miniCenterFloat constant Null safety
Centered FloatingActionButton, floating at the bottom of the screen, optimized for mini floating action buttons.
This is intended to be used with FloatingActionButton.mini set to true, so that the floating action button appears to align horizontally with the locations FloatingActionButtonLocation.miniStartFloat and FloatingActionButtonLocation.miniEndFloat.
Compared to FloatingActionButtonLocation.centerFloat, floating action buttons using this location will move vertically down by kMiniButtonOffsetAdjustment.
Implementation
static const FloatingActionButtonLocation miniCenterFloat = _MiniCenterFloatFabLocation();
