I have the following use case:
My function returns a flow.. for simplicity lets say it returns Flow<Int>

In this function I have an api call which also returns a flow

What is the best way to give result back to the caller?

Sample code in thread

[Ruben Quadros]

fun apiCall(): Flow<Int> = flow {
    delay(2000) // some network call
    emit(3)
}

fun myFunc(): Flow<Int> = flow {
    emit(1) //denote loading
    apiCall() 
    
    //is the only way collecting here and emitting again?

  // apiCall().collect { emit(it) }
}

call site

myFunc().collect {
    //do something with each result
}

Why does apiCall return a flow of one element? One-shot calls are way easier to manipulate as simple suspend functions

[Joffrey]

If you really really want a flow from the API call, you could use emitAll I guess, but I would really reconsider the apiCall function first

understood.. making it a one-shot call will be better 👍
