App Crashes after navigating to WebViewScaffold()

[ritvij-saxena]

I have a simple application where when I click a button, a web view should open with the default URL. When I navigate to the web view and come back, if navigate again to the web view, web view opens and then crashes the whole application.

Here is my code

import 'package:flutter/material.dart';
import 'package:flutter_webview_plugin/flutter_webview_plugin.dart';

class MethodsPage extends StatefulWidget {
  @override
  _MethodsPageState createState() => _MethodsPageState();
}

class _MethodsPageState extends State<MethodsPage> {
//  final flutterWebViewPlugin = FlutterWebviewPlugin();
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
          centerTitle: true,
          title: Text(
            'Methods',
            style: TextStyle(color: Colors.black),
          )),
      body: Center(child: RaisedButton(
        child: Text('Open View'), onPressed: openWebView,)),
    );
  }

  void openWebView() {
    Navigator.push(
        context, MaterialPageRoute(builder: (context) => WebUi()));
  }

}

class WebUi extends StatelessWidget {
  final flutterWebViewPlugin = FlutterWebviewPlugin();
  @override
  Widget build(BuildContext context) {
    return WebviewScaffold(
      appBar: AppBar(centerTitle: true,title: Text('Web UI'),),
      url: 'https://www.google.com',
      withZoom: true,
      bottomNavigationBar: BottomAppBar(
        child: Row(
          children: <Widget>[
            IconButton(
              icon: const Icon(Icons.arrow_back_ios),
              onPressed: () {
                flutterWebViewPlugin.goBack();
              },
            ),
            IconButton(
              icon: const Icon(Icons.arrow_forward_ios),
              onPressed: () {
                flutterWebViewPlugin.goForward();
              },
            ),
            IconButton(
              icon: const Icon(Icons.autorenew),
              onPressed: () {
                flutterWebViewPlugin.reload();
              },
            ),
          ],
        ),
      ),
    );
  }
}
