FloatingActionButtonLocation class
An object that defines a position for the FloatingActionButton based on the Scaffold's ScaffoldPrelayoutGeometry.
Flutter provides FloatingActionButtonLocations for the common FloatingActionButton placements in Material Design applications. These locations are available as static members of this class.
See also:
- FloatingActionButton, which is a circular button typically shown in the bottom right corner of the app.
- FloatingActionButtonAnimator, which is used to animate the Scaffold.floatingActionButton from one FloatingActionButtonLocation to another.
- ScaffoldPrelayoutGeometry, the geometry that FloatingActionButtonLocations use to position the FloatingActionButton.
Constructors
