Slider

A Jetpack Compose Slider component for selecting values from a range.

Android

Expo UI Slider matches the official Jetpack Compose Slider API and allows selecting values from a bounded range.

Installation

Terminal

- npx 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 slider

BasicSliderExample.tsx

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

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

  return (
    <Host matchContents>
      <Slider value={value} onValueChange={setValue} />
    </Host>
  );
}

Slider with custom range

Use the min and max props to define the slider's value range.

CustomRangeSliderExample.tsx

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

export default function CustomRangeSliderExample() {
  const [value, setValue] = useState(50);

  return (
    <Host matchContents>
      <Slider value={value} min={0} max={100} onValueChange={setValue} />
    </Host>
  );
}

Slider with steps

Use the steps prop to define discrete increments. Set steps to 0 for continuous values.

SteppedSliderExample.tsx

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

export default function SteppedSliderExample() {
  const [value, setValue] = useState(0);

  return (
    <Host matchContents>
      <Slider value={value} min={0} max={100} steps={10} onValueChange={setValue} />
    </Host>
  );
}

Custom colors

Use the colors prop to override the default Material3 colors for the slider's thumb, track, and tick marks.

CustomColorsSliderExample.tsx

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

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

  return (
    <Host matchContents>
      <Slider
        value={value}
        colors={{
          thumbColor: '#6200EE',
          activeTrackColor: '#6200EE',
          inactiveTrackColor: '#E0E0E0',
        }}
        onValueChange={setValue}
      />
    </Host>
  );
}

Custom thumb and track

Use both Slider.Thumb and Slider.Track slots for a fully custom slider appearance.

FullyCustomSliderExample.tsx

import { useState } from 'react';
import { Host, Slider, Shape, Row, Box } from '@expo/ui/jetpack-compose';
import {
  fillMaxWidth,
  height,
  weight,
  size,
  clip,
  background,
  Shapes,
} from '@expo/ui/jetpack-compose/modifiers';

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

  return (
    <Host matchContents>
      <Slider value={value} onValueChange={setValue}>
        <Slider.Thumb>
          <Box modifiers={[size(24, 24), clip(Shapes.Circle), background('#6200EE')]} />
        </Slider.Thumb>
        <Slider.Track>
          <Row modifiers={[fillMaxWidth(), height(8)]}>
            <Shape.RoundedCorner
              color="#6200EE"
              cornerRadii={{ topStart: 4, bottomStart: 4 }}
              modifiers={[weight(Math.max(value, 0.01)), height(8)]}
            />
            <Shape.RoundedCorner
              color="#BDBDBD"
              cornerRadii={{ topEnd: 4, bottomEnd: 4 }}
              modifiers={[weight(Math.max(1 - value, 0.01)), height(8)]}
            />
          </Row>
        </Slider.Track>
      </Slider>
    </Host>
  );
}
