Usage

Toggle switch

ToggleSwitchExample.tsx

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

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

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

Custom colors

CustomColorsExample.tsx

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

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

  return (
    <Host matchContents>
      <Switch
        value={checked}
        onCheckedChange={setChecked}
        colors={{
          checkedThumbColor: '#6200EE',
          checkedTrackColor: '#EDE9FE',
          uncheckedThumbColor: '#9CA3AF',
          uncheckedTrackColor: '#F3F4F6',
          uncheckedBorderColor: '#D1D5DB',
        }}
      />
    </Host>
  );
}

Custom thumb content

Use Switch.ThumbContent to render a custom element inside the thumb. Switch.DefaultIconSize gives you the M3 default icon size so your content fits perfectly.

ThumbContentExample.tsx

import { useState } from 'react';
import { Host, Switch, Box } from '@expo/ui/jetpack-compose';
import { size, clip, background, Shapes } from '@expo/ui/jetpack-compose/modifiers';

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

  return (
    <Host matchContents>
      <Switch
        value={checked}
        onCheckedChange={setChecked}
        colors={{
          checkedThumbColor: '#7C3AED',
          checkedTrackColor: '#EDE9FE',
          checkedIconColor: '#7C3AED',
          uncheckedThumbColor: '#9CA3AF',
          uncheckedTrackColor: '#F3F4F6',
          uncheckedBorderColor: '#D1D5DB',
          uncheckedIconColor: '#9CA3AF',
        }}>
        <Switch.ThumbContent>
          <Box
            modifiers={[
              size(Switch.DefaultIconSize, Switch.DefaultIconSize),
              clip(Shapes.Circle),
              background(checked ? '#FFFFFF' : '#E5E7EB'),
            ]}
          />
        </Switch.ThumbContent>
      </Switch>
    </Host>
  );
