Add SlidingClippedNavBar()
as bottomNavigationBar
of Scaffold()
and body would be PageView()
with NeverScrollableScrollPhysics()
don't try to upate the seleted index from onPageChanged
or will see some weird behaviour. You can use Stack()
or AnimatedSwitcher()
for custom page transition animation.
Keep that in mind this navigation menu is taller than normal for small screen it might cover more screen real estate.
