I have like 2 flows and I want to observe their changes with flatMapLatest, if either of them emit new value, I want to trigger some action, but how can I observe on 2 flows , should I combine them ? how can I do so

You can use merge(flow1, flow2)

[gildor]

or combine(flow1, …) if you need result of both streams

[Vivek Sharma]

when I was using flatMapLatest and inside lambda, I was receiving flow and flatMapLatest was returning that flow
, but when I use combine, this will emit Flow<Flow<>> , so is there a way to achieve like flatMapLatest

[gildor]

Make sure that you have correct implementation of combine lambda

[gildor]

If you want to return Flow from lambda you then should add some additional operators like flattenMerge, depends on how you expect it should work

I did one thing, I used like this

val someStateFlow = flow1.combine(flow2) { a, b ->
    recievingFlowFromRepository().first()
}.stateIn(...)

I used first() as I think I will not receive more values (usecase here is getting data from network) and then let the combine convert it to flow
