+# Auto-Login Debug Guide
+
+**Date**: October 10, 2025
+
+---
+
+## Testing Auto-Login
+
+### Test Scenario
+
+1. **Login with Remember Me CHECKED**
+2. **Close app completely** (swipe from recent apps)
+3. **Reopen app**
+4. **Expected**: Should auto-login and go to MainScreen
+
+---
+
+## Debug Logs to Watch
+
+When you reopen the app, you should see these logs:
+
+### Step 1: App Starts
+```
+🚀 Initializing auth state...
+```
+
+### Step 2: Check for Saved Token
+```
+🔍 Checking authentication...
+🔍 Has token in storage: true/false
+```
+
+### If Token Found (Remember Me was checked):
+```
+🔍 Has token in storage: true
+🔍 Token retrieved, length: 200+
+✅ Token loaded from storage and set in DioClient
+🚀 isAuthenticated result: true
+🚀 Token found, fetching user profile...
+📡 DataSource: Calling profile API...
+✅ Profile loaded: Admin User
+✅ Initialize complete: isAuthenticated=true
+AuthWrapper build: isAuthenticated=true, isLoading=false
+```
+**Result**: ✅ Auto-login success → Shows MainScreen
+
+### If No Token (Remember Me was NOT checked):
+```
+🔍 Has token in storage: false
+❌ No token found in storage
+🚀 isAuthenticated result: false
+❌ No token found, user needs to login
+AuthWrapper build: isAuthenticated=false, isLoading=false
+```
+**Result**: ✅ Shows LoginPage (expected behavior)
+
+---
+
+## How to Test
+
+### Test 1: Remember Me ON → Auto-Login
+```bash
+1. flutter run
+2. Login with Remember Me CHECKED ✅
+3. Verify you see:
+   🔐 Repository: Token saved to secure storage (persistent)
+4. Hot restart (press 'R' in terminal)
+5. Should see auto-login logs
+6. Should go directly to MainScreen
+```
+
+### Test 2: Remember Me OFF → Must Login Again
+```bash
+1. Logout from Settings
+2. Login with Remember Me UNCHECKED ❌
+3. Verify you see:
+   🔐 Repository: Token NOT saved (session only)
+4. Hot restart (press 'R' in terminal)
+5. Should see:
+   🔍 Has token in storage: false
+6. Should show LoginPage
+```
+
+### Test 3: Full App Restart
+```bash
+1. Login with Remember Me CHECKED
+2. Close app completely (swipe from recent apps)
+3. Reopen app
+4. Should auto-login
+```
+
+---
+
+## Common Issues
+
+### Issue 1: "Has token in storage: false" even after login with Remember Me
+
+**Possible causes**:
+- Backend returned error during login
+- Remember Me checkbox wasn't actually checked
+- Hot reload instead of hot restart (use 'R' not 'r')
+
+**Fix**:
+- Check login logs show: `Token saved to secure storage (persistent)`
+- Use hot restart ('R') not hot reload ('r')
+
+### Issue 2: Token found but profile fails
+
+**Logs**:
+```
+🔍 Has token in storage: true
+✅ Token loaded from storage
+🚀 Token found, fetching user profile...
+❌ Failed to get profile: [error message]
+```
+
+**Possible causes**:
+- Token expired
+- Backend not running
+- Network error
+
+**Fix**:
+- Check backend is running
+- Token might have expired (login again)
+
+### Issue 3: Initialize never called
+
+**Symptom**: No `🚀 Initializing auth state...` log on app start
+
+**Cause**: `initialize()` not called in app.dart
+
+**Fix**: Verify `app.dart` has:
+```dart
+@override
+void initState() {
+  super.initState();
+  WidgetsBinding.instance.addPostFrameCallback((_) {
+    ref.read(authProvider.notifier).initialize();
+  });
+}
+```
+
+---
+
+## Expected Log Flow
+
+### On First App Start (No Token)
+```
+🚀 Initializing auth state...
+🔍 Checking authentication...
+🔍 Has token in storage: false
+❌ No token found in storage
+🚀 isAuthenticated result: false
+❌ No token found, user needs to login
+AuthWrapper build: isAuthenticated=false, isLoading=false
+→ Shows LoginPage
+```
+
+### After Login (Remember Me = true)
+```
+REQUEST[POST] => PATH: /auth/login
+📡 DataSource: Calling login API...
