Well, so far in this course we have seen how to create your own lifecycle-aware components.

  val loadingState: LiveData<UiLoadingState>

  private val _loadingState = MutableLiveData<UiLoadingState>()
  val loadingState: LiveData<UiLoadingState>
    get() {
      return _loadingState
    }

  private val _loadingState = MutableLiveData<UiLoadingState>()
    get() {
      return _loadingState
    }
    _loadingState.value = UiLoadingState.Loading
  fun getRandomRecipe() {

    _loadingState.value = UiLoadingState.Loading

    viewModelScope.launch {
      recipeRepository.getRandomRecipe().collect { result ->
        _loadingState.value = UiLoadingState.NotLoading
        _recipeState.value = result
      }
    }
  }
  viewModel.loadingState.observe(this, Observer { uiLoadingState ->
      handleLoadingState(uiLoadingState)
  })
