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.

Constructors

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

hashCode → int: The hash code for this object. [...]
read-only, inherited
runtimeType → Type: A representation of the runtime type of the object.

animate(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. [...]
chain(Animatable<double> parent) → Animatable<T>: Returns a new Animatable whose value is determined by first evaluating the given parent and then evaluating this object. [...]
evaluate(Animation<double> animation) → T: The current value of this object for the given Animation. [...]
transform(double t) → T: Returns the value of the object at point t. [...]
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]

toString() → String: Returns a string representation of this object.
