- Add exports for local_banner_ad, local_interstitial_ad, local_native_ad, and local_video_ad
- Create new file with predefined local ad fixtures for testing and development purposes - Include various types of local ads: native, banner, interstitial, and video - Each ad has placeholder IDs and sample content with example URLs
- Convert LocalAd into an abstract class acting as a router for different local ad types - Implement factory constructor to dispatch JSON deserialization to concrete types - Remove properties and methods specific to native ads, as they will be handled by subclass - Add documentation explaining the new routing mechanism for local ad types
- Change parent class from FeedItem to LocalAd - Add @OverRide for toJson method - Include adType and type in JSON representation - Update constructor to use AdType.banner
…lization - Change parent class from FeedItem to LocalAd - Update constructor to use AdType.interstitial - Override toJson method to include adType and type for routing and compatibility
- Change LocalNativeAd to extend LocalAd - Update constructor and toJson method - Add adType field and include it in JSON representation - Maintain type field for backwards compatibility
- Change LocalVideoAd to extend LocalAd instead of FeedItem - Update constructor to use adType parameter - Modify toJson method to include both adType and type - Update props to include adType - Adjust copyWith method for new parameter
…ndling - Remove json_annotation and related code - Replace AdType enum with String directly - Simplify.fromJson factory method - Remove toJson method declaration
- Remove unnecessary overrides and props - Simplify adType assignment in constructor
…oJson - Change adType from AdType enum to string - Remove override of toJson method - Simplify props list in get props override
- Change adType from AdType enum to string literal 'native' - Remove @OverRide annotation for toJson method - Simplify toJson implementation by removing redundant comments
…verride - Remove @OverRide annotation for toJson and props - Directly assign 'video' string to super adType - Simplify toJson method by removing unnecessary comments - Remove unnecessary List<Object?> get props override
- Update local ads fixtures to use IDs from fixture_ids.dart - Remove unnecessary imports
- Replace hardcoded LocalAd with fixture data - Update test descriptions to reflect use of LocalNativeAd - Adjust type checks in tests to use LocalNativeAd instead of LocalAd
…and concrete subclasses - Refactor tests to cover LocalAd as an abstract class with named constructors - Add tests for fromJson dispatching to correct subclasses - Include tests for props and equality checks on a concrete subclass (LocalNativeAd) - Update test descriptions and expectations to reflect the new implementation

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 implements a significant architectural improvement to the local ad system by transitioning from a single, monolithic LocalAd class to a more robust and extensible abstract base class with distinct concrete ad type implementations. This refactoring enhances the system's ability to manage diverse ad formats, simplifies future additions of new ad types, and improves overall code organization and clarity.
Highlights
- Refactored LocalAd Model: The
LocalAdclass has been refactored from a concrete class into an abstract base class. This introduces a polymorphic structure for handling different types of local advertisements. - Introduced Specific Ad Subtypes: New concrete ad types have been added:
LocalNativeAd,LocalBannerAd,LocalInterstitialAd, andLocalVideoAd. Each subtype now encapsulates properties specific to its ad format, inheriting common functionality from the abstractLocalAd. - Centralized JSON Deserialization: The
LocalAd.fromJsonfactory constructor now acts as a central dispatcher, intelligently deserializing JSON data into the correct concrete ad subtype based on theadTypefield, improving flexibility and maintainability. - Updated Fixtures and Tests: Fixture data for local ads has been updated to reflect the new subtype structure, and corresponding tests have been significantly refactored to validate the new class hierarchy and JSON serialization/deserialization logic.

Code Review
This pull request is a great refactoring that introduces specific subtypes for LocalAd (LocalNativeAd, LocalBannerAd, etc.), moving from a single generic class to a more robust and type-safe hierarchy with an abstract base class. The use of a factory constructor in the LocalAd base class for deserialization is a clean and effective pattern. The changes are well-implemented and the tests have been updated to cover the new structure.
I have a couple of minor suggestions to improve consistency and fix a typo. Overall, this is a high-quality contribution that improves the codebase's maintainability.
- Prefix local ad id constants with 'k' to follow consistent naming convention - Update constant names for local ad ids to improve clarity and consistency
- Replaced hardcoded local ad IDs with predefined constants - Updated all LocalAd instances to use constant IDs - This change improves code maintainability and readability
- Remove local ad exports from feed_decorators.dart - Create new local_ads.dart file for local ad exports - Move local ad model classes to a new local_ads directory - Update models.dart to export new local_ads.dart file
- Correct the typo in the exception message from 'LocalAds' to 'LocalAd' - Improve consistency and accuracy of error reporting
