This commit refactors how `ScreenUiState` is produced in `QuizScreenViewModel` by extracting the logic into a private `screenUiState` function that combines various flows. It also introduces `Result` sealed interface and `asResult()` Flow extension for handling asynchronous operations. Additionally, lint baseline files have been added to all modules and a Detekt configuration file for the `ui:quiz` module.
Key changes:
- **ViewModel Refactoring (`ui:quiz` module):**
- Introduced `Result.kt` with a sealed interface for `Success`, `Error`, and `Loading` states, along with an `asResult()` extension function for `Flow` to wrap emissions in `Result`.
- In `QuizScreenViewModel.kt`:
- The `quiz` state flow now uses `asResult()` and maps the `Result` to `QuizUiState`, handling potential error states by defaulting to `QuizUiState.Loading` (actual error UI handling is noted as a TODO).
- The logic for combining flows to produce `ScreenUiState` has been extracted into a new private function `screenUiState()`. This function takes the necessary flows as parameters and returns a `Flow<ScreenUiState>`.
- The `uiState` flow now uses this new `screenUiState()` function for its production.
- **Lint and Detekt Configuration:**
- Added `lint-baseline.xml` files to the following modules to establish a baseline for lint warnings:
- `app`
- `core/designsystem`
- `core/network`
- `domain`
- `model/data`
- `ui/quiz`
- Added `config/detekt/detekt.yml` to the `ui:quiz` module to configure Detekt rules, including exceptions for Jetpack Compose naming conventions, complexity rules for Composable functions, and style guidelines for magic numbers and unused private members. It also enables trailing commas for call sites and declaration sites.
- **Binary File:**
- Added `App.apk`.
This commit refactors the placement of the background image, moving it from `QuizScreen` to the main `KahootQuizApp` composable. This ensures the background is consistently applied across the app.
Additionally, this commit includes:
- Removal of unused Detekt configuration file (`ui/quiz/config/detekt/detekt.yml`).
- Minor code cleanup:
- Removed commented-out code in `Theme.kt` and `Type.kt`.
- Removed trailing blank lines in various domain model files.
- Added `@file:Suppress("TooManyFunctions")` to `QuizMapper.kt`.
- Added `@file:Suppress("MatchingDeclarationName")` to `QuizNavigation.kt`.
- Used `1.seconds` instead of `1000` (Long) for delay in `QuizScreenViewModel`.
This commit introduces the foundational structure of the Kahoot Quiz application and implements the core network layer.
Key changes include:
- Added new Gradle modules: `core:network`, `domain`, `model:data`, and `ui:quiz`.
- Configured Detekt for static code analysis in the new modules.
- Implemented Retrofit and Gson for network communication and JSON parsing.
- Defined DTOs for the Kahoot quiz API response, splitting them into logical files (QuizResponseDto, CommonDtos, CoverDtos, QuestionDtos, MetadataDtos, ContentTagsDto) for better organization.
- Created `QuizApi` interface with a GET request for fetching quiz data.
- Added `QuizService` interface and its initial implementation `QuizServiceImpl`.
- Set up Hilt for dependency injection in the network module, providing Retrofit and QuizApi instances.
- Included a `sample_quiz.json` file for testing and development.
- Added unit tests (`QuizResponseDtoParsingTest`) to verify the correct parsing of the sample JSON into DTOs.
- Updated `.gitignore` to exclude additional generated files and IDE specific folders.
- Modified `settings.gradle.kts` to include the new modules.
- Updated `app/build.gradle.kts` to include dependencies on the new `ui:quiz` and `model:data` modules and removed unused dependencies.
