// KISS Firebase Repository Example App
//
// This example app demonstrates the full capabilities of the kiss_firebase_repository
// package in a real Flutter application. It showcases:
//
// 1. RepositoryFirestore setup with type-safe conversions
// 2. Auto-generated Firestore IDs using createWithAutoId()
// 3. Real-time streaming with streamQuery()
// 4. Full CRUD operations (Create, Read, Update, Delete)
// 5. Error handling and user feedback
// 6. Firebase emulator integration for development
// 7. Custom Query system with QueryBuilder and search functionality
//
// The app is fully integrated with integration tests in ../integration_test/app_test.dart
// which verify that all repository operations work correctly with a real Firebase instance.
//
// To run the app with Firebase emulator:
//   cd example && ./scripts/run_with_emulator.sh
//
// To run integration tests:
//   cd example && ./scripts/run_integration_tests.sh