+🔐 Repository: Starting login (rememberMe: true)...
+🔐 Repository: Token saved to secure storage (persistent)
+✅ Login SUCCESS
+✅ State updated: isAuthenticated=true
+AuthWrapper build: isAuthenticated=true, isLoading=false
+→ Shows MainScreen
+```
+
+### On App Restart (Token Saved)
+```
+🚀 Initializing auth state...
+🔍 Checking authentication...
+🔍 Has token in storage: true
+🔍 Token retrieved, length: 247
+✅ Token loaded from storage and set in DioClient
+🚀 isAuthenticated result: true
+🚀 Token found, fetching user profile...
+REQUEST[GET] => PATH: /auth/profile
+📡 DataSource: Response...
+✅ Profile loaded: Admin User
+✅ Initialize complete: isAuthenticated=true
+AuthWrapper build: isAuthenticated=true, isLoading=false
+→ Shows MainScreen (AUTO-LOGIN SUCCESS!)
+```
+
+---
+
+## Quick Test Commands
+
+```bash
+# Test 1: Login with Remember Me
+flutter run
+# Login with checkbox checked
+# Press 'R' to hot restart
+# Should auto-login
+
+# Test 2: Login without Remember Me
+# Logout first
+# Login with checkbox unchecked
+# Press 'R' to hot restart
+# Should show login page
+```
+
+---
+
+## Summary
+
+The auto-login feature works by:
+
+1. **On Login**: If Remember Me = true → Save token to SecureStorage
+2. **On App Start**: Check SecureStorage for token
+3. **If Token Found**: Load it, set in DioClient, fetch profile → Auto-login
+4. **If No Token**: Show LoginPage
+

+# Auto-Login Issue Fixed!
+
+**Date**: October 10, 2025
+**Status**: ✅ **FIXED**
+
+---
+
+## The Problem
+
+Auto-login was failing with:
+```
+❌ Failed to get profile: type 'Null' is not a subtype of type 'String' in type cast
+```
+
+### Root Cause
+
+The `/auth/profile` endpoint returns a user object **WITHOUT** the `createdAt` field:
+
+```json
+{
+  "id": "b938f48f-4032-4144-9ce8-961f7340fa4f",
+  "email": "admin@retailpos.com",
+  "name": "Admin User",
+  "roles": ["admin"],
+  "isActive": true
+  // ❌ Missing: createdAt, updatedAt
+}
+```
+
+But `UserModel.fromJson()` was expecting `createdAt` to always be present:
+
+```dart
+// BEFORE (causing crash)
+final createdAt = DateTime.parse(json['createdAt'] as String);
+// ❌ Crashes when createdAt is null
+```
+
+---
+
+## The Fix
+
+Updated `UserModel.fromJson()` to handle missing `createdAt` and `updatedAt` fields:
+
+**File**: `lib/features/auth/data/models/user_model.dart`
+
+```dart
+factory UserModel.fromJson(Map<String, dynamic> json) {
+  // ✅ createdAt is now optional, defaults to now
+  final createdAt = json['createdAt'] != null
+      ? DateTime.parse(json['createdAt'] as String)
+      : DateTime.now();
+
+  return UserModel(
+    id: json['id'] as String,
+    name: json['name'] as String,
+    email: json['email'] as String,
+    roles: (json['roles'] as List<dynamic>).cast<String>(),
+    isActive: json['isActive'] as bool? ?? true,
+    createdAt: createdAt,
+    // ✅ updatedAt is also optional, defaults to createdAt
+    updatedAt: json['updatedAt'] != null
+        ? DateTime.parse(json['updatedAt'] as String)
+        : createdAt,
+  );
+}
+```
+
+---
+
+## How Auto-Login Works Now
+
+### Step 1: Login with Remember Me ✅
+```
+User logs in with Remember Me checked
+  ↓
+Token saved to SecureStorage
+  ↓
+Token set in DioClient
+  ↓
+User navigates to MainScreen
+```
+
+### Step 2: App Restart
+```
+App starts
+  ↓
+initialize() called
+  ↓
+Check SecureStorage for token
+  ↓
+Token found!
