ReactiveSet<T> class
A reactive implementation of a list.
The ReactiveList class extends Reactive and implements ListMixin. It provides reactive capabilities to a standard list by tracking changes and automatically updating the UI when the list is modified.
Example usage:
final list = ReactiveList<int>([1, 2, 3]);
list.add(4);
print(list.value); // Output: [1, 2, 3, 4]

→ List<
Function> -
no setterinherited
-
notifier
→ ReactiveNotifier<
Set< T> > -
Returns a ReactiveNotifier object associated with this Reactive instance.
The ReactiveNotifier allows listening to changes in the reactive variable.

-
A representation of the runtime type of the object.
no setterinherited
- single → T
-
Checks that this iterable has only one element, and returns that element.
no setterinherited
-
value
↔ Set<
T> -
