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 refactors how country data is handled within the application for headlines and sources. The primary goal is to streamline the process by moving away from a repository-based approach for country entities and instead integrating a dedicated country_picker package. This change simplifies data flow, reduces boilerplate, and provides a more robust and user-friendly country selection experience.

Highlights

• Country Data Management Streamlined: The application's handling of country data has been refactored. The DataRepository<Country> and its associated data clients have been removed from the application's core (lib/app/view/app.dart, lib/bootstrap.dart), indicating a shift from fetching country data from a backend to client-side management.
• Integration of country_picker Package: The country_picker package (pubspec.yaml, pubspec.lock) has been introduced to provide a rich and standardized UI for country selection, replacing previous custom dropdown implementations.
• New CountryPickerFormField Widget: A reusable CountryPickerFormField widget (lib/shared/widgets/country_picker_form_field.dart) has been added. This widget abstracts the country_picker integration, improving UI consistency and maintainability across the application's forms.
• Data Model Adaptation Utilities: New utility functions (adaptPackageCountryToCoreCountry, adaptCoreCountryToPackageCountry) have been introduced in lib/shared/utils/country_adapter.dart. These functions seamlessly convert between the country_picker's Country object and the application's internal core.Country model, ensuring data compatibility.
• BLoC Layer Updates: All relevant BLoCs (CreateHeadlineBloc, CreateSourceBloc, EditHeadlineBloc, EditSourceBloc) have been updated to remove Country repository dependencies, adjust state management (no longer storing a list of all countries), and utilize the new country adaptation utilities for handling country selection events.
• UI Form Field Replacement: Existing DropdownButtonFormField widgets used for country selection in headline and source creation/editing pages (lib/content_management/view/create_headline_page.dart, lib/content_management/view/create_source_page.dart, lib/content_management/view/edit_headline_page.dart, lib/content_management/view/edit_source_page.dart) have been replaced with the new CountryPickerFormField.

Code Review

This pull request refactors the way country data is handled by removing the CountryRepository and integrating the country_picker package. The changes are consistently applied across the relevant BLoCs and UI components. I've provided a few suggestions to enhance the new shared widget with localization and to fix minor inconsistencies in BLoC event handlers. Overall, this is a solid refactoring.
