将Dispatcher.Main与delay（）一起使用是个好主意吗？

Question

fetchData() is suspendCoroutine function, so it is implemented on other thread.

viewModelScope is bound to Dispatchers.Main : this should be used only for interacting with the UI and performing quick work.

So should I have delay() in Dispatcher.Main or should I move out it?

fun loadData() {
    viewModelScope.launch {
      delay(START_DELAY)
      when (val result = fetchData()) {
        is Response.Success<IData> -> {}
        is Response.Failure -> {}
      }
    }
  }


fun fetchData(){
    return suspendCoroutine { cont ->}
}

Answer 1

Answer is it can stay, delay will not hurt Main thread, it will not block it. This coroutine inside Main Dispatcher will be suspended, while other coroutines inside Main will continue to run.
