Hello @dickermoshe!
Did you try to use any of parameters: closeOnBackdropTap, closeOnBackButtonPressed, isBackdropInteractable?

Otherwise you can wrap the SlidingSheet in the Stack or sth similar to close it from the any place.

Did you try to use any of parameters: closeOnBackdropTap, closeOnBackButtonPressed, isBackdropInteractable?

Every variation of these 3 still results in the slider snapping back open

Otherwise you can wrap the SlidingSheet in the Stack or sth similar to close it from the any place.

If anyone comes here with this issue, they should use a CustomScrollView.
Use a SliverPersistentHeader with pinned: true and put the body in a SliverList.
