Create singleton object which implements 2 interfaces

Question

single<ObserveLifeCycleState> { Communicator( domain = get(), repositoryMessanger = get() ) }

single<NewMessageListener> { Communicator( domain = get(), repositoryMessanger = get() ) }

As you can see I am instantiating the same 2 objects because it implements both interfaces. But this creates 2 different objects. How can I do it with only one initialization?

Answer 1

 single {
        Communicator(
            domain = get(),
            repositoryMessanger = get()
        )
    }
    single {
        val communicator: Communicator = get()

        communicator as NewMessageListener
    }
