i started my project to make WhatsApp clone to learn now i have chalange to my AppBar ( animated , scrollbe , design )

i have used DefaultTabController with : Scaffold with : NestedScrollView with : SliversAppBar with : TapBar

and TapBar and in body TapBarView with 4 page

first page is non Scrolling (i did it ) ,not scroll and not animated Appbar ( cant handel , , i can handel for all Tap but i need to only this page )

second ,third and forth page is 3 diffrent type of list conected with Taps so i used NestedScrollView with CustomScrollView ,, But i cant Handel the change in AppPar PopUPMenuButtom in Actions (cant handel)

and i cant handel the first page behavior of AppBar ,, its allows about AppBar

so i asked , maybe found any solution for this AppBar
