flutter change bottomNavigationBar(TabBar) height

Question

I just found a way to change the height of AppBar with PreferredSize().

But I still not found a way modify the height of BottomNavigationBar and TabBar. Such widgets all hard coded, is there a way can change the widget height for thinner BottomBar and TabBar.

Answer 1

_BottomNavigationBarState class is private, and in it's build method there is string BoxConstraints(minHeight: kBottomNavigationBarHeight + additionalBottomPadding). There is no way to change this height without customization this class
