WebView
WebView renders web content in a native view.
import React, { Component } from 'react';
import { WebView } from 'react-native';
class MyWeb extends Component {
render() {
return (
<WebView
source={{uri: 'https://github.com/facebook/react-native'}}
style={{marginTop: 20}}
/>
);
}
}
You can use this component to navigate back and forth in the web view's history and configure various properties for the web content.
