How to Return LiveData from Repository

Question

I just can\'t see how to chain LiveData from Repo to VM, so I have tried to boil this down to the most simple of example!:

Fragment

Answer 1

No need to change MutableLiveData inside ViewModel. Try to pass whatever Repository send to View. Check below

class LoginViewModel : ViewModel() {

    private val firestoreRepository : FirestoreRepository = FirestoreRepository()

    fun getCurrentName(): MutableLiveData {
        return firestoreRepository.getCurrentName()
    }

    fun changeText() {
        firestoreRepository.changeText()
    }
}

And also your FirestoreRepository

class FirestoreRepository {

    private val mCurrentName = MutableLiveData()

    fun getCurrentName(): MutableLiveData {
        return mCurrentName
    }

    fun changeText() {
        mCurrentName.value = "Button Clicked!!"
    }
}
