An object that can produce a value of type
T given an Animation<double>
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.
Abstract const constructor. This constructor enables subclasses to provide
const constructors so that they can be used in const expressions.
Animation< double>parent) → Animation< T>
- Returns a new Animation that is driven by the given animation but that takes on values determined by this object.
Animatable< double>parent) → Animatable< T>
- Returns a new Animatable whose value is determined by first evaluating the given parent and then evaluating this object.
Animation< double>animation) → T
- The current value of this object for the given Animation.
Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
) → String
A string representation of this object.
double t) → T
Returns the value of the object at point
