ReverseAnimation class
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.
See also:
- Curve.flipped and FlippedCurve, which provide a similar effect but on Curves.
- CurvedAnimation, which can take separate curves for when the animation is going forward than for when it is going in reverse.

Methods
-
addListener(
VoidCallback listener) → void -
Calls the listener every time the value of the animation changes. [...]
override
-
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
-
removeListener(
VoidCallback listener) → void -
Stop calling the listener every time the value of the animation changes. [...]
override
-
toString(
) → String -
Returns a string representation of this object.
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
-
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

inherited
-
notifyStatusListeners(
AnimationStatus status) → void -
Calls all the status listeners. [...]
inherited
-
removeStatusListener(
AnimationStatusListener listener) → void -
Stops calling the listener every time the status of the animation changes. [...]
inherited
-
toStringDetails(
) → String -
Provides a string describing the status of this object, but not including
information about the object itself. [...]

Operators
-
operator ==(
dynamic other) → bool -
