💡 Implementation Tips

1. Start with Modal Component

// components/ui/Modal.tsx
import { Modal, View, Text, Pressable } from 'react-native';

export interface ModalProps {
  visible: boolean;
  title: string;
  onClose: () => void;
  children: React.ReactNode;
}

export const AppModal: React.FC<ModalProps> = ({
  visible,
  title,
  onClose,
  children,
}) => (
  <Modal visible={visible} transparent animationType="slide">
    <Pressable onPress={onClose} style={{ flex: 1 }} />
    {/* Modal content */}
  </Modal>
);

2. Add Toast Notifications

// Create simple toast context for feedback
const [toast, setToast] = useState<{ message: string; type: 'success' | 'error' }|null>(null);

// Show toast when operations complete
useEffect(() => {
  if (operationSuccess) {
    setToast({ message: 'Success!', type: 'success' });
    setTimeout(() => setToast(null), 3000);
  }
}, [operationSuccess]);

3. Implement OTP Input

// components/auth/OTPInput.tsx
// Use separate inputs for each digit
// Auto-focus next input when digit entered
// Clear previous on backspace

4. Maps Routing

// Use Google Maps API or OpenStreetMap routing
// Polyline on map: use MapView.Polyline component
// Request route between pickup → destination
// Update as driver moves

5. Real-time Updates

// Use polling for MVP (check every 5 seconds)
// Replace with WebSocket later for production
setInterval(async () => {
  const location = await apiService.getLiveLocation(rideId);
  // Update map marker
}, 5000);

📱 Device Testing

Android

npm run android
# Or: Expo Go app + scan QR code

iOS

npm run ios
# Or: Expo Go app on device + scan QR code

Testing different screen sizes

• Emulator: Pixel 4a (5.8"), Pixel 6 Pro (6.7")
• Device: Test on 4.5", 5.5", 6.5" phones

---

🐛 Troubleshooting

Location Permission Denied

// Check app permissions in device settings
// Android: Settings → Apps → ChartKeke → Permissions
// iOS: Settings → Charter Keke → Location

Map Not Showing

// Ensure MapView imported: import MapView from 'react-native-maps'
// Check initialRegion has valid lat/lon
// Use default: Debari, Lagos (6.5244, 3.3792)

API Requests Failing

// Check .env.local has correct API_URL
// Ensure backend is running and reachable
// Check network: toggleOffline in dev tools

Offline Sync Not Working

// Enable airplane mode to test offline
// Check cacheService.getSyncQueue() has items
// Manually call: syncService.sync()

---

📚 Next Steps

1. Pick a screen from the implementation checklist
2. Copy template structure from existing screen (e.g., home.tsx)
3. Add your components (use UI component library)
4. Test with live data from API
5. Submit for review
