SpinnerController class
A controller used to programmatically trigger the spinning wheel.
It is a ChangeNotifier: listen to it (e.g. with a ListenableBuilder)
to rebuild when isSpinning or lastResult change. If you add listeners,
call dispose when you no longer need the controller.

Constructors
Properties
- hashCode → int
-
The hash code for this object.

- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
- isAttached → bool
-
Whether a SpinnerWheel is currently using this controller.
no setter
- isSpinning → bool
-
Whether the wheel is currently spinning.

-
The result of the most recent finished spin, if any.

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
attachState(
SpinnerWheelState state) → void - Attaches the controller to a SpinnerWheelState. This is called internally by the SpinnerWheel.
-
detachState(
SpinnerWheelState state) → void -
Detaches the controller from
state, if it is the one attached. This is called internally when the SpinnerWheel is disposed or switches to a different controller. -
dispose(
) → void -
Discards any resources used by the object.
override
-
handleSpinFinished(
WheelSpinResult? result) → void -
Called internally by the SpinnerWheel when a spin ends, with its
result, or null if the spin was abandoned. -
handleSpinStarted(
) → void - Called internally by the SpinnerWheel when a spin starts.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
spinTo(
int index) → Future< WheelSpinResult?> -
Spins the wheel so that it lands on the segment at
index, ignoring probabilities. Useful when the result is decided elsewhere, e.g. by a server. -
startSpin(
) → Future< WheelSpinResult?> - Triggers the wheel to start spinning based on the configured segments and logic.
-
stop(
) → void - Brings a spinning wheel to a quick stop.
-
toString(
) → String -
A string representation of this object.

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