Hello! Can anyone tell me if there's a neater way of doing this? I'm trying to essentially run some code after a specified delay, but I want to handle the case the function is called before it's actually finished executing.

private var job: Job? = null
    private fun scheduleJob() {
        job?.cancel()
        job = flow<Void> {
            delay(mySpecifiDelay)
            doWork()
        }.launchIn(CoroutineScope(coroutineDispatcher))
    }

Might as well be using GlobalScope there.

[Dominaezzz]

Also, it doesn't look like you need a flow here, you can just launch .

[Dominaezzz]

To be clear, don't use GlobalScope , just store your CoroutineScope somewhere and re-use it.

Brain fart, good point, I can just do

private fun scheduleJob() {
        job?.cancel()
        job = CoroutineScope(coroutineDispatcher).launch {
            delay(mySpecifiDelay)
            doWork()
        }
    }

Yeah I've been going back and forth on the best way of handling scopes, I'm injecting the coroutineDispatcher and I can never decide which pattern I prefer when it comes to getting hold of a scope

[Dominaezzz]

Well, if you're going to re-create it each time, just use GlobalScope . It's the same thing but less allocations.

Instead of injecting Dispatchers, I inject CoroutineScopes.

It has been helping me much. Including having it in memory
