Hi. I have to clear db when exit fragment. I am creating a coroutine to clear db table inside viewmodel onCleared. As you can see i am not using viewModelScope because my table will not be cleared and coroutine will be cancelled. Do you think its fine to use CoroutineScope here?

Add a scope to your

repository

by inheriting from

: CoroutineScope by MainScope()

, then you can

launch

from within your

repository

instead of from outside it

I douldn't do that. You are exposing a buch of stuff then. For example you can close your repository now from the outside 😉

If that is of concern, then better to add a

private val coroutineScope = CoroutineScope(SupervisorJob() + Dispatchers.Main)

and use

coroutineScope.launch

I have a confusion. Will this coroutineScope leak if app closes?

if it doesn’t leak while the app is running, it will not leak when the app is closed.

So for example if i create a coroutine in repo and then i exit from screen & my coroutine is still running. Anything bad in that?

Nope. Assuming that your coroutine will come to a stop eventually..

It creates a new scope inside ViewModel and does not cancel itself, if it’s not finishing the job before the ViewModel gets cleared then the ViewModel can’t be garbage collected and a leak will occur. Is this a correct statement in the above context?

It creates a new scope inside ViewModel

No one has talked about creating a scope in a ViewModel.
