tpackard1 / fluttery_music_player Goto Github PK

I am getting this error: reference to an enclosing class method cannot be extracted. I have included the Flutter doctor results down below. And I have put an example of the code I've written in my repository and at line 98 I'm trying to refactor RadialDragGestureDetector. You can also go to youtube.com and type in fluttery challenge music player then go to 1:11:42ish and that is the part in the video that I am having difficulty with. If you would like anymore information just let me know. Any help will be greatly appreciated!
