How to properly use Dagger scopes in an MVVM project?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I'm creating a simple app and I want to use Dagger in it (I'm a complete beginner in Dagger). It has three layers: View, ViewModel, and Repository.
Naturally each one of the classes in these layers have different dependencies and different scopes. Take a look at this sample:
class SongsFragment : Fragment() {
val viewModel: SongsViewModel
}
class SongsViewModel(val songRepository: SongRepository) : ViewModel() {
}
class SongRepository(val songDao: SongDao) {
}
SongsViewModel instance should exist as long as SongsFragment exist and SongRepository instance should exist as long as SongsViewModel instance exists. (Correct me if it's not a good practice)
I'd appreciate a simple example of how to use modules, components (and subcomponents if necessary), and scopes to achieve this goal.

Thanks but your article uses classes in dagger-android package and since I'm new to Dagger, I don't want to use them for now.
