Immediate Tasks ``` 1. Check if backend is running Run: cd c:\laragon\www\TA\spk_kontrakan && php artisan serve 2. Update base URL in app_config.dart Check your IP: ipconfig (Windows) Update: static const String baseUrl = 'http://:8000/api'; 3. Test API connection Add this to main.dart: await authService.loadToken(); 4. Start building screens using services ``` ### 2. Example Screen Structure ```dart import 'package:spk_mobile/services/kontrakan_service.dart'; class ExampleScreen extends StatefulWidget { @override State createState() => _ExampleScreenState(); } class _ExampleScreenState extends State { final _service = KontrakanService(); bool _isLoading = true; List _data = []; String? _error; @override void initState() { super.initState(); _loadData(); } void _loadData() async { try { setState(() => _isLoading = true); _data = await _service.getKontrakan(); setState(() => _isLoading = false); } catch (e) { setState(() { _error = 'Error: $e'; _isLoading = false; }); } } @override Widget build(BuildContext context) { if (_isLoading) return CircularProgressIndicator(); if (_error != null) return Text(_error!); if (_data.isEmpty) return Text('No data'); return ListView.builder( itemCount: _data.length, itemBuilder: (context, index) { return ListTile( title: Text(_data[index].nama), subtitle: Text('Rp ${_data[index].hargaBulanan}'), ); }, ); } } ``` ### 3. Test API Integration ```dart // Add to main.dart for testing void testAPIs() async { print('Testing APIs...'); await APITestHelper.runAllTests( testEmail: 'test@example.com', testPassword: 'password123', ); } ``` --- ## 📚 Documentation Files - `API_INTEGRATION_GUIDE.md` - Full API reference - `API_QUICKSTART.md` - Quick examples and patterns - `test/api_test_helper.dart` - Test utility class - `API_STATUS.md` - This file --- ## ⚠️ Important Notes 1. **Always Load Token on Startup** ```dart void main() async { WidgetsFlutterBinding.ensureInitialized(); final authService = AuthService(); await authService.loadToken(); runApp(const MyApp()); } ``` 2. **Update API Base URL** - Check your system IP - Update in `lib/config/app_config.dart` - Different for emulator/simulator/real device 3. **File Uploads** - Payment proof must be image file - Use `image_picker` package for file selection - Ensure file exists before uploading 4. **Authentication** - Token automatically saved after login - Token automatically included in requests - Token automatically cleared on logout 5. **Error Handling** - Always check `result['success']` first - Get error message from `result['message']` - Get validation errors from `result['errors']` --- ## 🔧 Troubleshooting ### "Connection Refused" ``` → Backend not running → Fix: php artisan serve → Check firewall port 8000 ``` ### "Unauthorized 401" ``` → Token invalid/expired → Fix: Login again → Check loadToken() called on startup ``` ### "CORS Error" ``` → Backend already configured CORS → If still happening, check config/cors.php ``` ### "Image Upload Failed" ``` → File path doesn't exist → Use image_picker to select file → Check file permissions ``` --- ## 📞 Support For issues or questions: 1. Check `API_INTEGRATION_GUIDE.md` for detailed docs 2. Check `API_QUICKSTART.md` for examples 3. Test endpoints with `APITestHelper` 4. Verify backend is running 5. Check base URL configuration --- ## ✅ Final Checklist - [ ] Backend API is running on port 8000 - [ ] Base URL updated with correct IP - [ ] All services imported in widgets - [ ] Error handling implemented - [ ] Loading states added - [ ] Empty states handled - [ ] Token loaded on app startup - [ ] Tested all main features - [ ] Ready for production build --- **Status: READY FOR DEVELOPMENT** ✅ All API services are fully integrated and ready to use. Start building your screens!
