Set AppBar in webview.launch(url) about flutter_webview_plugin HOT 2 CLOSED

Are you trying to achieve something similar to this ? (#30)

The plugin does not allow to manage multiple webview and the FlutterWebviewPlugin instance is a singleton,
so you can access to the current webview from anywhere and attach listener

from flutter_webview_plugin.

I was not aware that you could access the properties on flutterWebviewPlugin if you use WebviewScaffold. Maybe make that clearer in the documentation for people that dont know what a singleton is:

FlutterWebviewPlugin provide a singleton instance linked to one unique webview, so you can take control of the webview from anywhere in the app. That means that you can only have one webview open at a time and that you can use the FlutterWebviewPlugin instance to manipulate your WebviewScaffold.

I know that you can use the listeners to change the state which rerenders the widgets but the proposed api would make it alot easier to work with (but would be a breaking change). I should have put that into a seperate issue.
For example if you want to show the title and url of the page in the appbar (like twitter for example) you just need to use the variables instead of ataching listeners and remembering to dispose them again.
