BottomSheet

A modal sheet that slides up from the bottom of the screen.

Changelog

A modal sheet that slides up from the bottom of the screen. The sheet's visibility is controlled — toggle isPresented from React state and dismiss it from onDismiss (called when the user swipes down or taps the overlay).

On iOS, to show a bottom sheet on top of another, nest the second BottomSheet inside the first sheet's content rather than beside it. This is a limitation of the underlying SwiftUI sheet modifier. See how to present multiple sheets for more information.

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

BottomSheetExample.tsx

import { useState } from 'react';
import { Host, Column, Button, BottomSheet, Text } from '@expo/ui';

export default function BottomSheetExample() {
  const [isPresented, setIsPresented] = useState(false);

  return (
    <Host style={{ flex: 1 }}>
      <Button label="Open sheet" onPress={() => setIsPresented(true)} />
      <BottomSheet isPresented={isPresented} onDismiss={() => setIsPresented(false)}>
        <Column spacing={12}>
          <Text textStyle={{ fontSize: 18, fontWeight: '700' }}>Sheet contents</Text>
          <Text>Drag down or tap the overlay to dismiss.</Text>
          <Button label="Close" onPress={() => setIsPresented(false)} />
        </Column>
      </BottomSheet>
    </Host>
  );
}

Hiding the drag indicator

Pass showDragIndicator={false} for sheets without a handle.

BottomSheetNoIndicatorExample.tsx

import { useState } from 'react';
import { Host, Button, BottomSheet, Text } from '@expo/ui';

export default function BottomSheetNoIndicatorExample() {
  const [isPresented, setIsPresented] = useState(false);

  return (
    <Host style={{ flex: 1 }}>
      <Button label="Open" onPress={() => setIsPresented(true)} />
      <BottomSheet
        isPresented={isPresented}
        onDismiss={() => setIsPresented(false)}
        showDragIndicator={false}>
        <Text>No drag handle.</Text>
      </BottomSheet>
    </Host>
  );
}

Snap points

Pass snapPoints to let the user drag the sheet between multiple resting heights. You can use the semantic values 'half' and 'full' for cross-platform parity. The { fraction } and { height } forms are honored precisely on iOS and web.

When sheet content can be taller than the smallest snap point, wrap it in a ScrollView so the overflow scrolls correctly.

BottomSheetSnapPointsExample.tsx

import { useState } from 'react';
import { Host, BottomSheet, Button, Column, ScrollView, Text } from '@expo/ui';

export default function BottomSheetSnapPointsExample() {
  const [isPresented, setIsPresented] = useState(false);

  return (
    <Host style={{ flex: 1 }}>
      <Button label="Open" onPress={() => setIsPresented(true)} />
      <BottomSheet
        isPresented={isPresented}
        onDismiss={() => setIsPresented(false)}
        snapPoints={['half', 'full']}>
        <ScrollView>
          <Column spacing={12}>
            <Text textStyle={{ fontSize: 20, fontWeight: '700' }}>Half / full sheet</Text>
            <Text>Drag the sheet between half and full screen height.</Text>
          </Column>
        </ScrollView>
      </BottomSheet>
    </Host>
  );
}

On Android, { fraction } and { height } snap to the nearest of 'half' / 'full' — the underlying ModalBottomSheet only supports two resting states. The partial state is only visible when content is tall enough to exceed Material's partial threshold; give the content an explicit height or fill the available space if you need the half state on short content.

Scrollable React Native content

The bottom sheet supports a React Native list such as FlatList (or a high-performance list like FlashList or Legend List) as a child when wrapped in RNHostView. snapPoints sizes the sheet, and the list scrolls within that height. With nestedScrollEnabled, the list scrolls its own content first; once it reaches the top edge, the remaining drag moves the sheet.

BottomSheetScrollableExample.tsx

import { useState } from 'react';
import { FlatList, Text } from 'react-native';
import { Host, BottomSheet, Button, RNHostView } from '@expo/ui';

const DATA = Array.from({ length: 50 }, (_, i) => `Item ${i + 1}`);

export default function BottomSheetScrollableExample() {
  const [isPresented, setIsPresented] = useState(false);

  return (
    <Host matchContents>
      <Button label="Open" onPress={() => setIsPresented(true)} />
      <BottomSheet
        isPresented={isPresented}
        onDismiss={() => setIsPresented(false)}
        snapPoints={['half', 'full']}>
        <RNHostView>
          <FlatList
            nestedScrollEnabled
            style={{ flex: 1 }}
            data={DATA}
            keyExtractor={item => item}
            renderItem={({ item }) => <Text style={{ padding: 16 }}>{item}</Text>}
          />
        </RNHostView>
      </BottomSheet>
    </Host>
  );
}

Types

`SnapPoint`

A snap point describing one of the heights a BottomSheet can rest at.

'half' — Approximately half-screen.
'full' — Fully expanded.
{ fraction } — A fraction of the screen height (0–1). iOS / web only.
{ height } — A fixed pixel height. iOS / web only.

On Android, { fraction } and { height } snap to the nearest of 'half' / 'full'. See the component docs for platform behavior notes.

Type: 'half' or 'full' or object shaped as below:
