baking-app-kotlin's Issues

add response and mappers

add domain layer and entity objects

data class ViewState over sealed class for ViewState

Is there any concern why using data class RecipeViewState instead of using sealed class RecipeViewState?

Equivalent to your existing code using sealed class

sealed class RecipeViewState : ViewState {
 object Loading : RecipeViewState()
 object Refreshing : RecipeViewState()
 data class LoadedRecipes(val recipes: List<RecipeModel>) : RecipeViewState()
 data class LikedRecipe(val recipe: RecipeModel) : RecipeViewState() // adding a new state for liked item
 data class Error(val error: String?, val errorEvent: ViewEvent<String>?, val isEmpty: Boolean) // Unavailable, No data or empty etc
}


// in Fragment 
// instead of:
    override fun render(state: RecipeViewState) {
        when {
            state.isDataUnavailable -> binding.renderEmptyState(state)
            state.isDataAvailableError -> binding.renderDataAvailableErrorState(state)
            state.isNoDataError -> binding.renderNoDataErrorState(state)
            state.isLoading -> binding.renderLoadingState()
            state.isRefreshing -> binding.renderRefreshState()
            else -> binding.renderSuccessState(state)
        }
    }

// modifed to:

    override fun render(state: RecipeViewState) {
        when (state) {
            is Error -> {  
                if (state.error != null) binding.renderNoDataErrorState(state)
                if (state.errorEvent != null) binding.renderDataAvailableErrorState(state)
                if (state.isEmpty) binding.renderEmptyState(state) 
            }
            Loading -> binding.renderLoadingState()
            Refreshing -> binding.renderRefreshState()
            is LikedRecipe -> binding.renderLikedState(state)
            is LoadedRecipes -> binding.renderSuccessState(state)
            // no else branch
        }
    }

Pros:

No need manually override every property/member of RecipeViewState using .copy with a new state
No else branch in override fun render
No need configuring a lot of function/method to determine state inside RecipeViewState, e.g for current approach: val *state: RecipeViewState get() = /* this.copy(isLoading = false, etc) */

Issue with Gradle Build

Hi Ezike, The current version of the project is using Bintray Repository and the AGP Version is also not compatible.
I'm currently using Android Studio Dolphin Canary.