+  ↓
+Load token and set in DioClient
+  ↓
+Fetch user profile with GET /auth/profile
+  ↓
+Parse profile (now handles missing createdAt)
+  ↓
+✅ Auto-login success!
+  ↓
+Navigate to MainScreen (no login page)
+```
+
+---
+
+## Expected Logs on Restart
+
+```
+📱 RetailApp: initState called
+📱 RetailApp: Calling initialize()...
+🚀 Initializing auth state...
+🔍 Checking authentication...
+💾 SecureStorage: Token read result - exists: true, length: 252
+✅ Token loaded from storage and set in DioClient
+🚀 isAuthenticated result: true
+🚀 Token found, fetching user profile...
+📡 DataSource: Calling getProfile API...
+REQUEST[GET] => PATH: /auth/profile
+RESPONSE[200] => PATH: /auth/profile
+📡 DataSource: User parsed successfully: Admin User
+✅ Profile loaded: Admin User
+✅ Initialize complete: isAuthenticated=true
+AuthWrapper build: isAuthenticated=true, isLoading=false
+→ Shows MainScreen ✅
+```
+
+---
+
+## Testing Auto-Login
+
+### Test 1: With Remember Me
+```bash
+1. flutter run
+2. Login with Remember Me CHECKED ✅
+3. See: "Token saved to secure storage (persistent)"
+4. Press 'R' to hot restart
+5. Expected: Auto-login to MainScreen (no login page)
+```
+
+### Test 2: Without Remember Me
+```bash
+1. Logout from Settings
+2. Login with Remember Me UNCHECKED ❌
+3. See: "Token NOT saved (session only)"
+4. Press 'R' to hot restart
+5. Expected: Shows LoginPage (must login again)
+```
+
+---
+
+## API Response Differences
+
+### Login Response
+```json
+{
+  "success": true,
+  "data": {
+    "access_token": "...",
+    "user": {
+      "id": "...",
+      "email": "...",
+      "name": "...",
+      "roles": ["admin"],
+      "isActive": true,
+      "createdAt": "2025-10-10T02:27:42.523Z"  // ✅ Has createdAt
+    }
+  },
+  "message": "Operation successful"
+}
+```
+
+### Profile Response
+```json
+{
+  "success": true,
+  "data": {
+    "id": "...",
+    "email": "...",
+    "name": "...",
+    "roles": ["admin"],
+    "isActive": true
+    // ❌ Missing: createdAt, updatedAt
+  }
+}
+```
+
+**Solution**: UserModel now handles both cases gracefully.
+
+---
+
+## Files Modified
+
+✅ `lib/features/auth/data/models/user_model.dart`
+- Made `createdAt` optional in `fromJson()`
+- Defaults to `DateTime.now()` if missing
+- Made `updatedAt` optional, defaults to `createdAt`
+
+✅ `lib/features/auth/data/datasources/auth_remote_datasource.dart`
+- Added debug logging for profile response
+- Already correctly extracts nested `data` object
+
+---
+
+## Summary
+
+🎉 **Auto-login is now fully working!**
+
+The issue was that your backend's `/auth/profile` endpoint returns a minimal user object without timestamp fields, while the `/auth/login` endpoint includes them. The UserModel now gracefully handles both response formats.
+
+### What Works Now:
+✅ Login with Remember Me → Token saved
+✅ App restart → Token loaded → Profile fetched → Auto-login
+✅ Login without Remember Me → Token not saved → Must login again
+✅ Logout → Token cleared → Back to login page
+
+---
+
+## Test It Now!
+
+```bash
+# Start the app
+flutter run
+
+# Login with Remember Me checked
+# Close and reopen, or press 'R'
+# Should auto-login to MainScreen!
+```
+
+🚀 **Auto-login is complete and working!**

REMEMBER_ME_FEATURE.md

+# Remember Me Feature
+
+**Date**: October 10, 2025
+**Status**: ✅ **IMPLEMENTED**
+
+---
+
+## Overview
+
+The "Remember Me" feature allows users to stay logged in across app restarts. When enabled, the authentication token is saved to persistent secure storage. When disabled, the token is only kept in memory for the current session.
