# City and Ward API Implementation - Complete Guide

## Files Created ✅

1. ✅ `lib/features/account/domain/entities/city.dart`
2. ✅ `lib/features/account/domain/entities/ward.dart`
3. ✅ `lib/features/account/data/models/city_model.dart`
4. ✅ `lib/features/account/data/models/ward_model.dart`
5. ✅ Updated `lib/core/constants/storage_constants.dart`
   - Added `cityBox` and `wardBox`
   - Added `cityModel = 31` and `wardModel = 32`
   - Shifted all enum IDs by +2

## Implementation Status

### Completed:
- ✅ Domain entities (City, Ward)
- ✅ Hive models with type adapters
- ✅ Storage constants updated
- ✅ Build runner generated .g.dart files

### Remaining (Need to implement):

1. **Remote Datasource** - `lib/features/account/data/datasources/location_remote_datasource.dart`
2. **Local Datasource** - `lib/features/account/data/datasources/location_local_datasource.dart`
3. **Repository Interface** - `lib/features/account/domain/repositories/location_repository.dart`
4. **Repository Implementation** - `lib/features/account/data/repositories/location_repository_impl.dart`
5. **Providers** - `lib/features/account/presentation/providers/location_provider.dart`
6. **Update AddressFormPage** to use the providers

## API Endpoints (from docs/auth.sh)

### Get Cities:
```bash
POST /api/method/frappe.client.get_list
Body: {
  "doctype": "City",
  "fields": ["city_name","name","code"],
  "limit_page_length": 0
}
```

### Get Wards (filtered by city):
```bash
POST /api/method/frappe.client.get_list
Body: {
  "doctype": "Ward",
  "fields": ["ward_name","name","code"],
  "filters": {"city": "96"},
  "limit_page_length": 0
}
```

## Offline-First Strategy

1. **Cities**: Cache in Hive, refresh from API periodically
2. **Wards**: Load from API when city selected, cache per city
