TouchRippleController class

The class defines and manages states, listeners, a context and other values related to touch ripple, ensuring that each state exists uniquely within the controller.

See Also, An instance of this class can be referenced and accessed externally to attach or detach states or related values.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object notifies its listeners.
override
attach(TouchRippleEffect effect) → dynamic
Delegates the task of adding a touch ripple effect to this controller to ensure it can be reliably detached and disposed later./
attachByKey(String key, TouchRippleEffect effect) → dynamic
Delegates the task of adding a touch ripple effect to this controller to ensure it can be reliably detached and disposed late by a given key.
delegateFrom(TouchRippleController other) → dynamic
Delegates all states and context from a given controller to itself and removes all states from the given controller, ensuring that each state exists only once in the controller.
detach(TouchRippleEffect effect) → dynamic
Delegates the task of detaching and disposing of a touch ripple effect to ensure consistency with attach function.
detachByKey(String key) → dynamic
Delegates the task of detaching and disposing of a touch ripple effect to ensure consistency with attachByKey function by a given key.
dispose() → dynamic
Disposes all instances related the controller(e.g. TouchRippleEffect).
getEffectByKey<T extends TouchRippleEffect>(String key) → T?
Returns the ripple effect instance corresponding a given key.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Notifies that the state related to the controller has changed.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies.
override
toString() → String
A string representation of this object.
