Constructors

animValue → double: Current animation progress value (0.0 to 1.0) after applying curve.
no setter
callback ↔ VoidCallback?: A callback to be invoked when conditions are met.
getter/setter pair
context → TouchScaleContext: Holds configuration and context needed for animation.
final
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
isRejectable ↔ bool: Indicates whether the gesture is currently rejectable.
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

accept() → void: Accepts the gesture and notifies listeners of the current animation status.
addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
dispose() → void: Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
forward() → void: Starts the forward animation, initializing controllers if necessary. When completed and not rejectable, automatically reverses the animation.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
reject() → void: Rejects the gesture and starts reversing the animation.
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
toString() → String: A string representation of this object.
inherited
tryCall() → void: Calls callback if the gesture is not rejectable, then clears it.
