@Scope
@Retention(CLASS)
public @interface ViewModelScoped

Scope annotation for bindings that should exist for the life of a a single ViewModel.

Use this scope annotation when you want to define a dependency in the ViewModelComponent for which a single instance will be provided across all other dependencies for a single HiltViewModel-annotated ViewModel. Other ViewModels that request the scoped dependency will receive a different instance. For sharing the same instance of a dependency across all ViewModels use a scope from one of the parent components of dagger.hilt.android.components.ViewModelComponent, such as Singleton or ActivityRetainedScoped.

For example:

 @Module
 @InstallIn(ViewModelComponent.class)
 public final class ViewModelMovieModule {
     @Provides
     @ViewModelScoped
     public static MovieRepository provideRepo(SavedStateHandle handle) {
         return new MovieRepository(handle.getString("movie-id"));
     }
 }

 public final class MovieDetailFetcher {
     @Inject MovieDetailFetcher(MovieRepository movieRepo) {
         // ...
     }
 }

 public final class MoviePosterFetcher {
     @Inject MoviePosterFetcher(MovieRepository movieRepo) {
         // ...
     }
 }

 @HiltViewModel
 public class MovieViewModel extends ViewModel {
     @Inject
     public MovieViewModel(MovieDetailFetcher detailFetcher, MoviePosterFetcher posterFetcher) {
         // Both detailFetcher and posterFetcher will contain the same instance of
         // the MovieRepository.
     }
 }
