Animation<T> class abstract

An animation with a value of type T.

This is the core abstraction for animations. It extends Listenable so widgets can subscribe to value changes, and ValueListenable so the current value is always accessible.

Concrete implementations include AnimationController (which drives the animation) and _AnimatedEvaluation (which applies an Animatable to a parent animation).
