ProvidePresenter is called earlier than Lifecycle.Event.ON_CREATE

Hi guys, I'm using Moxy + Koin combo in some of my projects, and currently decoupling some lifecycle-aware code. For example, a separate LifecycleObserver for managing Koin scopes looked like a nice idea. However, it doesn't work because presenter (a scoped injection) is called before ON_CREATE event was fired (so no scope created yet). Maybe I'm doing something wrong?

A simple example:

class LifecycleAwareScope(
        lifecycle: Lifecycle,
        private val scopeName: String
) : LifecycleObserver, KoinComponent {
    init {
        lifecycle.addObserver(this)
    }

    private var mScope: Scope? = null

    @OnLifecycleEvent(Lifecycle.Event.ON_CREATE)
    fun createScope() {
        mScope = getKoin().createScope(scopeName)
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_STOP)
    fun closeScope() {
        mScope?.close()
    }
}

fun AppCompatActivity.addScope(scopeName: String) =
        LifecycleAwareScope(this.lifecycle, scopeName)

abstract class BaseActivity : MvpAppCompatActivity() {
    abstract val scopeName: String

    override fun onCreate(savedInstanceState: Bundle?) {
        this.addScope(scopeName)
        super.onCreate(savedInstanceState)
    }
    
    // rest of the code here
}

class MainActivity : BaseActivity(), MainActivityView {
    override val scopeName = Const.ACTIVITY_MAIN

    @InjectPresenter
    lateinit var presenter: MainActivityPresenter

    @ProvidePresenter
    fun providePresenter() = get<MainActivityPresenter>()

    // rest of the code here
}
