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