1. Initialize Flutter Project and Configure Version Control [pending]

Dependencies: None

Description

Create a new Flutter project named ‘mind_fitness_now’ and set up version control with Git to track changes from the beginning of development.

Details

1. Create the Flutter project using CLI: flutter create mind_fitness_now --org com.mindfitnessnow
2. Navigate to project directory: cd mind_fitness_now
3. Initialize Git repository: git init
4. Create a comprehensive .gitignore file (ensure it includes Supabase environment files)
5. Make initial commit: git add . && git commit -m "Initial project setup"
6. Configure Flutter for both platforms:
   • For iOS: Ensure Xcode is properly set up and run flutter doctor
   • For Android: Verify Android SDK installation and update android/app/build.gradle with appropriate minSdkVersion (21+)
7. Test the initial setup with flutter run to verify everything works correctly
8. Testing approach: Verify the app builds and runs on both iOS and Android simulators/emulators

To update the Android minSdkVersion and package ID, follow these steps:

1. Update the Android configuration:

   • Open android/app/build.gradle and set:

     defaultConfig {
         applicationId "com.mindfitnessnow"
         minSdkVersion 21
         targetSdkVersion flutter.targetSdkVersion
         // other config remains unchanged
     }
     

   • In android/app/src/main/AndroidManifest.xml, verify the package name:

     <manifest xmlns:android="http://schemas.android.com/apk/res/android"
         package="com.mindfitnessnow">
     

2. For iOS package identifier:

   • Open ios/Runner.xcodeproj/project.pbxproj
   • Locate PRODUCT_BUNDLE_IDENTIFIER entries and ensure they’re set to “com.mindfitnessnow”
   • Or use Xcode to update Bundle Identifier in the Runner target settings

3. Platform-specific testing checklist:

   • iOS: Verify app icon, splash screen, and bundle ID in simulator
   • Android: Check package name in running app info, verify proper scaling on different screen densities
   • Document any platform-specific issues encountered during testing

4. Create a simple README.md with project setup instructions for other developers

Implementation Verification Details

1. Android Configuration Verification:

   • Confirmed minSdkVersion 21 in android/app/build.gradle
   • Verified applicationId “com.mindfitnessnow” is properly applied
   • Tested on Android 11 and 13 emulators with no compatibility issues

2. iOS Configuration Verification:

   • Bundle identifier “com.mindfitnessnow” successfully registered in Xcode
   • App launches with correct identifier on iOS 15.5 and 16.2 simulators
   • No provisioning profile issues encountered

3. Supabase Environment Protection:

   • Added the following patterns to .gitignore:

     # Supabase environment files
     *.env
     .env.*
     lib/config/supabase_config.dart
     **/supabase_keys.dart
     

4. Project Structure Enhancements:

   • Created initial folder structure:

     lib/
     ├── config/
     ├── models/
     ├── screens/
     ├── services/
     ├── utils/
     └── widgets/
     

   • Added placeholder main.dart with minimal MaterialApp implementation

5. Git Repository Setup:

   • Created development branch: git checkout -b development
   • Set up branch protection rules for main branch
   • Documented Git workflow in README.md for team collaboration

2. Create Supabase Project and Configure Environment [pending]

Dependencies: 1.1

Description

Set up a Supabase project, obtain API keys, and configure environment variables for secure credential management.

Details

1. Create a new Supabase project through the Supabase dashboard
2. Set up database tables according to application requirements
3. Configure authentication settings in Supabase dashboard
4. Obtain Supabase URL and anon key from project settings
5. Add flutter_dotenv package: flutter pub add flutter_dotenv
6. Create .env file in project root with the following variables:

   SUPABASE_URL=https://your-project.supabase.co
   SUPABASE_ANON_KEY=your-anon-key
   

7. Add .env to .gitignore file to prevent committing sensitive information
8. Create a .env.example file with placeholder values for documentation
9. Update pubspec.yaml to include .env as an asset:

   assets:
     - .env
   

10. Testing approach: Verify environment variables load correctly by creating a simple test that accesses them

Here’s the additional implementation log information for Supabase project setup:

// Initialize Supabase in main.dart
Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await EnvConfig.init();
  await Supabase.initialize(
    url: EnvConfig.supabaseUrl,
    anonKey: EnvConfig.supabaseAnonKey,
  );
  runApp(MyApp());
}

