Learn Dagger 2 Dependency Injection in Android. In this video - learn how to define component dependencies. Component can use other components to provide the required dependencies. These dependent components need to be declared inside @component annotation to let dagger know about the dependent components. Using this dependency array, dagger uses the objects provided by other components.

If you are using factory method or builder method to create the component then you need to explicitly pass the reference of dependent objects i.e. while creating the component you need to pass the required dependent objects so that dagger can create the component for you.
