It is very connivent to use any DI framework when all the objects required are available in application. For example, I have two classes Logger, Service and class Middleware is dependent on these classes. class Logger() class Service() //this class requires Logger & Service object class Middleware(private val logger:Logger. private val service:Service) // middleware object val middleware = Middleware(Logger(),Service()) Dagger can build objects of Logger and Service classes by indicating @Inject annotation to all three classes internal class Logger @Inject constructor() internal class Service @Inject constructor() //this class requires Logger & Service object internal class Middleware @Inject constructor(private val logger:Logger.
