Learn Dagger 2 Dependency Injection in Kotlin with a beginner-friendly real-world example! In this video, we use a Car and Engine analogy to explain how Dagger handles dependencies using @Inject and @Component.
What you’ll learn:
What is Dependency Injection (DI)?
How to use @Inject for constructor injection
How @Component interfaces work in Dagger
Why Dagger is useful when Android doesn't support constructor injection in Activity or Fragment
Complete explanation of how Dagger creates object graphs automatically
This is perfect for Android developers preparing for interviews or learning clean architecture.
Code covered:
Car class with Engine dependency