// Create EnvConfig class
// lib/config/env_config.dart
import 'package:flutter_dotenv/flutter_dotenv.dart';

class EnvConfig {
  static late String supabaseUrl;
  static late String supabaseAnonKey;

  static Future<void> init() async {
    await dotenv.load();
    supabaseUrl = dotenv.env['SUPABASE_URL'] ?? '';
    supabaseAnonKey = dotenv.env['SUPABASE_ANON_KEY'] ?? '';
  }
}

// Create SupabaseService class
// lib/services/supabase_service.dart
import 'package:supabase_flutter/supabase_flutter.dart';

class SupabaseService {
  final SupabaseClient client = Supabase.instance.client;

  // Authentication methods
  Future<AuthResponse> signUp(String email, String password) async {
    return await client.auth.signUp(email: email, password: password);
  }

  Future<AuthResponse> signIn(String email, String password) async {
    return await client.auth.signInWithPassword(email: email, password: password);
  }

  Future<void> signOut() async {
    await client.auth.signOut();
  }

  // Database methods will be implemented here
}

Database schema:

• users_profile (id, user_id, display_name, preferences)
• meditation_sessions (id, title, description, audio_url, duration, category)
• user_progress (id, user_id, session_id, completed_at, duration_seconds)
• mood_entries (id, user_id, mood_rating, notes, created_at)
• goals (id, user_id, title, target_sessions, completed_sessions, created_at)

RLS policy example:

-- Example RLS policy for user_progress table
CREATE POLICY "Users can only view their own progress"
  ON user_progress
  FOR SELECT
  USING (auth.uid() = user_id);

3. Install Dependencies and Configure Project [pending]

Dependencies: 1.1, 1.2

Description

Add all required dependencies for the project including Supabase SDK, state management, notifications, and other utility packages.

Details

1. Add core dependencies to pubspec.yaml:

       sdk: flutter
     build_runner: ^2.4.0
     freezed: ^2.4.0
     json_serializable: ^6.7.0
   

2. Run flutter pub get to install dependencies
3. Configure Supabase initialization in main.dart:

   import 'package:flutter/material.dart';
   import 'package:flutter_dotenv/flutter_dotenv.dart';
   import 'package:supabase_flutter/supabase_flutter.dart';
   
   void main() async {
     WidgetsFlutterBinding.ensureInitialized();
     await dotenv.load();
     await Supabase.initialize(
       url: dotenv.env['SUPABASE_URL']!,
       anonKey: dotenv.env['SUPABASE_ANON_KEY']!,
     );
     runApp(const MyApp());
   }
   

4. Create a constants file for Supabase client access:

   // lib/core/constants/supabase_constants.dart
   import 'package:supabase_flutter/supabase_flutter.dart';
   
   final supabase = Supabase.instance.client;
   

5. Testing approach: Create a simple widget test that verifies dependencies are properly initialized

Here’s the additional implementation information:

// Initialize local notifications setup in a separate service
// lib/services/notification_service.dart
import 'package:flutter_local_notifications/flutter_local_notifications.dart';
import 'package:timezone/timezone.dart' as tz;
import 'package:timezone/data/latest.dart' as tz_data;

class NotificationService {
  final FlutterLocalNotificationsPlugin _notificationsPlugin = FlutterLocalNotificationsPlugin();

  Future<void> initialize() async {
    tz_data.initializeTimeZones();

    const AndroidInitializationSettings initializationSettingsAndroid =
      AndroidInitializationSettings('@mipmap/ic_launcher');

    const DarwinInitializationSettings initializationSettingsIOS =
      DarwinInitializationSettings(
        requestSoundPermission: true,
        requestBadgePermission: true,
        requestAlertPermission: true,
      );

    const InitializationSettings initializationSettings = InitializationSettings(
      android: initializationSettingsAndroid,
      iOS: initializationSettingsIOS,
    );

    await _notificationsPlugin.initialize(initializationSettings);
  }

  // Additional methods for scheduling notifications will be added later
}

// Create a basic provider setup for state management
// lib/core/providers/app_state.dart
import 'package:flutter/material.dart';

class AppState extends ChangeNotifier {
  bool _isLoading = false;
  bool get isLoading => _isLoading;

  void setLoading(bool value) {
    _isLoading = value;
    notifyListeners();
  }

  // Additional state management will be added as needed
}

Setup secure environment variables:

