    This is about a tool / library. Tools and libraries will change over time. Most of the things you learn in school won't change. If you are in engineering school you are not there to learn how to make a hole in metal with one particular kind of machine. You don't need a professor fot that. You are there to know why, when and where you have to make that hole.

    @@RaajKanchan bro, you are getting it wrong. This is not something to be passed usong dagger. This data which should be passed either from activity to another Activity or else load from network for that particular screen. Dagger should be used to inject those dependencies which screen requires but doesn't care how it is created. So, as per my understanding your usecase is incorrect.

    I think we should use @InstallIn(ViewModelComponent::class.java) since the repository lives inside a ViewModel, in the meantime that we inject the repository inside the ViewModel, hilt will then delete this repository instance when the ViewModel is cleared (onCleared is called, ViewModel is destroyed because its activity/fragment does not need it anymore). If we do it with the SingletonComponent it will be tied up with the Application class you created, and hence, the repository instance will outlive the ViewModel. Another way of not using @Named could be to use @Qualifiers which can be more verbose on for example creating two different okHttp clients Great video Philipp, it contains a lot of excellent suggestions !
