I am using Hilt and I have a module setup like this:

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

  ...

  @Binds
  @IntoMap
  @IntKey(1)
  @Reusable
  internal abstract fun bindsFirstProvider(impl: FirstProvider) : Provider

  @Binds
  @IntoMap
  @IntKey(2)
  @Reusable
  internal abstract fun bindsSecondProvider(impl: SecondProvider) : Provider

}

I am trying to inject the map into a class like this:

@Reusable
@OptIn(ExperimentalCoroutinesApi::class)
internal class ProviderService @Inject constructor(
  private val providerMap: Map<Int, Provider>,
)

I am getting this compile time error:

error: [Dagger/MissingBinding] java.util.Map<java.lang.Integer,? extends com.example.Provider> cannot be provided without an @Provides-annotated method.

What am I missing to get this to work?

internal class ProviderService @Inject constructor(
private val providerMap: Map<Int, @JvmSurpressWildCards Provider>,
)

Thanks so much @FunkyMuse that makes sense!
