React Native TextInput

React Native TextInput

In this post, you will get an Understanding of How TextInput Works in React Native. React Native TextInput is a basic component that allows the user to enter text, number, password, etc.

It has an onChangeText prop which requires a function that will be called every time when the text changes, and it also has a value prop that can set a default value into it.

To Import TextInput in the Code

import { TextInput } from 'react-native'

Render Using

  onChangeText={(userName) => setUserName(userName)}

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.


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


//React Native TextInput

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

//import all the components we are going to use
import {
} from 'react-native';

const App = () => {
  const [userName, setUserName] = useState('');
  return (
    <SafeAreaView style={{ flex: 1 }}>
      <View style={styles.container}>
        <Text>Insert any text in below input</Text>
          onChangeText={(userName) => setUserName(userName)}
        <Text style={{color: 'blue'}}>{userName}</Text>

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    marginTop: 20,
    backgroundColor: '#ffffff',
  input: {
    width: 250,
    height: 44,
    padding: 10,
    marginTop: 20,
    marginBottom: 10,
    backgroundColor: '#e8e8e8'

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
