                url: webUrl,
                withJavascript: true,

                persistentFooterButtons: <Widget>[
                  RaisedBtn(
                    onPressed: (){
                      Screen();

                    },
                    text: "Confirm",
                  )
                ],
              ),
            ),

Answer 1

please check example below. Flutter webview has single instance which you can retrieve as FlutterWebviewPlugin()

 import 'package:flutter_webview_plugin/flutter_webview_plugin.dart';

    final _loginWebView = FlutterWebviewPlugin();

    _onUrlChanged = _loginWebView.onUrlChanged.listen((String url) {
            //check is it right url for navigation and navigate back or do nothing
        });

Important! Do not forget to dispose it.
