问题 I have built a Dynamic feature module sample with Fragments, sub components and dependent components based on plaid app, if you wish to check out here is the link. Now, i'm trying to convert it to Dagger Hilt using the official android document. In core module which is the library module, app module and dynamic feature modules depend on @Singleton @Component(modules = [CoreModule::class]) interface CoreComponent { /* Provision methods to provide dependencies below to components that depends
