Getting Height of Scaffold's Bottom Navigation Bar in Flutter

Question

How can I get the height of the BottomNavigationBar of a Scaffold in Flutter? I know there is MediaQuery.of(context).size to get a screen size. Is there a similar method for BottomNavigationBar?

Answer 1

Container(
   width: MediaQuery.of(context).size.width,
   height: kBottomNavigationBarHeight,
   child: Scaffold(
       backgroundColor: Colors.transparent,
       body: null,
       bottomNavigationBar: BottomNavigationBar()
  )
)

This will create a Scaffold with enough room only for the BottomNavigationBar widget.

kBottomNavigationBarHeight is a constant, and can be found in the constants.dart file.