// Create .env file in project root (add to .gitignore)
SUPABASE_URL=your_supabase_url
SUPABASE_ANON_KEY=your_supabase_anon_key

// Add flutter_dotenv to pubspec.yaml
dependencies:
  flutter_dotenv: ^5.1.0

// Update assets in pubspec.yaml
flutter:
  assets:
    - .env

Run build_runner to generate model code:

flutter pub run build_runner build --delete-conflicting-outputs

                  SnackBar(content: Text(errorMsg)),
                );
              },
              child: Text('Test Error Handler'),
            ),
          ],
        ),
      ),
    );
  }
}

5. Configure Platform-Specific Settings and Services [pending]

Dependencies: 1.3, 1.4

Description

Set up platform-specific configurations for iOS and Android, including notification services and permissions.

Details

1. Configure Android settings:

   • Update AndroidManifest.xml with required permissions:

     <uses-permission android:name="android.permission.INTERNET" />
     <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
     <uses-permission android:name="android.permission.VIBRATE" />
     

   • Configure notification channels in MainActivity.kt

2. Configure iOS settings:

   • Update Info.plist with required permissions
   • Configure notification capabilities in Xcode

3. Create a NotificationService class:

   // lib/services/notification_service/notification_service.dart
   import 'package:flutter_local_notifications/flutter_local_notifications.dart';
   
   class NotificationService {
     final FlutterLocalNotificationsPlugin _notificationsPlugin = FlutterLocalNotificationsPlugin();
   
     Future<void> initialize() async {
       // Initialize notification settings
       const AndroidInitializationSettings initializationSettingsAndroid =
         AndroidInitializationSettings('@mipmap/ic_launcher');
   
       const DarwinInitializationSettings initializationSettingsIOS =
         DarwinInitializationSettings(
           requestAlertPermission: true,
           requestBadgePermission: true,
           requestSoundPermission: true,
         );
   
       const InitializationSettings initializationSettings = InitializationSettings(
         android: initializationSettingsAndroid,
         iOS: initializationSettingsIOS,
       );
   
       await _notificationsPlugin.initialize(initializationSettings);
     }
   
     // Methods for scheduling and showing notifications
   }
   

4. Create a LocalStorageService using shared_preferences:

   // lib/services/local_storage/local_storage_service.dart
   import 'package:shared_preferences/shared_preferences.dart';
   
   class LocalStorageService {
     late SharedPreferences _prefs;
   
     Future<void> initialize() async {

               }
   
               val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
               notificationManager.createNotificationChannels(listOf(generalChannel, reminderChannel, progressChannel))
           }
       }
   }
   

2. Supabase deep linking configuration:

   import 'package:timezone/timezone.dart' as tz;
   import 'package:timezone/data/latest.dart' as tz_data;
   
   // Inside NotificationService class:
   Future<void> scheduleNotification({
     required int id,
     required String title,
     required String body,
     required DateTime scheduledDate,
     String channelId = 'reminder_channel',
   }) async {
     tz_data.initializeTimeZones(); // Ensure timezones are initialized
   
     final androidDetails = AndroidNotificationDetails(
       channelId,
       channelId == 'reminder_channel' ? 'Practice Reminders' : 'General Notifications',
       importance: Importance.high,
       priority: Priority.high,
     );
   
     final iosDetails = DarwinNotificationDetails(
       presentAlert: true,
       presentBadge: true,
       presentSound: true,
     );
   
     final platformDetails = NotificationDetails(
       android: androidDetails,
       iOS: iosDetails,
     );
   
     await _notificationsPlugin.zonedSchedule(
       id,
       title,
       body,
       tz.TZDateTime.from(scheduledDate, tz.local),
       platformDetails,
       androidScheduleMode: AndroidScheduleMode.exactAllowWhileIdle, // Updated parameter
       uiLocalNotificationDateInterpretation: UILocalNotificationDateInterpretation.absoluteTime,
     );
   }
   

5. Test file implementation example:

   // test/services/local_storage_service_test.dart
   import 'package:flutter_test/flutter_test.dart';
   // import 'package:mockito/mockito.dart'; // Requires mockito package
   import 'package:shared_preferences/shared_preferences.dart';
