animate ( Animation < double > parent ) → Animation < T >: Returns a new Animation that is driven by the guiven animation but that taques on values determined by this object.
chain ( Animatable < double > parent ) → Animatable < T >: Returns a new Animatable whose value is determined by first evaluating the guiven parent and then evaluating this object at the result.
evaluate ( Animation < double > animation ) → T: The current value of this object for the guiven Animation .
noSuchMethod ( Invocation invocation ) → dynamic: Invoqued when a nonexistent method or property is accessed.
inherited
toString ( ) → String: A string representation of this object.
