Picker

A single-selection input with menu and wheel appearances.

Included in Expo Go

Changelog

Recommended version:
~56.0.26

Picker is a single-selection input. You can use <Picker.Item label value /> children to declare options so that the parent Picker reads them and renders a platform-appropriate dropdown or rotor.

The universal Picker is independent of @expo/ui/community/picker, which remains a compat shim for @react-native-picker/picker. Prefer this universal Picker for new code unless you specifically need the RN-Picker API surface.

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

Menu appearance (default)

PickerMenuExample.tsx
import { useState } from 'react';
import { Host, Row, Picker, Spacer, Text } from '@expo/ui';

const FLAVOURS = [
  { label: 'Vanilla', value: 'vanilla' },
  { label: 'Chocolate', value: 'chocolate' },
  { label: 'Strawberry', value: 'strawberry' },
];

export default function PickerMenuExample() {
  const [value, setValue] = useState('vanilla');

  return (
    <Host style={{ flex: 1 }}>
      <Row alignment="center" spacing={12} style={{ padding: 16 }}>
        <Text>Flavour:</Text>
        <Spacer flexible />
        <Picker selectedValue={value} onValueChange={setValue}>
          {FLAVOURS.map(f => (
            <Picker.Item key={f.value} label={f.label} value={f.value} />
          ))}
        </Picker>
      </Row>
    </Host>
  );
}

Wheel appearance

appearance="wheel" renders an inline scrollable rotor on iOS. On Android and web, this falls back to the platform's default dropdown (Material 3 doesn't ship a wheel-style picker).

PickerWheelExample.tsx
import { useState } from 'react';
import { Host, Column, Picker } from '@expo/ui';

const FLAVOURS = [
  { label: 'Vanilla', value: 'vanilla' },
  { label: 'Chocolate', value: 'chocolate' },
  { label: 'Strawberry', value: 'strawberry' },
];

export default function PickerWheelExample() {
  const [value, setValue] = useState('chocolate');

  return (
    <Host style={{ flex: 1 }}>
      <Column spacing={8} style={{ padding: 16 }}>
        <Picker selectedValue={value} onValueChange={setValue} appearance="wheel">
          {FLAVOURS.map(f => (
            <Picker.Item key={f.value} label={f.label} value={f.value} />
          ))}
        </Picker>
      </Column>
    </Host>
  );
}
