Correct implementation of Swipe-to-Refresh with LiveData.

UserListViewModel.kt

class UserListViewModel @Inject constructor(private val userRepository: UserRepository) : ViewModel() {

    private val reloadTrigger = MutableLiveData<Boolean>()
    private val users: LiveData<List<UserModel>> = Transformations.switchMap(reloadTrigger) {
        userRepository.getUsers()
    }

    init {
        refreshUsers()
    }

    fun getUsers(): LiveData<List<UserModel>> = users

    fun refreshUsers() {
        reloadTrigger.value = true
    }
}
