Usage

Import the WebView component from react-native-webview and use it like so:

import React, { Component } from 'react';
import { StyleSheet, Text, View } from 'react-native';
import { WebView } from 'react-native-webview';

// ...
class MyWebComponent extends Component {
  render() {
    return <WebView source={{ uri: 'https://reactnative.dev/' }} />;
  }
}

Common issues

• If you're getting Invariant Violation: Native component for "RNCWebView does not exist" it likely means you forgot to run react-native link or there was some error with the linking process
• If you encounter a build error during the task :app:mergeDexRelease, you need to enable multidex support in android/app/build.gradle as discussed in this issue
