ScrollController not attached to any scroll views

Question

I\'m using CustomScrollView, and providing it with a controller. ScrollController works, I even added a listener to it and print out the position of the scroll view.

Answer 1

I found working solution, but frankly the method is not best practice, I suppose. In my case controller.jumpTo() was called before it was attached to any scroll view. In order to solve problem I delayed some milliseconds and then call .jumpTo(), because build will be called and controller will be attached to any scroll view.

Future.delayed(Duration(milliseconds: ), () {
         _scrollController.jumpTo(50.0);
        });

I full agree that it is bad solution, but It can solve problem.
