What ready-made components with a specific scope are available in Dagger Hilt, and how can a module be added to this component?

Dagger Hilt provides several ready-made components with specific scopes that correspond to the lifecycle of Android components:

• SingletonComponent — scope for the entire application.
• ActivityComponent — scope for the Activity lifecycle.
• FragmentComponent — scope for the Fragment lifecycle.
• ViewModelComponent — scope for the ViewModel lifecycle.
• ServiceComponent — scope for the Service lifecycle.
• ViewComponent — scope for the View lifecycle.

To add a module to a component, create a class annotated with @Module and specify the desired component in @InstallIn. For example:

@Module
@InstallIn(ActivityComponent::class)
object MyActivityModule {
    @Provides
    fun provideSomeDependency(): SomeDependency {
        return SomeDependency()
    }
}

Thus, dependencies from this module will be available within the lifecycle of the Activity.
