hello i saw other way @Module @InstallIn(SingletonComponent::class) object RepositoriesModule {

@Provides @Singleton fun provideNewsRepository( apiService: NewsApiService ): NewsRepository = NewsRepositoryImpl ( apiService) } -

class NewsRepositoryImpl ( private val apiService: NewsApiService

) : NewsRepository {....

VS

@Module @InstallIn(SingletonComponent::class) abstract class RepositoryModule {

@Binds abstract fun bindNewsRepository( impl: NewsRepositoryImpl ): NewsRepository } -

class NewsRepositoryImpl @Inject constructor( private val apiService: NewsApiService

) : NewsRepository {....

Basically use bind for repos and singleton only for retrofit room

why not this way?
