A, B, C, D, R> method
Creates a Stream that emits when the source stream emits, combining the latest values from the five streams using the provided function.
If any of latestFromStreams has not emitted any values, this stream will not emit either.
Stream.fromIterable([1, 2]) .withLatestFrom4( Stream.fromIterable([2, 3]), Stream.fromIterable([3, 4]), Stream.fromIterable([4, 5]), Stream.fromIterable([5, 6]), (int a, int b, int c, int d, int e) => a + b + c + d + e, ) .listen(print); // prints 16 (due to the async nature of streams)
Stream<R> withLatestFrom4<A, B, C, D, R>( Stream<A> latestFromStream1, Stream<B> latestFromStream2, Stream<C> latestFromStream3, Stream<D> latestFromStream4, R Function(T t, A a, B b, C c, D d) fn, ) => transform(WithLatestFromStreamTransformer.with4( latestFromStream1, latestFromStream2, latestFromStream3, latestFromStream4, fn, ));
