ImplicitlyAnimatedWidget class

An abstract class for building widgets that animate changes to their properties.

Widgets of this type will not animate when they are first added to the widget tree. Rather, when they are rebuilt with different values, they will respond to those changes by animating the changes over a specified duration.

Which properties are animated is left up to the subclass. Subclasses' States must extend ImplicitlyAnimatedWidgetState and provide a way to visit the relevant fields to animate.
