Я работаю над применением многомодульной структуры с помощью dagger к своему проекту. Я получаю ошибку во время работы над ViewModelFactory . Что я на самом деле хочу сделать для ViewModelFactory, так это следующее: я хочу, чтобы app module он предоставлял ViewModelFactory и feature modules использовал его.

Ошибка, с которой я столкнулся здесь, заключается в:

 C:UsersCloudDesktopdaggerMultiModuleSampleDaggerMultiModuleSamplefeature-onebuildtmpkapt3stubsdebugcomemrememilfeature_onediFeatureOneComponent.java:8: error: [Dagger/MissingBinding] androidx.lifecycle.ViewModelProvider.Factory cannot be provided without an @Provides-annotated method. public abstract interface FeatureOneComponent {  ^  androidx.lifecycle.ViewModelProvider.Factory is injected at  com.emrememil.feature_one.view.FeatureOneActivity.viewModelFactory  com.emrememil.feature_one.view.FeatureOneActivity is injected at  com.emrememil.feature_one.di.FeatureOneComponent.inject(com.emrememil.feature_one.view.FeatureOneActivity)  

AppComponent.kt

ViewModelModule.kt

FeatureOneComponent.kt

 @FeatureScope @Component(  dependencies = [MainComponent::class],  modules = [FeatureOneModule::class] ) interface FeatureOneComponent {  fun inject(activity: FeatureOneActivity) }  

FeatureOneActivity.kt
