Я получаю странную ошибку, когда я запускаю MainActivity

Это мой класс MainActivity
:
class MainActivity : LifecycleActivity(), HasSupportFragmentInjector {
lateinit var dispatchingAndroidInjector: DispatchingAndroidInjector<Fragment>
@Inject set
lateinit var navigationController: NavigationController
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.main_activity)
if (savedInstanceState == null) {
navigationController.navigateToSearch()
}
}
override fun supportFragmentInjector(): AndroidInjector<Fragment> {
return dispatchingAndroidInjector
}
}
Ошибка указывает, что параметр savedInstanceState
имеет значение null, если он указан как savedInstanceState
; но он является savedInstanceState: Bundle?
(savedInstanceState: Bundle?
), а метод onCreate()
помечен как @Nullable
в источнике.
Я не встречал эту ошибку ни в одном из моих других проектов Котлина. Я использую Kotlin версии 1.1.2-5; и имела ту же ошибку с 1.1.2-3.
