Android Viewmodel savestate using dagger2

Question

I am using ViewModel savestate handle in my app, I inject ViewModel using the dagger, So I used AssistInject to inject SaveStateHandle in to viewmodel. Everything works fine for me, But one thing I need to know is that I need to pass the bundle which I received in the fragment to the savestatehandle. So in my fragment module, I provide the method injection for the fragment/activity which am using and get the arguments/intent and so while using the scope I can get the same bundle in the viewmodel factory.

Example: Dagger Fragment/Activity module class

@FragmentScope
@ContributesAndroidInjector(modules = [TestingModule::class])
abstract fun bindTestingScreenFragment(): TestingScreen

TestingModule::class

@Module(includes = [TestingModule.TestingAbstractModule::class])
class TestingModule {

    @Provides
    fun provideDefaultArgs(testingScreen: TestingScreen): Bundle? = testingScreen.arguments

    @Module
    abstract class TestingAbstractModule {
        @Binds
        abstract fun bindTestingScreen(testingScreen: TestingScreen): SavedStateRegistryOwner
    }
}

The doubt which i had is in the provideDefaultArgs method i inject the screen which i am currently injecting for, So how this works without the circular dependency error. does anyone have any idea on this ?
