I have a function like this:

fun getNumbers2(input: Int): Flow<Int> = callbackFlow {
    for (i in 1..5) {
        send(i + input)
        delay(1000)
    }
    close()
}

I want that Flow to return another Flow from inside a Flow function. How can I achieve something like the following snippet?

fun getNumbers1(): Flow<Int> = callbackFlow {
    val input = 2
    send(input)
    return getNumbers2(input) // do we have any resumeWith() or continueWith() function in Kotlin Flow??
}

The expectation is to achieve a coroutine like this:

GlobalScope.launch(Dispatchers.IO) {
    getNumbers1().collect {
        // it should be able to print results from getNumbers2() as well
        println("Result: $it")
    }
}

I don’t want to create a Flow chain like this, because it does not suit my case:

GlobalScope.launch(Dispatchers.IO) {
    getNumbers1().flatMapMerge { getNumbers2(it) }.collect {
        println("Result: $it")
    }
}

Thanks in advance.
