AnimatableParameter<T> class abstract Animation

A wrapper around an animatable parameter of a widget that supports animating with Fleet.

value itself is not animated, can be changed at any time and immediately reflects the new value.

animatedValue is animated and changes over time to the new value.

At any given point in time there is exaclty one or none AnimationSpecs available from the mechanism that Fleet uses to bind AnimationSpecs to state changes.

When a new value is set, the currently available AnimationSpec is used to animate the change.
