In work manager’s doWork function, what scope can we use to run a flow?

override suspend fun doWork(): Result {
    myFlow.onEach { }.launchIn(//What scope do we use here?)
}

I think

CoroutineWorker

handles this for you if you do something like the following:

override suspend fun doWork(): Result = myFlow.collect { }

CoroutineWorker

launches

doWork

in it's own scope but doesn't make that scope publically visible, so if you just return your flow I'm pretty sure

CoroutineWorker

should just handle it for you. Check out the code here: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-master-dev:work/workmanager-ktx/src/main/java/androidx/work/CoroutineWorker.kt;bpv=0;l=63

Why would one want to be aware of the used coroutine scope ?

You don't need launchIn. The launchIn changes the scope in which the Flow is emitting items. If launchIn is not specified, this scope is the same scope in which the Flow's 'collect' is called. When 'collect' is called within a 'suspend' fun, the scope is the calling/outer CoroutineScope.
