Got lateinit property mainPresenter has not been initialized in Kotlin

[lectricas]

hey, I have this code:

class MainActivity : MvpAppCompatActivity(), MainViewInterface, AnkoLogger {

    @InjectPresenter
    lateinit var mainPresenter: MainPresenter

    val recyclerView: RecyclerView by bindView(R.id.track_list)
    val fab: FloatingActionButton by bindView(R.id.fab)
    val cLayout: CoordinatorLayout by bindView(R.id.main_coordinator)

    val realm: Realm = Realm.getDefaultInstance()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        MyApplication.graph.inject(this)
        recyclerView.layoutManager = LinearLayoutManager(this)
        mainPresenter.loadAllTracks() //error here
    }

ViewState:

@StateStrategyType(value = AddToEndSingleStrategy::class) //not sure about this thing
interface MainViewInterface : MvpView {
    fun successLoadingTracks(tracks: List<Track>)
}

Presenter

@InjectViewState
class MainPresenter : MvpPresenter<MainViewInterface>() {

    fun loadAllTracks() {
        viewState.successLoadingTracks(ArrayList())
    }
}

And I get this error when trying to access presenter var. Kotlin plugin is up to date.

SOLUTION

forgot to include
kapt 'com.arello-mobile:moxy-compiler:0.4.2'

this thing. Now it's working.

Try 1+ library version ;-)

Also , this error might happen when you forgot to extend MoxyFragment \ Activity.

Also, try to Clean/Rebuild project - this works for me
