## 🚀 Next Steps

### 1. Generate Type Adapters

Run the Hive code generator to create `.g.dart` files:

```bash
cd /Users/ssg/project/worker
dart run build_runner build --delete-conflicting-outputs
```

This will generate adapter files for all models and enums.

### 2. Register Adapters

Create or update Hive initialization file (e.g., `lib/core/database/hive_service.dart`):

```dart
import 'package:hive_ce/hive.dart';
import 'package:hive_flutter/hive_flutter.dart';

// Import all generated adapters
import 'package:worker/core/database/models/enums.dart';
import 'package:worker/features/auth/data/models/user_model.dart';
import 'package:worker/features/auth/data/models/user_session_model.dart';
// ... import all other models

class HiveService {
  static Future<void> init() async {
    await Hive.initFlutter();

    // Register all enum adapters
    Hive.registerAdapter(UserRoleAdapter());
    Hive.registerAdapter(UserStatusAdapter());
    Hive.registerAdapter(LoyaltyTierAdapter());
    Hive.registerAdapter(OrderStatusAdapter());
    Hive.registerAdapter(InvoiceTypeAdapter());
    Hive.registerAdapter(InvoiceStatusAdapter());
    Hive.registerAdapter(PaymentMethodAdapter());
    Hive.registerAdapter(PaymentStatusAdapter());
    Hive.registerAdapter(EntryTypeAdapter());
    Hive.registerAdapter(EntrySourceAdapter());
    Hive.registerAdapter(ComplaintStatusAdapter());
    Hive.registerAdapter(GiftCategoryAdapter());
    Hive.registerAdapter(GiftStatusAdapter());
    Hive.registerAdapter(PointsStatusAdapter());
    Hive.registerAdapter(ProjectTypeAdapter());
    Hive.registerAdapter(SubmissionStatusAdapter());
    Hive.registerAdapter(DesignStatusAdapter());
    Hive.registerAdapter(QuoteStatusAdapter());
    Hive.registerAdapter(RoomTypeAdapter());
    Hive.registerAdapter(ContentTypeAdapter());
    Hive.registerAdapter(ReminderTypeAdapter());

    // Register all model adapters
    Hive.registerAdapter(UserModelAdapter());
    Hive.registerAdapter(UserSessionModelAdapter());
    Hive.registerAdapter(ProductModelAdapter());
    Hive.registerAdapter(StockLevelModelAdapter());
    Hive.registerAdapter(CartModelAdapter());
    Hive.registerAdapter(CartItemModelAdapter());
    Hive.registerAdapter(OrderModelAdapter());
    Hive.registerAdapter(OrderItemModelAdapter());
    Hive.registerAdapter(InvoiceModelAdapter());
    Hive.registerAdapter(PaymentLineModelAdapter());
    Hive.registerAdapter(LoyaltyPointEntryModelAdapter());
    Hive.registerAdapter(GiftCatalogModelAdapter());
    Hive.registerAdapter(RedeemedGiftModelAdapter());
    Hive.registerAdapter(PointsRecordModelAdapter());
    Hive.registerAdapter(ProjectSubmissionModelAdapter());
    Hive.registerAdapter(DesignRequestModelAdapter());
    Hive.registerAdapter(QuoteModelAdapter());
    Hive.registerAdapter(QuoteItemModelAdapter());
    Hive.registerAdapter(ChatRoomModelAdapter());
    Hive.registerAdapter(MessageModelAdapter());
    Hive.registerAdapter(NotificationModelAdapter());
    Hive.registerAdapter(ShowroomModelAdapter());
    Hive.registerAdapter(ShowroomProductModelAdapter());
    Hive.registerAdapter(PaymentReminderModelAdapter());
    Hive.registerAdapter(AuditLogModelAdapter());

    // Open boxes
    await Hive.openBox(HiveBoxNames.userBox);
    await Hive.openBox(HiveBoxNames.productBox);
    await Hive.openBox(HiveBoxNames.cartBox);
    await Hive.openBox(HiveBoxNames.orderBox);
    await Hive.openBox(HiveBoxNames.loyaltyBox);
    await Hive.openBox(HiveBoxNames.projectBox);
    await Hive.openBox(HiveBoxNames.notificationBox);
    // ... open all other boxes
  }
}
```

### 3. Create Datasources

Implement local datasources using these models:

```dart
// Example: lib/features/auth/data/datasources/auth_local_datasource.dart
class AuthLocalDataSource {
  final Box userBox;

  Future<void> cacheUser(UserModel user) async {
    await userBox.put(HiveKeys.currentUser, user);
  }

  UserModel? getCachedUser() {
    return userBox.get(HiveKeys.currentUser) as UserModel?;
  }
}
```

### 4. Update Repository Implementations

Use models in repository implementations for caching:

```dart
class ProductRepositoryImpl implements ProductRepository {
  final ProductRemoteDataSource remoteDataSource;
  final ProductLocalDataSource localDataSource;

  @override
  Future<List<Product>> getProducts() async {
    try {
      // Try to fetch from API
      final products = await remoteDataSource.getProducts();

      // Cache locally
      await localDataSource.cacheProducts(products);

      return products;
    } catch (e) {
      // Return cached data on error
      return localDataSource.getCachedProducts();
    }
  }
}
```

## ⚠️ Important Notes

### Type ID Management
- All Type IDs are unique across the app (0-24 for models, 30-50 for enums)
- Never change a Type ID once assigned - it will break existing cached data
- Type IDs are centrally managed in `/Users/ssg/project/worker/lib/core/constants/storage_constants.dart`

### JSONB Field Handling
- All JSONB fields from database are stored as JSON-encoded strings in Hive
- Helper methods provide easy access to parsed data (e.g., `companyInfoMap`, `participantsList`)
- Always use try-catch when decoding JSON fields

### DateTime Support
- Hive CE natively supports DateTime
- No need for custom serialization
- Use `DateTime.parse()` for JSON and `toIso8601String()` for API

### Best Practices
- Always extend `HiveObject` for automatic key management
- Use sequential field numbering (0, 1, 2, ...)
- Include comprehensive documentation
- Implement helper methods for computed properties
- Handle null values appropriately
