Enhance serialization #41
Conversation
- Implement static toJson method in LocalAd abstract class - Add type-based dispatching for serialization to concrete ad types - Include error handling for unknown ad types - Enable serialization of LocalAd instances to JSON format
- Implement a static factory method to serialize FeedItem instances to JSON - Add type-based dispatching to the correct toJson method for each subclass - Handle serialization for all known FeedItem types, including ContentCollectionItem with generic types - Include error handling for unknown types
…alization tests - Fix typo in exception message: 'LocalAds' -> 'LocalAd' - Add unit tests for toJson method dispatching in LocalAd class - Verify serialization for all LocalAd subclasses: LocalNativeAd, LocalBannerAd, LocalInterstitialAd, and LocalVideoAd
- Update code coverage badge in README.md from 99% to 98%

Summary of Changes
Hello @fulleni, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly enhances the serialization capabilities within the application's core models. By introducing static factory methods for FeedItem and LocalAd, it streamlines the process of converting complex, polymorphic data structures into their corresponding JSON representations. This change improves the robustness and maintainability of the serialization logic, making it easier to handle various concrete implementations of abstract base types.
Highlights
- Polymorphic Serialization: Introduced static toJson factory methods on FeedItem and LocalAd base classes to enable type-safe serialization of their concrete subtypes into JSON maps.
- FeedItem Serialization: The new FeedItem.toJson method dispatches serialization based on the type field, supporting Headline, Topic, Source, Country, CallToAction, LocalAd, and ContentCollection items.
- LocalAd Serialization: The new LocalAd.toJson method dispatches serialization based on the adType field, supporting LocalNativeAd, LocalBannerAd, LocalInterstitialAd, and LocalVideoAd types.
- Test Coverage: Added new unit tests to verify the correct dispatching and serialization behavior of the LocalAd.toJson method for all its supported ad types.

Code Review
This pull request introduces centralized toJson serialization logic for FeedItem and LocalAd, which is a good architectural improvement. My review focuses on improving the maintainability of the new dispatcher methods and highlights the need for comprehensive testing. Specifically, the serialization for ContentCollectionItem can be made more robust, and the new FeedItem.toJson method is missing unit tests, which has led to a drop in code coverage.
