[bug] Looking up a deactivated widget's ancestor is unsafe.

when I go back from my screen that exception fires Looking up a deactivated widget's ancestor is unsafe.
The issue happens on the disposing state, try to dispose the screen somehow and you will catch the exception in the console

the bug is coming from that part, when I commented it every thing worked well.

For me, the line that causes this is line #434 in nested_inner_scroll_coordinator.dart. Commenting out this line fixes the problem, but it doesn't seem like a good solution since the inner scroll position isn't being detached any more.
