With Flow what is the "nicest" way to chain two network requests where the second depend on data from the first?

a

flatMap

? Although network requests would usually return just a single value so maybe you can just use

suspend fun

?

need to mull it over some more. I have a working solution which collects the first flow, requests the second data and then emits a combined result. but it doesn't feel that neat.

Well, again if it’s just one value then simple

val firstResponse = api.firstRequest()
return api.secondRequest(firstResponse.id)

would work fine. If you need flows for some reason, then I think

api.firstRequest()
  .flatMap { api.secondRequest(it.id) }

is the most idiomatic way

So I have two repositories, each fetching some data. I have a useCase which integrates with each repository to get this data. So essentially the usecase is handline two flows and needs to merge that data into one flow in a VM. If that makes sense?

ah, if you can make both requests in parallel then you might want

combine(flow1, flow2) { result1, result2 -> }

your question is the same with me above. flow B will depend on flow A at some point in future. You could view my issue at here, it solved. https://github.com/Kotlin/kotlinx.coroutines/issues/2548
