AnimatedWidgetBaseState<T extends ImplicitlyAnimatedWidget> class Null safety

A base class for widgets with implicit animations that need to rebuild their widget tree as the animation runs.

This class calls build each frame that the animation ticks. For a variant that does not rebuild each frame, consider subclassing ImplicitlyAnimatedWidgetState directly.

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