Migrating from the core react-native module

This module was created when the Slider was split out from the core of React Native. To migrate to this module you need to follow the installation instructions above and then change you imports from:

import { Slider } from 'react-native';

to:

import Slider from '@react-native-community/slider';

Usage

Example

import Slider from '@react-native-community/slider';

  <Slider
    style={{width: 200, height: 40}}
    minimumValue={0}
    maximumValue={1}
    minimumTrackTintColor="#FFFFFF"
    maximumTrackTintColor="#000000"
  />
