Animatable<T> class

An object that can produce a value of type T given an Animation<double> as input.

Typically, the values of the input animation are nominally in the range 0.0 to 1.0. In principle, however, any value could be provided.

The main subclass of Animatable is Tween.

Implemented by


Abstract const constructor. This constructor enables subclasses to provide const constructors so that they can be used in const expressions.
