ImplicitlyAnimatedWidgetState<T extends ImplicitlyAnimatedWidget> class

A base class for 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.

Subclasses must implement the forEachTween method to allow ImplicitlyAnimatedWidgetState to iterate through the subclasses' widget's fields and animate them.
