Can you try to use react-native-webview normally?

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

export default class App extends Component {
  render() {
    const html = `
      <html>
      <head></head>
      <body>
        <script>
          setTimeout(function () {
            window.ReactNativeWebView.postMessage("Hello!")
          }, 2000)
        </script>
      </body>
      </html>
    `;

    return (
      <View style={{ flex: 1 }}>
        <WebView
          source={{ html }}
          onMessage={event => {
            alert(event.nativeEvent.data);
          }}
        />
      </View>
    );
  }
}

I followed the post: (adding react-native-get-random-values package and importing it from index.js of my project.)
and now have that issue :
null is not an object (evaluating 'RNGetRandomValues.getRandomBase64')

I have this issue, with latest expo SDK version 39.