+
+---
+
+## How It Works
+
+### When Remember Me is CHECKED (✅)
+```
+User logs in with Remember Me enabled
+  ↓
+Token saved to SecureStorage (persistent)
+  ↓
+Token set in DioClient (current session)
+  ↓
+App closes
+  ↓
+App reopens
+  ↓
+Token loaded from SecureStorage
+  ↓
+User auto-logged in ✅
+```
+
+### When Remember Me is UNCHECKED (❌)
+```
+User logs in with Remember Me disabled
+  ↓
+Token NOT saved to SecureStorage
+  ↓
+Token set in DioClient (current session only)
+  ↓
+App closes
+  ↓
+App reopens
+  ↓
+No token in SecureStorage
+  ↓
+User sees login page ✅
+```
+
+---
+
+## Implementation Details
+
+### 1. Login Page UI
+
+**File**: `lib/features/auth/presentation/pages/login_page.dart`
+
+```dart
+class _LoginPageState extends ConsumerState<LoginPage> {
+  bool _rememberMe = false;  // Default: unchecked
+
+  // Checkbox UI
+  Checkbox(
+    value: _rememberMe,
+    onChanged: (value) {
+      setState(() {
+        _rememberMe = value ?? false;
+      });
+    },
+  ),
+
+  // Pass rememberMe to login
+  final success = await ref.read(authProvider.notifier).login(
+    email: _emailController.text.trim(),
+    password: _passwordController.text,
+    rememberMe: _rememberMe,  // ✅ Pass the value
+  );
+}
+```
+
+### 2. Auth Provider
+
+**File**: `lib/features/auth/presentation/providers/auth_provider.dart`
+
+```dart
+/// Login user
+Future<bool> login({
+  required String email,
+  required String password,
+  bool rememberMe = false,  // ✅ Accept rememberMe parameter
+}) async {
+  final result = await _repository.login(
+    email: email,
+    password: password,
+    rememberMe: rememberMe,  // ✅ Pass to repository
+  );
+  // ... rest of logic
+}
+```
+
+### 3. Auth Repository Interface
+
+**File**: `lib/features/auth/domain/repositories/auth_repository.dart`
+
+```dart
+abstract class AuthRepository {
+  Future<Either<Failure, AuthResponse>> login({
+    required String email,
+    required String password,
+    bool rememberMe = false,  // ✅ Added parameter
+  });
+}
+```
+
+### 4. Auth Repository Implementation
+
+**File**: `lib/features/auth/data/repositories/auth_repository_impl.dart`
+
+```dart
+@override
+Future<Either<Failure, AuthResponse>> login({
+  required String email,
+  required String password,
+  bool rememberMe = false,
+}) async {
+  try {
+    final authResponse = await remoteDataSource.login(loginDto);
+
+    // ✅ Conditional token saving based on rememberMe
+    if (rememberMe) {
+      await secureStorage.saveAccessToken(authResponse.accessToken);
+      print('Token saved to secure storage (persistent)');
+    } else {
+      print('Token NOT saved (session only)');
+    }
+
+    // Always set token for current session
+    dioClient.setAuthToken(authResponse.accessToken);
+
+    return Right(authResponse);
+  } catch (e) {
+    // Error handling
+  }
+}
+```
+
+---
+
+## User Experience
+
+### Scenario 1: Remember Me Enabled
+
+1. **User opens app** → Sees login page
+2. **User enters credentials** → Checks "Remember me"
+3. **User clicks Login** → Logs in successfully
+4. **User uses app** → All features work
+5. **User closes app completely**
+6. **User reopens app next day** → **Automatically logged in!** ✅
+7. No need to enter credentials again
+
+### Scenario 2: Remember Me Disabled
+
+1. **User opens app** → Sees login page
+2. **User enters credentials** → Does NOT check "Remember me"
+3. **User clicks Login** → Logs in successfully
+4. **User uses app** → All features work
+5. **User closes app completely**
+6. **User reopens app** → **Shows login page** ✅
+7. User must enter credentials again
+
+---
+
+## Security Considerations
+
+### Secure Storage
+- iOS: Uses **Keychain** (encrypted, secure)
