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.
Initialize the scrollController:
ScrollController _scrollController = ScrollController();
Use the code bellow where you want to scroll:
SchedulerBinding.instance.addPostFrameCallback((_) { _scrollController.jumpTo(_scrollController.position.maxScrollExtent); });
