Hi guys. Is there an equivalent to Flow.withLatestFrom(other: Flow<B>, transform: suspend (A,B) -> R) that takes several other Flows? I need values emitted downstream only when source flow changes.

It doesn't do several automatically but shouldn't be hard to chain.

It seems that this operator emits values every time there is a new value from one of the combined flow. Correct me if I'm wrong

do you want to wait until all of them emit? maybe zip is what you’re after?

@ubu Yes

If you have a two flows.
• a, b, c, d
• 1, 2, 3, 4
It'll emit something like, a1, a2, b2, c2, etc.
What do you want to emit?

I will repost this question in few minutes.

@Dominaezzz, thanks for taking interest!
