Usage

Continuous slider

The default range is [0, 1].

ContinuousSliderExample.tsx

import { useState } from 'react';
import { Host, Slider } from '@expo/ui';

export default function ContinuousSliderExample() {
  const [value, setValue] = useState(0.5);

  return (
    <Host matchContents={{ vertical: true }} style={{ width: '100%' }}>
      <Slider value={value} onValueChange={setValue} />
    </Host>
  );
}

Stepped slider with custom range

Use min, max, and step to constrain the values produced by the slider.

SteppedSliderExample.tsx

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

export default function SteppedSliderExample() {
  const [volume, setVolume] = useState(50);
  const colorScheme = useColorScheme();

  return (
    <Host matchContents={{ vertical: true }} style={{ width: '100%' }}>
      <Column spacing={8}>
        <Text textStyle={{ color: colorScheme === 'dark' ? '#FFFFFF' : '#000000' }}>
          {`Volume: ${volume}`}
        </Text>
        <Slider value={volume} onValueChange={setVolume} min={0} max={100} step={10} />
      </Column>
    </Host>
  );
}
