest={() => setVisible(false)}
          sheetGesturesEnabled={false}
          properties={{
            shouldDismissOnBackPress: false,
            shouldDismissOnClickOutside: false,
          }}>
          <Column verticalArrangement={{ spacedBy: 12 }} modifiers={[paddingAll(24)]}>
            <Text>This sheet cannot be dismissed by swiping, back press, or tapping outside.</Text>
            <Text>Only the button below will close it.</Text>
            <Button onClick={hideSheet}>
              <Text>Close</Text>
            </Button>
          </Column>
        </ModalBottomSheet>
      )}
    </Host>
  );
}
