join5<A, B, C, D, E, R> static method

ForkJoinStream<dynamic, R> join5<A, B, C, D, E, R>(
  1. Stream<A> streamA,
  2. Stream<B> streamB,
  3. Stream<C> streamC,
  4. Stream<D> streamD,
  5. Stream<E> streamE,
  6. R combiner(
    1. A a,
    2. B b,
    3. C c,
    4. D d,
    5. E e,
    ),
)

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.
