Properties

animation → Animation?
Animation that hold value for this animation
no setter
animationBehavior ↔ AnimationBehavior
The behavior of the controller when AccessibilityFeatures.disableAnimations is true.
getter/setter pair
begin ↔ T?
The value this variable has at the beginning of the animation.
getter/setter pair
controller → AnimationController
AnimationController for this animation
no setter
curve → Curve
Curve for when the animation goes ahead
final
debugLabel → String?
A label that is used in the toString output. Intended to aid with identifying animation controller instances in debug output.
final
duration → Duration?
The length of time this animation should last.
final
end ↔ T?
The value this variable has at the end of the animation.
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
isAnimating → bool
Whether this animation is currently animating in either the forward or reverse direction.
no setter
isCompleted → bool
Whether this animation is stopped at the end.
no setter
isDismissed → bool
Whether this animation is stopped at the beginning.
no setter
lastElapsedDuration → Duration?
The amount of time that has passed between the time the animation started and the most recent tick of the animation.
no setter
progress ↔ double
The current progress of the animation.
getter/setter pair
reverseCurve → Curve?
Curve when the animation goes back
final
reverseDuration → Duration?
The length of time this animation should last when going in reverse.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
status → AnimationStatus
no setter
value → T?
The current value of the animation.
no setteroverride
velocity → double
The rate of change of value per second.
no setter
vsync → TickerProvider
final

Methods

addListener(Function 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.
animateBack(double target, {Duration? duration, Curve curve = Curves.linear}) → TickerFuture
Drives the animation from its current value to target.
animateTo(double target, {Duration? duration, Curve curve = Curves.linear}) → TickerFuture
Drives the animation from its current value to target.
animateWith(Simulation simulation) → TickerFuture
Drives the animation according to the given simulation.
dispose() → void
Release the resources used by this object. The object is no longer usable after this method is called.
fling({double velocity = 1.0, AnimationBehavior? animationBehavior}) → TickerFuture
Drives the animation with a critically damped spring (within lowerBound and upperBound) and initial velocity.
forward({double? from}) → TickerFuture
Starts running this animation forwards (towards the end).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Calls all the listeners.
removeListener(Function listener) → void
Stop calling the listener every time the value of the animation changes.
override
removeStatusListener(AnimationStatusListener listener) → void
Stops calling the listener every time the status of the animation changes.
repeat({double? min, double? max, bool reverse = false, Duration? period}) → TickerFuture
Starts running this animation in the forward direction, and restarts the animation when it completes.
reset() → void
Sets the controller's value to begin, stopping the animation (if in progress), and resetting to its beginning point, or dismissed state.
reverse({double? from}) → TickerFuture
Starts running this animation in reverse (towards the beginning).
start({double? from}) → TickerFuture
alias of forward
stop({bool canceled = true}) → void
Stops running this animation.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
