Introduction

Since #103962, we can use the new Material 3 medium top app bar and large top app bar, though there are a few bugs regarding the use of SliverAppBar.medium and SliverAppBar.large in both CustomScrollView and NestedScrollView.

Split issues

• CustomScrollView applies overscroll effect on SliverAppBar #104437
• [Material 3] Using NestedScrollView with SliverAppBar makes content go behind it, even though it fits on the screen. #104440
• [Material 3] Using NestedScrollView with SliverAppBar does not show collapsed SliverAppBar #104442
