Why is it not recommended to put all dependencies in one component? How can dependencies be organized differently?

Putting all dependencies into one component in Dagger harms modularity, violates the single responsibility principle, increases compilation time, and complicates testing.

Other ways to organize dependencies:

• Feature/module separation: Each functional area or application module has its own component.
• Using subcomponents: A component can inherit dependencies from a parent component, allowing for a hierarchical structure.
• Using dependent components: A component can obtain dependencies from another component but does not inherit them.
• Creating lifecycle components: Components associated with the lifecycle of an Activity, Fragment, or View.

Example of using a Subcomponent:

// Parent component
@Singleton
@Component(modules = AppModule.class)
interface ApplicationComponent {
    ActivityComponent activityComponent();
    // ... other providers
}

// Subcomponent
@ActivityScope // Custom scope
@Subcomponent(modules = ActivityModule.class)
interface ActivityComponent {
    void inject(MyActivity activity);
    // ... other providers
}

// Modules
@Module
class AppModule {
    // Application-level providers
}

@Module
class ActivityModule {
    // Activity-level providers
}
