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

Usage

Basic checkbox

CheckboxExample.tsx

import { useState } from 'react';
import { Host, Checkbox } from '@expo/ui/jetpack-compose';

export default function CheckboxExample() {
  const [checked, setChecked] = useState(false);

  return (
    <Host matchContents>
      <Checkbox value={checked} onCheckedChange={setChecked} />
    </Host>
  );
}

Custom colors

CustomColorsExample.tsx

import { useState } from 'react';
import { Host, Checkbox } from '@expo/ui/jetpack-compose';

export default function CustomColorsExample() {
  const [checked, setChecked] = useState(false);

  return (
    <Host matchContents>
      <Checkbox
        value={checked}
        onCheckedChange={setChecked}
        colors={{
          checkedColor: '#6200EE',
          checkmarkColor: '#FFFFFF',
        }}
      />
    </Host>
  );
}

Select all (TriStateCheckbox)

Use TriStateCheckbox for a parent checkbox that reflects the state of its children. It supports three states: 'on', 'off', and 'indeterminate'.

Apply the toggleable modifier to each Row to make the entire row (checkbox + label) tappable with correct accessibility semantics. When using toggleable on the row, omit onCheckedChange/onClick from the checkbox itself to avoid double-handling.

SelectAllExample.tsx

import { useState } from 'react';
import { Host, Checkbox, TriStateCheckbox, Row, Column, Text } from '@expo/ui/jetpack-compose';
import { toggleable } from '@expo/ui/jetpack-compose/modifiers';

export default function SelectAllExample() {
  const [child1, setChild1] = useState(false);
  const [child2, setChild2] = useState(false);
  const [child3, setChild3] = useState(false);

  const parentState =
    child1 && child2 && child3 ? 'on' : !child1 && !child2 && !child3 ? 'off' : 'indeterminate';

  return (
    <Host matchContents>
      <Column>
        <Row
          verticalAlignment="center"
          modifiers={[
            toggleable(
              parentState === 'on',
              () => {
                const newState = parentState !== 'on';
                setChild1(newState);
                setChild2(newState);
                setChild3(newState);
              },
              { role: 'checkbox' }
            ),
          ]}>
          <TriStateCheckbox state={parentState} />
          <Text>Select all</Text>
        </Row>
        <Row
          verticalAlignment="center"
          modifiers={[toggleable(child1, () => setChild1(!child1), { role: 'checkbox' })]}>
          <Checkbox value={child1} />
          <Text>Option 1</Text>
        </Row>
        <Row
          verticalAlignment="center"
          modifiers={[toggleable(child2, () => setChild2(!child2), { role: 'checkbox' })]}>
          <Checkbox value={child2} />
          <Text>Option 2</Text>
        </Row>
        <Row
          verticalAlignment="center"
          modifiers={[toggleable(child3, () => setChild3(!child3), { role: 'checkbox' })]}>
          <Checkbox value={child3} />
          <Text>Option 3</Text>
        </Row>
      </Column>
    </Host>
