AppModule.java

@Module
public class AppModule {
    public static final String BASE_URL = "https://api.github.com/";

    @Provides
    @Singleton
    GithubApiService provideGithubApiService() {
        return new Retrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create())
                .baseUrl(BASE_URL)
                .build()
                .create(GithubApiService.class);
    }

    @Provides
    @Singleton
    IssueRepository provideIssueRepository(IssueRepositoryImpl repository) {
        return repository;
    }

    @Provides
    ViewModel provideListIssuesViewModel(ListIssuesViewModel viewModel) {
        return viewModel;
    }

    @Provides
    ViewModelProvider.Factory provideListIssuesViewModelFactory(
            ViewModelFactory factory
    ) {
        return factory;
    }

}
