Launching with rect causes an exception

[volgin]

This code works:
flutterWebviewPlugin.launch("https://google.com");

This code, however,

flutterWebviewPlugin.launch("https://google.com",
        rect: new Rect.fromLTRB(0.0, 0.0, 0.0, 0.0));

causes an exception. I tried with different rect settings, tried putting this code in different places - in initState(), in build(), in main.dart - with the same results:

I remember running into a similar issue. I ultimately put all of the creation logic in initState without using the rect property. Then I used flutterWebviewPlugin.resize(rect) inside build. This had the added benefit of also properly handling screen orientation changes.

[lejard-h]

did you solve your problem using flutterWebviewPlugin.resize or by updating flutter and the plugin ?

Hi, I updated to 0.1.6 and the error was still showing. I launched the webview inside initState and then called resize in my build and the 'The specified child already has a parent' error went away.

Same issue, blocker for whole application development. :(
