combine2<A, B, R> method

ForkJoinStream<dynamic, R> combine2 <A, B, R>(
  1. Stream<A> streamOne,
  2. Stream<B> streamTwo,
  3. R combiner(
    1. A a,
    2. B b

Constructs a Stream that awaits the last values the provided Streams, then calls the combiner to emit an event of type R. After this event, the Stream closes.
