RubberAnimationController class

Inheritance
Mixed in types

Constructors

RubberAnimationController({AnimationControllerValue? lowerBoundValue, AnimationControllerValue? halfBoundValue, AnimationControllerValue? upperBoundValue, bool dismissable = false, double? initialValue, Duration? duration, String? debugLabel, AnimationBehavior animationBehavior = AnimationBehavior.normal, AnimationPadding? padding, SpringDescription? springDescription, required TickerProvider vsync})
Creates an animation controller.

Properties

animationBehavior → AnimationBehavior
The behavior of the controller when AccessibilityFeatures.disableAnimations is true.
final
animationState ↔ ValueNotifier<AnimationState>
getter/setter pair
debugLabel → String?
A label that is used in the toString output. Intended to aid with identifying animation controller instances in debug output.
final
dismissable → bool
Tells if the bottomsheet has to remain closed after drag down
final
duration ↔ Duration?
The length of time this animation should last.
getter/setter pair
halfBound → double?
no setter
halfBoundValue ↔ AnimationControllerValue?
The value at which this animation is half expanded
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
height ← double
no getter
initialValue ↔ double?
Initial value of the controller in percentage
getter/setter pair
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 setterinherited
isDismissed → bool
Whether this animation is stopped at the beginning.
no setterinherited
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
lowerBound → double?
no setter
lowerBoundValue ↔ AnimationControllerValue
The value at which this animation is collapsed.
getter/setter pair
padding ↔ AnimationPadding
Pads the animation using value.clamp
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
springDescription ← dynamic
no getter
status → AnimationStatus
Tells if the animations is running(forward) or completed
no setteroverride
upperBound → double?
no setter
upperBoundValue ↔ AnimationControllerValue
The value at which this animation is expanded.
getter/setter pair
value ↔ double
The current value of the animation.
getter/setter pairoverride-getter
velocity → double
The rate of change of value per second.
no setter
view → Animation<double>
Returns an Animation<double> for this animation controller, so that a pointer to this object can be passed around without allowing users of that pointer to mutate the RubberAnimationController state.
no setter
visibility ↔ ValueNotifier<bool>
getter/setter pair

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
animateTo({double? from, required double to, Curve curve = Curves.easeOut}) → TickerFuture
animateWith(Simulation simulation) → TickerFuture
Drives the animation according to the given simulation.
clearListeners() → void
Removes all listeners added with addListener.
inherited
clearStatusListeners() → void
Removes all listeners added with addStatusListener.
inherited
collapse({double? from}) → TickerFuture
didRegisterListener() → void
This implementation ignores listener registrations.
inherited
didUnregisterListener() → void
This implementation ignores listener registrations.
inherited
dispose() → void
Release the resources used by this object. The object is no longer usable after this method is called.
override
drive<U>(Animatable<U> child) → Animation<U>
Chains a Tween (or CurveTween) to this Animation.
inherited
expand({double? from}) → TickerFuture
fling(double? from, double? to, {double velocity = 1.0, AnimationBehavior? animationBehavior}) → TickerFuture
getBoundFromState(AnimationState state) → double?
halfExpand({double? from}) → TickerFuture
launchTo(double from, double? to, {double velocity = 1.0, AnimationBehavior? animationBehavior}) → TickerFuture
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Calls all the listeners.
inherited
notifyStatusListeners(AnimationStatus status) → void
Calls all the status listeners.
inherited
pixelValuesToPercentage() → void
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
reset() → void
Sets the controller's value to initialValue or lowerBound, stopping the animation (if in progress), and resetting to its beginning point, or collapsed state.
resync(TickerProvider vsync) → void
Recreates the Ticker with the new TickerProvider.
setVisibility(bool show) → void
stop({bool canceled = true}) → void
Stops running this animation.
toString() → String
A string representation of this object.
inherited
toStringDetails() → String
Provides a string describing the status of this object, but not including information about the object itself.
override

Operators

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