LoginScreen Fixes - October 19, 2025

Issues Fixed

1. Picker Import Missing

Error: Property 'Picker' doesn't exist

Fix: Added proper import for Picker component

import { Picker } from '@react-native-picker/picker';

2. Trainee Password Field Missing

Problem: Trainee registration didn't collect password, so backend couldn't authenticate trainee later

Fix: Added password field to trainee registration form

• Password field added between "State" and consent checkboxes
• Password validation added to registration logic
• Backend now receives password during trainee registration

Updated Registration Logic:

const traineeData = {
  name,
  phone,
  password, // Now included
  role: 'trainee',
  age_bracket: ageBracket,
  district,
  state,
  consent_location: consentLocation,
  consent_attendance: consentAttendance,
};

Registration Flow Now:

1. Trainee enters: Name, Phone, Age, District, State, Password
2. Checks both consent boxes
3. Taps "Create account"
4. Backend creates account with phone + password
5. Auto-login after registration (no need to re-enter credentials)

3. Emojis Replaced with Icon Libraries

Problem: Emojis look AI-generated and unprofessional

Fix: Replaced all emojis with proper icon libraries from Expo

Header Icon

Before: 🏛️ (emoji) After:

<View style={styles.iconContainer}>
  <MaterialIcons name="security" size={48} color="#2C5282" />
</View>

Tab Icons

Before:

• 👨‍🏫 Trainer
• 👤 Trainee
• 🏛️ Authority

After:

// Trainer Tab
<FontAwesome5 name="chalkboard-teacher" size={16} color={...} />
<Text>Trainer</Text>

// Trainee Tab
<Ionicons name="person" size={18} color={...} />
<Text>Trainee</Text>

// Authority Tab
<MaterialIcons name="verified-user" size={18} color={...} />
<Text>Authority</Text>

Consent Checkboxes

Before: ✓ (text checkmark) After:

<Ionicons name="checkmark" size={16} color="#FFFFFF" />

New Styles Added

Icon Container

iconContainer: {
  width: 80,
  height: 80,
  borderRadius: 40,
  backgroundColor: '#EBF4FF',
  alignItems: 'center',
  justifyContent: 'center',
  marginBottom: 8,
}

Tab with Icon + Text

tab: {
  flex: 1,
  paddingVertical: 10,
  borderRadius: 16,
  alignItems: 'center',
  justifyContent: 'center',
  flexDirection: 'row', // Icon + text horizontal
  gap: 6,
}

Icon Libraries Used

Imported from @expo/vector-icons:

1. Ionicons - Person icon, checkmark icon
2. MaterialIcons - Security icon (header), verified-user icon (authority tab)
3. FontAwesome5 - Chalkboard-teacher icon (trainer tab)

All these icons are already included with Expo, no additional packages needed.

Updated Validation

Trainee Registration Validation:

// Name, phone, password required
if (!name || !phone || !password) {
  Alert.alert('Error', 'Please enter name, phone number, and password');
  return;
}

// Phone exactly 10 digits
if (phone.length !== 10) {
  Alert.alert('Error', 'Phone number must be exactly 10 digits');
  return;
}

// Both consents required
if (!consentLocation || !consentAttendance) {
  Alert.alert('Consent Required', 'Please accept both consent agreements to register');
  return;
}

Backend Integration Updated

POST /api/auth/register (Trainee)

Before:

{
  "role": "trainee",
  "name": "Rajesh Kumar",
  "phone": "9876543210",
  // No password - backend used phone as password
}

After:

{
  "role": "trainee",
  "name": "Rajesh Kumar",
  "phone": "9876543210",
  "password": "user_chosen_password", // Now included
  "age_bracket": "26-35",
  "district": "Mumbai",
  "state": "Maharashtra",
  "consent_location": true,
  "consent_attendance": true
}

Trainee Registration Form (Final)

1. Full Name (text input)
2. Phone Number (10-digit, phone-pad keyboard)
3. Age Bracket (picker: 18-25, 26-35, 36-45, 46-60, 60+)
4. District (text input)
5. State (text input)
6. Password (secure entry) ← NEW
7. Consent: Location sharing (checkbox with icon)
8. Consent: Attendance tracking (checkbox with icon)
