📝 What Needs To Be Completed

1. Add NotificationBell to Other Screens

You need to add the notification bell to these screens:

MarketScreen.tsx:

import NotificationBell from '../components/NotificationBell';

// In the return statement, update Header:
<Header
  title={t('market')}
  leftComponent={<NotificationBell />}
  rightComponent={<LanguageSwitcher />}  // if it has one
/>

StatsScreen.tsx:

import NotificationBell from '../components/NotificationBell';

<Header
  title={t('stats')}
  leftComponent={<NotificationBell />}
/>

AboutScreen.tsx:

import NotificationBell from '../components/NotificationBell';

<Header
  title={t('about')}
  leftComponent={<NotificationBell />}
/>

2. Add Image URL Field to Admin Notification Form

File: screens/AdminNotificationScreen.tsx

Find the form section (around line 40-100) and add after message field:

// Add to formData state (line ~40)
const [formData, setFormData] = useState<NotificationFormData>({
  title: '',
  message: '',
  priority: 'medium',
  targetAudience: 'all',
  targetMarket: undefined,
  expiryDays: 7,
  imageUrl: '',  // ADD THIS LINE
});

// Add input field in the form (after message input, around line ~150)
<View style={styles.inputGroup}>
  <Text style={styles.label}>{t('imageUrl')} ({t('optional')})</Text>
  <TextInput
    style={styles.input}
    value={formData.imageUrl}
    onChangeText={(text) => setFormData({ ...formData, imageUrl: text })}
    placeholder={t('imageUrlPlaceholder')}
    placeholderTextColor="#9CA3AF"
    autoCapitalize="none"
    keyboardType="url"
  />
  <Text style={styles.helpText}>
    {t('imageUrlHelp')}
  </Text>
</View>

Add to save function (around line ~80-100):

const notificationData: any = {
  title: formData.title.trim(),
  message: formData.message.trim(),
  priority: formData.priority,
  targetAudience: formData.targetAudience,
  createdBy: user.username,
  createdAt: Timestamp.now(),
  expiresAt,
  isActive: true,
  imageUrl: formData.imageUrl?.trim() || null,  // ADD THIS LINE
};

3. Add Translations

File: locales/en.json Add these lines:

"imageUrl": "Image URL",
"optional": "Optional",
"imageUrlPlaceholder": "https://example.com/image.jpg",
"imageUrlHelp": "Enter a direct image URL (HTTPS recommended)",
"hasImage": "Has Image",
"notificationDetails": "Notification Details",
"close": "Close",
"message": "Message",
"priority": "Priority"

File: locales/kn.json Add these lines:

"imageUrl": "ಚಿತ್ರ URL",
"optional": "ಐಚ್ಛಿಕ",
"imageUrlPlaceholder": "https://example.com/image.jpg",
"imageUrlHelp": "ನೇರ ಚಿತ್ರ URL ನಮೂದಿಸಿ (HTTPS ಶಿಫಾರಸು)",
"hasImage": "ಚಿತ್ರವಿದೆ",
"notificationDetails": "ಅಧಿಸೂಚನೆ ವಿವರಗಳು",
"close": "ಮುಚ್ಚಿ",
"message": "ಸಂದೇಶ",
"priority": "ಆದ್ಯತೆ"

4. Remove Notifications from Bottom Tab (Optional)

Since notification bell is now in header, you can optionally remove the Notifications tab:

File: App.tsx

Comment out or remove:

// Remove this entire Tab.Screen block (around line 305-311)
// <Tab.Screen
//   name="Notifications"
//   component={NotificationsScreen}
//   options={{
//     tabBarLabel: t('notifications'),
//   }}
// />

Also remove from icon logic (around line 253-255):

// Remove these lines:
// } else if (route.name === 'Notifications') {
//   iconName = focused ? 'notifications' : 'notifications-outline';
