RxList<T> class

An observable list whose value is always unmodifiable.

Setting value compares element-by-element with the current list, so re-assigning an equal list does not rebuild watchers.

final items = RxList<String>([]);

items.value = ['a', 'b'];               // replace
items.update((list) => [...list, 'c']); // derive a new list
items.value[0] = 'x';                   // throws — the list is unmodifiable

Methods

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

inherited

dispose() → void

Discards any resources used by the object.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

removeListener(VoidCallback listener) → void

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

inherited

toString() → String

Always throws — see Rx.toString.

override

update(Iterable<T> updateFn(Iterable<T> value)) → void

Derives a new list from the current one and always notifies listeners.

Operators
