contentBottom property
final
The vertical distance from the Scaffold's origin to the bottom of Scaffold.body.
This is useful in a FloatingActionButtonLocation designed to place the FloatingActionButton at the bottom of the screen, while keeping it above the BottomSheet, the Scaffold.bottomNavigationBar, or the keyboard.
The Scaffold.body is laid out with respect to minInsets already. This
means that a FloatingActionButtonLocation does not need to factor in
minInsets.bottom
when aligning a FloatingActionButton to
contentBottom.
