ScaffoldPrelayoutGeometry class Null safety
The geometry of the Scaffold after all its contents have been laid out except the FloatingActionButton.
The Scaffold passes this pre-layout geometry to its FloatingActionButtonLocation, which produces an Offset that the Scaffold uses to position the FloatingActionButton.
For a description of the Scaffold's geometry after it has finished laying out, see the ScaffoldGeometry.
