Ref<T> class

Ref ~ Data reference

• Having problems with non immutable classes?
• have a few fields you will like to edit or change any where in your code?
• need raw global access in to a value in your code?

Well, your problem is solved. You can now reference your Object using the Ref class and easily set and get the value anytime and anywhere in your code. Ref helps to assign a key to your Object. Making it available globally in your code.

var data = Ref.of(#data).get;
Ref.of(#data).set(data);
Ref.of(#data).get = data}
Ref.create(data)

Properties

get ↔ T?

getter/setter pair

hashCode → int

no setter, override

hasListeners → bool

Whether any listeners are currently registered.

no setter, override

key ↔ Symbol

late, final

runtimeType → Type

A representation of the runtime type of the object.

no setter, override

Methods

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

override

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

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

override

removeListener(VoidCallback listener) → void

Remove a previously registered closure from the list of closures that are notified when the object changes.

override

set(T? data) → Ref<T>

toString() → String