+- Android: Uses **EncryptedSharedPreferences** (encrypted)
+- Token is encrypted at rest on device
+
+### Session-Only Mode
+- When Remember Me is disabled, token only exists in memory
+- Token cleared when app closes
+- More secure for shared/public devices
+
+### Best Practices
+- ✅ Tokens stored in secure storage (not plain SharedPreferences)
+- ✅ User controls persistence via checkbox
+- ✅ Token cleared on logout (always)
+- ✅ Session expires based on backend JWT expiration
+
+---
+
+## Testing the Feature
+
+### Test 1: Remember Me Enabled
+```
+1. Open app
+2. Login with Remember Me CHECKED
+3. Close app completely (swipe from recent apps)
+4. Reopen app
+Expected: Automatically logged in to MainScreen
+```
+
+### Test 2: Remember Me Disabled
+```
+1. Open app
+2. Login with Remember Me UNCHECKED
+3. Close app completely
+4. Reopen app
+Expected: Shows LoginPage, must login again
+```
+
+### Test 3: Logout Clears Token
+```
+1. Login with Remember Me CHECKED
+2. Close and reopen app (should auto-login)
+3. Go to Settings → Logout
+4. Close and reopen app
+Expected: Shows LoginPage (token was cleared)
+```
+
+### Test 4: Toggle Behavior
+```
+1. Login with Remember Me UNCHECKED
+2. Close and reopen (shows login)
+3. Login again with Remember Me CHECKED
+4. Close and reopen
+Expected: Auto-logged in (token now saved)
+```
+
+---
+
+## Debug Logs
+
+When you login, you'll see these logs:
+
+### Remember Me = true
+```
+🔐 Repository: Starting login (rememberMe: true)...
+🔐 Repository: Got response, token length=xxx
+🔐 Repository: Token saved to secure storage (persistent)
+🔐 Repository: Token set in DioClient
+```
+
+### Remember Me = false
+```
+🔐 Repository: Starting login (rememberMe: false)...
+🔐 Repository: Got response, token length=xxx
+🔐 Repository: Token NOT saved (session only - rememberMe is false)
+🔐 Repository: Token set in DioClient
+```
+
+---
+
+## Token Lifecycle
+
+### With Remember Me Enabled
+```
+Login → Token saved to SecureStorage + DioClient
+  ↓
+App running → Token in DioClient (API calls work)
+  ↓
+App closed → Token in SecureStorage (persisted)
+  ↓
+App opened → Token loaded from SecureStorage → Set in DioClient
+  ↓
+Auto-login → User sees MainScreen
+```
+
+### Without Remember Me
+```
+Login → Token ONLY in DioClient (not saved)
+  ↓
+App running → Token in DioClient (API calls work)
+  ↓
+App closed → Token lost (not persisted)
+  ↓
+App opened → No token in SecureStorage
+  ↓
+Shows LoginPage → User must login again
+```
+
+---
+
+## Files Modified
+
+1. ✅ `lib/features/auth/presentation/pages/login_page.dart`
+   - Pass `rememberMe: _rememberMe` to login method
+
+2. ✅ `lib/features/auth/presentation/providers/auth_provider.dart`
+   - Added `bool rememberMe = false` parameter to login method
+
+3. ✅ `lib/features/auth/domain/repositories/auth_repository.dart`
+   - Added `bool rememberMe = false` parameter to login signature
+
+4. ✅ `lib/features/auth/data/repositories/auth_repository_impl.dart`
+   - Conditional token saving: `if (rememberMe) { save token }`
+
+---
+
+## Common Questions
+
+### Q: What's the default behavior?
+**A**: Default is `rememberMe = false` (unchecked). User must explicitly check the box to enable.
+
+### Q: Is it secure?
+**A**: Yes! Tokens are stored in platform-specific secure storage (Keychain on iOS, EncryptedSharedPreferences on Android).
+
+### Q: What happens on logout?
+**A**: Logout always clears the token from secure storage, regardless of Remember Me state.
+
+### Q: Does the token expire?
+**A**: Yes, tokens expire based on your backend JWT configuration. When expired, user must login again.
+
+### Q: Can I change the default to checked?
+**A**: Yes, change `bool _rememberMe = false;` to `bool _rememberMe = true;` in login_page.dart.
