ReverseAnimation class Null safety

An animation that is the reverse of another animation.

If the parent animation is running forward from 0.0 to 1.0, this animation is running in reverse from 1.0 to 0.0.

Using a ReverseAnimation is different from simply using a Tween with a begin of 1.0 and an end of 0.0 because the tween does not change the status or direction of the animation.

Methods

addListener(VoidCallback listener) → void
Calls the listener every time the value of the animation changes. [...]
override
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.
override
didStopListening() → void
Called when the number of listeners changes from one to zero.
override
didUnregisterListener() → void
Calls didStopListening when an only remaining listener is unregistered, thus making the list empty. [...]
