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.

Modal bottom sheet with title, description, and action buttons

Installation

Terminal

- npx expo install @expo/ui

- yarn expo install @expo/ui

- pnpm expo install @expo/ui

- bun 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 { useColorScheme } from 'react-native';
import { Host, Column, Button, BottomSheet, Text } from '@expo/ui';

export default function BottomSheetExample() {
  const [isPresented, setIsPresented] = useState(false);
  const colorScheme = useColorScheme();
  const ink = { color: colorScheme === 'dark' ? '#FFFFFF' : '#000000' };

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

Hiding the drag indicator

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

BottomSheetNoIndicatorExample.tsx

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

export default function BottomSheetNoIndicatorExample() {
  const [isPresented, setIsPresented] = useState(false);
  const colorScheme = useColorScheme();
  const ink = { color: colorScheme === 'dark' ? '#FFFFFF' : '#000000' };

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

Content padding

The sheet insets its content by default. Pass contentPadding to change that inset — 0 lets a row, image, or divider reach the sheet's edges.

BottomSheetContentPaddingExample.tsx

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

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

  return (
    <>
      <Host matchContents>
        <Button label="Open" onPress={() => setIsPresented(true)} />
      </Host>
      <BottomSheet
        isPresented={isPresented}
        onDismiss={() => setIsPresented(false)}
        contentPadding={0}>
        <Column>
          <Column style={{ backgroundColor: '#0a84ff', padding: 16 }}>
            <Text textStyle={{ color: '#FFFFFF' }}>This banner reaches the sheet's edge.</Text>
          </Column>
          <Button label="Close" onPress={() => setIsPresented(false)} />
        </Column>
      </BottomSheet>
    </>
  );
}

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

export default function BottomSheetSnapPointsExample() {
  const [isPresented, setIsPresented] = useState(false);
  const colorScheme = useColorScheme();
  const ink = { color: colorScheme === 'dark' ? '#FFFFFF' : '#000000' };

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

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, useColorScheme } 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);
  const colorScheme = useColorScheme();
  const ink = { color: colorScheme === 'dark' ? '#FFFFFF' : '#000000' };

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

Component

`BottomSheet`

Android

iOS

Web

Type: React.Element<BottomSheetProps>

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

Props for the BottomSheet component, a modal sheet that slides up from the bottom of the screen.

BottomSheetProps

`children`

Android

iOS

Web

Optional • Type: ReactNode

Content to render inside the bottom sheet.

`contentPadding`

Android

iOS

Web

Optional • Type: BottomSheetContentPadding

Padding between the sheet and children, in dp on Android, points on iOS, and CSS pixels on web. Pass 0 for content that reaches the sheet's edges.

When omitted, each platform keeps the inset it applies by default.

Example

``contentPadding={0} — full-bleed content

Example

``contentPadding={{ top: 8, bottom: 24 }} — no horizontal inset

`isPresented`

Android

iOS

Web

Type: boolean

Whether the bottom sheet is currently visible.

`modifiers`

Android

iOS

Web

Optional • Type: ModifierConfig[]

Platform-specific modifier escape hatch. Pass an array of modifier configs from @expo/ui/swift-ui/modifiers or @expo/ui/jetpack-compose/modifiers.

`onDismiss`

Android

iOS

Web

Type: () => void

Called when the bottom sheet is dismissed by the user (e.g. swiping down or tapping the overlay).

`scrimColor`

Android

Optional • Type: ColorValue

The color of the scrim overlay rendered behind the bottom sheet. Pass 'transparent' to make the backdrop invisible while still blocking touches.

`shouldDismissOnBackPress`

Android

Optional • Type: boolean • Default: true

Whether pressing the Android hardware back button (or back gesture) dismisses the bottom sheet. When false, the back press does not dismiss the sheet (note: the press still does not reach React Native's BackHandler).

`shouldDismissOnClickOutside`

Android

Optional • Type: boolean • Default: true

Whether tapping the backdrop (scrim) dismisses the bottom sheet. When false, the sheet stays open until the user explicitly closes it (e.g. via a button).

`showDragIndicator`

Android

iOS

Web

Optional • Type: boolean • Default: true

Whether to show a drag indicator at the top of the sheet.

`snapPoints`

Android

iOS

Web

Optional • Type: SnapPoint[]

Heights the sheet can rest at. When omitted, the sheet auto-sizes to its content. See SnapPoint for the supported values.

Example

``['half', 'full'] — draggable between half and full

Example

``['full'] — always full height

`testID`

Android

iOS

Web

Optional • Type: string

Identifier used to locate the component in end-to-end tests.

Types

`BottomSheetContentPadding`

Android

iOS

Web

Padding between a BottomSheet and its content — a single value applied to every edge, or per-edge values where an edge that is left out is 0.

Type: number or object shaped as below:

Property	Type	Description
bottom(optional)	`number`	-
left(optional)	`number`	-
right(optional)	`number`	-

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:

Property	Type	Description
fraction	`number`	-
