I'm having issues injecting a scoped dependency into my viewmodel and creating the viewmodel.

class Cache(sess: SessionManager)

class MyViewModel(cache: Cache): ViewModel {}

module {
   single { SessionManager() }

   scope(named("userSession")) {
       scoped { Cache(get()) }

       viewModel { MyViewModel(get()) }
   }
} 

class MyFragment: Fragment() {
    private val myVm: MyViewModel by viewModel()
}

The above is the structure of my koin setup but when I run this it crashes my app with the error;

Caused by: org.koin.core.error.NoBeanDefFoundException: No definition found for class:'com.play.MyViewModel'. Check your definitions!

Please what could I be doing wrongly here?

private val myVm: MyViewModel by viewModel() is requesting your viewModel from global space, but you defined it in a scope

[arnaud.giuliani]

you must query it from your userSession scope

[arnaud.giuliani]

in your Fragment you need to retrieve your scope:

[arnaud.giuliani]

val userSession : Scope by lazy { getKoin().getOrCreateScope( ... )}

[arnaud.giuliani]

and then, use private val myVm: MyViewModel by userSession.viewModel()

Thanks! I tried this but then there are several parameters the viewModel method requires which I have no idea how to obtain. You have any example of this?

[chi]

Ok, I was able to get the viewmodel with this;

private val viewModel: MyViewModel by userScopeSession.viewModel(owner = { ViewModelOwner(viewModelStore) })

[arnaud.giuliani]

owner can be your fragment too

[chi]

I think that has been changed.
