Adapter class

Adapters provide a mechanism to drive an animation from an arbitrary source. For example, synchronizing an animation with a scroll, controlling an animation with a slider input, or progressing an animation based on the time of day.

Adapters must expose an init method which accepts the AnimationController used by an Animate instance, and adds the logic to drive it from an external source by updating its value (0-1). See the included adapters for implementation examples.

Adapters should be immutable, so that they can be shared between animations.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

inherited

toString() → String

A string representation of this object.
