New Feature

Create a new feature following the project's Clean Architecture and conventions.

Steps

1. Domain layer — define entities, use cases in lib/domain/, and repository interfaces in lib/domain/repositories/
2. Data layer — implement the repository in lib/data/
3. Register dependencies — add new services and use cases to lib/di/service_locator.dart
4. Presentation layer — create a feature folder in lib/ui/features/<feature_name>/ with:
   • A Cubit and its State class (using Equatable)
   • Page and widget files (one widget class per file — no _build* methods)
5. Tests — add tests that mirror the lib/ structure:
   • Unit tests for use cases in test/unit/domain/
   • Unit tests for the cubit in test/unit/features/<feature_name>/
   • Widget tests in test/widget/features/<feature_name>/
6. Validate — run flutter analyze and flutter test before finishing

Conventions Checklist

• UI texts are in German
• Code comments, methods, and variables are in English
• Each class has its own file
• Cubit is used instead of Bloc
• All state fields are in the Equatable props list
• Shared widgets go into lib/ui/shared/widgets/
• Tests follow Given-When-Then (Gherkin) structure
