forkJoin3<A, B, C, T> static method
Merges the given Streams into a single Stream sequence by using the
combiner
function when all of the stream sequences emits their
last item.
Example
Rx.forkJoin3(
Stream.value('a'),
Stream.value('b'),
Stream.fromIterable(['c', 'd']),
(a, b, c) => a + b + c)
.listen(print); //prints 'abd'
Implementation
static Stream<T> forkJoin3<A, B, C, T>(Stream<A> streamA, Stream<B> streamB,
Stream<C> streamC, T Function(A a, B b, C c) combiner) =>
ForkJoinStream.combine3(streamA, streamB, streamC, combiner);
