[rickyazhari]

i try to get web state to make some loading animation before show webview. but it did not listen at all. here sample original case

class _FullWeb extends State<FullWeb>{

   FlutterWebviewPlugin wv;
  
   @override
   initState(){
      wv = new FlutterWebviewPlugin();
      wv.onStateChanged.listen(webStateChanged);
   }
   
    @override
     Widget body(BuildContext context){
          return new Scaffold(
               body: new Builder(
                       builder: (parent) => buildbody
                )
          );
     }

   Widget buildBody(BuildContext context){
         wv.launch(url);
   }

   void webStateChanged(WebViewStateChanged change){
    Log.write("==============");
    Log.write("index : "+change.type.index.toString());
    Log.write("state : "+change.toString());
    Log.write("Nav type: "+change.navigationType.toString());
    Log.write("==============");
  }

after i re update version into the new one. i using version v1.3.0 and upgrade to v1.5.0. On state change has call back but got exception. it said

Exception has occurred. type '_InternalLinkedHashMap<dynamic, dynamic>' is not a subtype of type 'Map<String, dynamic>'

in file base.dart.

So i change Map argument from < String, dynamic> into <dynamic, dynamic> in line 159.
i will request pull later.
thanks

Wrapping the code in ``` would make it readable ;-)
You can still edit above comment and the backticks.
Thanks for the PR :)