+
+---
+
+## Summary
+
+✅ **Remember Me checkbox** is now functional
+✅ **Token persistence** controlled by user preference
+✅ **Secure storage** used for token encryption
+✅ **Session-only mode** available for shared devices
+✅ **Debug logging** shows token save/skip behavior
+
+The Remember Me feature is complete and ready to use! 🚀

+❌ No token found in storage
+🚀 isAuthenticated result: false
+❌ No token found, user needs to login
+AuthWrapper build: isAuthenticated=false, isLoading=false
+```
+
+**Result**: ✅ Should show LoginPage (must login again)
+
+---
+
+## Troubleshooting Guide
+
+### Issue 1: No initialization logs
+
+**Symptom**: Don't see `📱 RetailApp: initState called`
+
+**Cause**: Hot reload ('r') instead of hot restart ('R')
+
+**Fix**: Press 'R' (capital R) in terminal, not 'r'
+
+---
+
+### Issue 2: Token not being saved
+
+**Symptom**: See `🔐 Repository: Token NOT saved (session only)`
+
+**Cause**: Remember Me checkbox was not checked
+
+**Fix**: Make sure checkbox is checked before login
+
+---
+
+### Issue 3: Token saved but not loaded
+
+**Symptom**:
+- Login shows: `💾 SecureStorage: Token saved successfully`
+- Restart shows: `💾 SecureStorage: Token read result - exists: false`
+
+**Possible Causes**:
+1. Hot reload instead of hot restart
+2. Different SecureStorage instances (should not happen with keepAlive)
+3. Platform-specific secure storage issue
+
+**Debug**:
+```dart
+// Add this temporarily to verify token persistence
+// In lib/features/auth/presentation/pages/login_page.dart
+// After successful login, add:
+Future.delayed(Duration(seconds: 1), () async {
+  final storage = SecureStorage();
+  final token = await storage.getAccessToken();
+  print('🔬 TEST: Token check after 1 second: ${token != null}');
+});
+```
+
+---
+
+### Issue 4: Initialize not being called
+
+**Symptom**: No `🚀 Initializing auth state...` log
+
+**Cause**: `initState()` not being called or postFrameCallback not executing
+
+**Fix**: Verify app.dart has:
+```dart
+@override
+void initState() {
+  super.initState();
+  print('📱 RetailApp: initState called');  // Should see this
+  WidgetsBinding.instance.addPostFrameCallback((_) {
+    print('📱 RetailApp: Calling initialize()...');  // Should see this
+    ref.read(authProvider.notifier).initialize();
+  });
+}
+```
+
+---
+
+## Complete Log Sequence (Success Case)
+
+### On Login (Remember Me = true)
+```
+1. REQUEST[POST] => PATH: /auth/login
+2. 📡 DataSource: Calling login API...
+3. 🔐 Repository: Starting login (rememberMe: true)...
+4. 💾 SecureStorage: Saving token (length: 247)...
+5. 💾 SecureStorage: Token saved successfully
+6. 💾 SecureStorage: Verification - token exists: true, length: 247
+7. 🔐 Repository: Token saved to secure storage (persistent)
+8. ✅ Login SUCCESS
+9. AuthWrapper build: isAuthenticated=true
+```
+
+### On App Restart (Auto-Login)
+```
+1. 📱 RetailApp: initState called
+2. 📱 RetailApp: Calling initialize()...
+3. 🚀 Initializing auth state...
+4. 🔍 Checking authentication...
+5. 💾 SecureStorage: Checking if token exists...
+6. 💾 SecureStorage: Reading token...
+7. 💾 SecureStorage: Token read result - exists: true, length: 247
+8. 🔍 Has token in storage: true
+9. ✅ Token loaded from storage and set in DioClient
+10. 🚀 Token found, fetching user profile...
+11. ✅ Profile loaded: Admin User
+12. ✅ Initialize complete: isAuthenticated=true
+13. AuthWrapper build: isAuthenticated=true
+```

+## What to Share
+
+If auto-login is still not working, please share:
+
+1. **Complete logs from login** (Step 1)
+2. **Complete logs from restart** (Step 2)
+3. **Platform** (iOS, Android, macOS, web, etc.)
+
