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.

CustomScrollView(     controller: _scrollController, 

Now, all i'm trying to do is jump to position 50.0 inside initState() function.

_scrollController.jumpTo(50.0); 

But, i get the error

scrollController not attached to any scroll views

Answer 1

Check if the scrollController is attached to a scroll view by using its hasClients property first.

if (_scrollController.hasClients)      _scrollController.jumpTo(50.0);
