SimAnimationController<T> class
A FluxAnimation driven by a Sim.
This is the workhorse: it takes a generic simulation (spring, friction, gravity, anything) and drives it with a Ticker. Unlike Flutter's AnimationController, the simulation owns the value — there's no artificial 0.0–1.0 range.

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
-
clearListeners(
) → void -
Removes all listeners added with addListener.
inherited
-
clearStatusListeners(
) → void -
Removes all listeners added with addStatusListener.
inherited
-
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
-
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
-
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
-
start(
) → TickerFuture - Start the animation.
-
stop(
{bool canceled = false}) → void - Stop the animation, optionally marking it as cancelled.
-
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.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
