Hi All, I had a code looks like below ```fun main(...

# coroutines

Hi All, I had a code looks like below

fun main() {
    viewModelScope.launch {
        doA()
        //call api with Flow as the return type
    }
}

suspend fun doA() {
    viewModelScope.async { doB() }.await()
}

suspend fun doB() {
    //Do logic here, eventually will call line below
    viewModelScope.launch { doC() }
}

suspend fun doC() {
    //call api with Flow as the return type
}

What I want to achieve from the code above is to wait for the doA() function to finished and then continue to call the API, but when I tried to run the code, the doA() is executed first but it continue to call the API rather than waiting for the doA() to finish. Is there's something wrong with the code? Yes, the code is quite bad, I still kind a new with the Coroutine, thanks for helping, really appreciate it

Do you want to wait to finish the doA()?

[bobby]

yap, that's what I want to achieve here

[Naoki Hidaka]

How about this?

fun main() {
    viewModelScope.launch {
        async { doA() }.await
    }
}

what's the difference between your suggestion with code below?

fun main() {
    viewModelScope.launch {
        async { doB() }.await()
    }
}

[Naoki Hidaka]

No differene

[bobby]

ok than, I'll try

I had tried your solution but it didn't working like what I want to achieve, the code below doA() which is the call API still run without waiting the doA() finish. I think because at the doB() I created new scope that I think works separate with the scope in main()
