Hi, I’m working with the application scope concept in my repositories to let some jobs running independent from the

viewModelScope

. In my scenario, I want to know when the job was done (success or failure) if the user didn’t leave the screen, and I want to let the view and view model free to be collected by the GC if the user leaves the screen. I’m reading this Medium Article from Manuel Vivo and I found following solution:

class Repository(
  private val externalScope: CoroutineScope,
  private val ioDispatcher: CoroutineDispatcher
) {
  suspend fun doWork(): Any { // Use a specific type in Result
    withContext(ioDispatcher) {
      doSomeOtherWork()
      return externalScope.async {
        // Exceptions are exposed when calling await, they will be
        // propagated in the coroutine that called doWork. Watch
        // out! They will be ignored if the calling context cancels.
        veryImportantOperation()
      }.await()
    }
  }
}

Is this solution the current one or do we have something new for this kind of scenario?

For us, the pattern is to make repositories contain only suspend functions, and to push up the knowledge of the

CoroutineScope

to the caller (like in the ViewModel).
