How it works

Launch WebView Fullscreen with Flutter navigation

new MaterialApp(
      routes: {
        "/": (_) => new WebviewScaffold(
              url: "https://www.google.com",
              appBar: new AppBar(
                title: new Text("Widget webview"),
              ),
            )
      },
    );

FlutterWebviewPlugin provide a singleton instance linked to one unique webview, so you can take control of the webview from anywhere in the app

listen for events

final flutterWebviewPlugin = new FlutterWebviewPlugin();

flutterWebviewPlugin.onUrlChanged.listen((String url) {
  
});

Hidden WebView

final flutterWebviewPlugin = new FlutterWebviewPlugin();  

flutterWebviewPlugin.launch(url, hidden: true);

Close launched WebView

flutterWebviewPlugin.close();

Webview inside custom Rectangle

final flutterWebviewPlugin = new FlutterWebviewPlugin();  

flutterWebviewPlugin.launch(url,
                  fullScreen: false,
                  rect: new Rect.fromLTWH(
                      0.0, 
                      0.0, 
                      MediaQuery.of(context).size.width, 
                      300.0));
