Complete App Restructure - Role-Based UI + Map Satellite View

Date: October 19, 2025

Overview

Complete restructuring of NDMA Training App with proper role-based navigation, separate UIs for each role, and satellite map view feature.

Changes Implemented

1. Trainee-Specific Screens Created

TraineeHomeScreen.js ✅

Purpose: Dedicated home screen for trainee users (NOT a copy of trainer home)

Features:

  • Welcome header with trainee name + role badge
  • Stats Cards (3 cards):
    • Attended trainings (blue)
    • Missed trainings (red)
    • Upcoming trainings (green)
  • Quick Actions Grid (4 buttons):
    • View Schedule (calendar icon)
    • My Attendance (checkmark icon)
    • Certificates (document icon)
    • Help (help-circle icon)
  • Upcoming Trainings List:
    • Shows trainee's registered trainings
    • Empty state: "No upcoming trainings - Check the map"
  • Backend Integration Ready:
    • MongoDBService.getUpcomingTrainings()
    • MongoDBService.getMyAttendance(userId)
  • Animations: react-native-animatable (fadeIn, fadeInUp, fadeInDown)
  • Pull to Refresh: RefreshControl

NO ACCESS TO:

  • ❌ Add Training button
  • ❌ Reports screen
  • ❌ Explore screen
  • ❌ Authority approvals

TraineeMapScreen.js ✅

Purpose: Map view showing nearby active training sessions

Features:

  • Header: "Nearby Trainings" title
  • Map Type Toggle: Standard / Satellite / Hybrid (same as trainer/authority)
  • User Location Marker: Blue circle with person icon
  • Training Markers: Green circles with school icon (active sessions)
  • My Location Button: Center map on user's GPS location
  • Info Card: Shows "No active trainings nearby" when empty
  • GPS Permission: Requests location permission on load
  • Backend Integration Ready:
    • MongoDBService.getActiveTrainings() - fetch trainings within radius

Map Features:

  • PROVIDER_GOOGLE - Google Maps SDK
  • showsUserLocation - shows blue dot
  • showsCompass - compass control
  • Animated marker transitions

NO ACCESS TO:

  • ❌ Mark location as live
  • ❌ Add training form
  • ❌ Training reports

2. Map Satellite View Added

MapScreen.js Updates ✅

For: Trainer + Authority

New State:

const [mapType, setMapType] = useState('standard'); 
// Options: 'standard' | 'satellite' | 'hybrid'

Map Type Toggle Button:

  • Location: Top-right corner of map (floating button)
  • Icon: layers-outline (Ionicons)
  • Label: Shows current map type
  • Cycling: Standard → Satellite → Hybrid → Standard
  • Style: White background, rounded, shadow, z-index 10

MapView Props Added:

<MapView 
  mapType={mapType}  // NEW
  // ... other props
/>

Button Styles:

mapTypeButton: {
  position: 'absolute',
  top: 16,
  right: 16,
  flexDirection: 'row',
  alignItems: 'center',
  gap: 6,
  backgroundColor: '#FFFFFF',
  paddingHorizontal: 14,
  paddingVertical: 10,
  borderRadius: 24,
  shadowColor: '#000',
  shadowOffset: { width: 0, height: 2 },
  shadowOpacity: 0.15,
  shadowRadius: 6,
  elevation: 4,
  zIndex: 10,
}

Now Works: Map shows satellite imagery when toggle clicked!

3. Role-Based Navigation (App.js)

Updated MainTabs Component ✅

3 Navigation Structures:

Authority (4 tabs):

  1. 🏠 Home → AuthorityHomeScreen
  2. 🗺️ Map → MapScreen (with satellite toggle)
  3. 📄 Approvals → AuthorityReportsScreen
  4. 👤 Profile → ProfileScreen

Trainee (3 tabs):

  1. 🏠 Home → TraineeHomeScreen ← NEW
  2. 🗺️ Map → TraineeMapScreen ← NEW
  3. 👤 Profile → ProfileScreen

Trainer (6 tabs):

  1. 🏠 Home → HomeScreen
  2. ➕ Add → AddTrainingScreen
  3. 🗺️ Map → MapScreen (with satellite toggle)
  4. 📄 Reports → ReportsScreen
  5. 🧭 Explore → ExploreScreen
  6. 👤 Profile → ProfileScreen

Logic:

{user?.role === 'authority' ? (
  // Authority tabs
) : user?.role === 'trainee' ? (
  // Trainee tabs (NEW)
) : (
  // Trainer tabs (default)
)}

Imports Added:

import TraineeHomeScreen from './src/screens/TraineeHomeScreen';
import TraineeMapScreen from './src/screens/TraineeMapScreen';
