ImplicitlyAnimatedWidgetState<T extends ImplicitlyAnimatedWidget> class
Null safety
A base class for the State of widgets with implicit animations.
ImplicitlyAnimatedWidgetState requires that subclasses respond to the
animation themselves. If you would like setState() to be called
automatically as the animation changes, use AnimatedWidgetBaseState.
Properties that subclasses choose to animate are represented by Tween instances. Subclasses must implement the forEachTween method to allow ImplicitlyAnimatedWidgetState to iterate through the widget's fields and animate them.
