I'm building an app following an MVP pattern where I create each presenter using Dagger2 and all is well.

I went with Firebase and I noticed that in each of my presenters, I have the same dependencies

Database
Database Refrence
FirebaseAuth
FirebaseAuth.AuthStateListener
FirebaseUser

As well as all the listeners and call backs. Now, im creating a user creation flow and in each of my presenters that will be reused for a settings configuration down the road.

My problem is that I cant quite wrap my head around injecting these references, because the state changes as the user uses my app. There wont be a FirebaseUser upon first login, so im unsure how Dagger2 would update this dependency, or insure the proper callback listeners are engaged.

Any tips?

you need to work this out by using Scopes; do you need a sample ? – Jileshl Jul 18 '17 at 08:17
