Listenable.merge constructor

Listenable.merge(
  1. Iterable<Listenable?> listenables
)

Return a Listenable that triggers when any of the given Listenables themselves trigger.

Once the factory is called, items must not be added or removed from the iterable. Doing so will lead to memory leaks or exceptions.

The iterable may contain nulls; they are ignored.

Implementation

factory Listenable.merge(Iterable<Listenable?> listenables) = _MergingListenable;
