An animation of doubles that tracks the mean of two other animations.

The status of this animation is the status of the right animation if it is moving, and the left animation otherwise.

The value of this animation is the double that represents the mean value of the values of the left and right animations.

Methods

addListener(VoidCallback listener) → void
Calls the listener every time the value of the animation changes. [...]
inherited
addStatusListener(AnimationStatusListener listener) → void
Calls listener every time the status of the animation changes. [...]
inherited
didRegisterListener() → void
Calls didStartListening every time a registration of a listener causes an empty list of listeners to become non-empty. [...]
inherited
didStartListening() → void
Called when the number of listeners changes from zero to one.
inherited
didStopListening() → void
Called when the number of listeners changes from one to zero.
inherited
didUnregisterListener() → void
Calls didStopListening when an only remaining listener is unregistered, thus making the list empty. [...]
inherited
drive<U>(Animatable<U> child) → Animation<U>
Chains a Tween (or CurveTween) to this Animation. [...]
@optionalTypeArgs, inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
notifyListeners() → void
Calls all the listeners. [...]
inherited
notifyStatusListeners(AnimationStatus status) → void
Calls all the status listeners. [...]
inherited
removeListener(VoidCallback listener) → void
Stop calling the listener every time the value of the animation changes. [...]
inherited
removeStatusListener(AnimationStatusListener listener) → void
Stops calling the listener every time the status of the animation changes. [...]
inherited
toString() → String
Returns a string representation of this object.
inherited
toStringDetails() → String
