React Native Slider | Track bar in React Native

React Native Slider

This is an Example to Show the Working of Slider in React Native. React Native Slider is a component to select a single value from a range of values. We have mostly seen slider while increasing or decreasing the volume or brightness of our phone. Here is the example of the slider which will be helpful for you to integrate slider in your app.

To Import Slider in Code

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

Render Using

  value='initial value'

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use Slider we need to install @react-native-community/slider dependency. To install this open the terminal and jump into your project using

cd ProjectName

Run the following command to install

npm install @react-native-community/slider --save

This command will copy all the dependency into your node_module directory. –save is optional, it is just to update the @react-native-community/slider dependency in your package.json file.

CocoaPods Installation

We need to install the pods for iOS

cd ios && pod install && cd ..


Open App.js in any code editor and replace the code with the following code


//React Native Slider

//import React in our code
import React, {useState} from 'react';

//import all the components we are going to use
import {View, Text, SafeAreaView, StyleSheet} from 'react-native';

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

const App = () => {
  const [sliderValue, setSliderValue] = useState(15);

  return (
    <SafeAreaView style={{flex: 1}}>
      <View style={styles.container}>
        {/*Text to show slider value*/}
        <Text style={{color: 'black'}}>
           Value of slider is : {sliderValue}

        {/*Slider with max, min, step and initial value*/}
            (sliderValue) => setSliderValue(sliderValue)

const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 20,
    justifyContent: 'center',
    backgroundColor: '#ecf0f1',

export default App;

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

To run the project on an Android Virtual Device or on real debugging device

react-native run-android

or on the iOS Simulator by running (macOS only)

react-native run-ios
