value property Null safety

T value

The Listenable stored in this property.

A representation of the current value of the Listenable is stored in the restoration data. During state restoration, the Listenable returned by this getter will be restored to the state it had when the restoration data the property is getting restored from was collected.

The value can only be accessed after the property has been registered with a RestorationMixin by calling RestorationMixin.registerForRestoration.

Implementation

T get value {
  assert(isRegistered);
  return _value!;
}
