Cannot scope child components dependencies with parent component's scope using Provides

[evant]

That error is expected, you can only used scoped provides in a component that's scopped in the same scope, in your example, you should move : StockMeHttpClientProvider to SingletonComponent

@evant But i am creating a SingletonComponent so that i can scope any dependency to be singleton and SingletonComponent exists in a lower level module and why is it possible to only scope non Provides dependencies to parent Component?

[evant]

@Provides means 'this component is creating the dependency', if it's scoped the component has to have the same scope to make sure it has the correct lifetime. You could re-recreate CoreDataLayerComponent multiple times and you'd want your singleton to live longer than that, so it can't be the owner.

@evant Okay, got it. But i think it be good to have something through which we can scope our higher level module's dependencies to lower level module's but are not provided by the higher level module's scope but want to scope it to lower level module's scope. So that the lower level doesn't become cluttered with all the providers in my case Singletons.
Right now to scope a dependency to a common Component we have to we have two different direction either to put the SIngletonComponent in the app module for @Provides and for @Inject in lower level modules.
something like InstallIn in hilt.
If there exits some other method for achieving this, Please let me know.

[evant]

Current recommendation for this is put a SingletonComponent interface in your base module and an impl of it in your app.

@evant I tried it but getting the @Provides with scope: `in`.stock.core.di.ApplicationScope cannot be provided in an unscoped component. Is it possible in future tohave something where dependencies can be marked with @Provides outside of component like Hilt
