getScaleAnimation abstract method
Animates the scale of the FloatingActionButton.
The animation should both start and end with a value of 1.0.
For example, to create an animation that linearly scales out and then back in, you could join animations that pass each other:
@override
Animation<double> getScaleAnimation({required Animation<double> parent}) {
// The animations will cross at value 0, and the train will return to 1.0.
return TrainHoppingAnimation(
Tween<double>(begin: 1.0, end: -1.0).animate(parent),
Tween<double>(begin: -1.0, end: 1.0).animate(parent),
);
}
Implementation
Animation<double> getScaleAnimation({ required Animation<double> parent });
