Use case

I have a multiple rows of TabBars & TabBarViews. Some of the view have large shadows. Currently, the TabBarView does not have a clipBehavior property to pass to the internal PageView. With this default behavior, it clips the shadow which requires some work around to prevent the clipping.

With default PageView clipBehavior

With Clip.none

Proposal

I suggest adding a clipBehavior argument on the TabBarView which will be passed to the PageView within the build method.
