What is State and how is it used in React Native? |
|
Answer» It is used to control the components. The VARIABLE data can be stored in the state. It is mutable MEANS a state can change the value at any time. import React, {Component} from 'react'; import { Text, View } from 'react-native'; export default class App extends Component { state = { myState: 'State of Text Component' }updateState = () => this.setState({myState: 'The state is updated'})RENDER() {return (<View> <Text onPress={this.updateState}> {this.state.myState} </Text> </View> ); } }Here we create a Text component with state data. The content of the Text component will be updated whenever we CLICK on it. The state is updated by event onPress . |
