Dependency injection with Koin uses module definitions to organize dependencies. Create modules like AppModule, NetworkModule, and feature modules, then start Koin in your Application class and inject dependencies into ViewModels and Android components using koinViewModel() in Compose or activity/fragment injection.

Koin supports scoped injections and ViewModel injection together. You can define scoped singletons within modules and inject ViewModels using parameterized dependencies, qualifiers, and get() calls to compose repositories and use cases for clean architecture.

Organize dependencies by creating separate modules for each concern—AppModule for application-level setup, NetworkModule for API clients, and feature modules like HomeModule for feature-specific repositories, use cases, and ViewModels wired together through Koin.

Parameterized ViewModels in Koin are defined within modules using scoped injections and get() dependencies. Compose repositories and use cases as constructor parameters, then inject using koinViewModel() in Compose or standard activity/fragment injection patterns.

Koin supports both Compose and traditional Android injection patterns. Use koinViewModel() for Compose and standard Koin injection in activities and fragments, enabling flexible wiring across different UI frameworks within the same modular architecture.
