Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited

inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
removeStatusListener(DoughStatusCallback callback) → void
Removes a status listener.
start({Offset? origin, Offset? target}) → void
Begin squishing the dough. Sets isActive to true. Informs all status listeners that the status has changed to DoughStatus.started.
stop() → void
Stops squishing the Dough. Sets isActive to false. Informs all status listeners that the status has changed to DoughStatus.stopped. The Dough will snap back to the origin and its original shape.
toString() String
