Task Notes Manager A simple Flutter app for managing tasks and notes with local persistence, theme toggling, and CRUD operations. Description This app allows users to: • View a dynamic list of tasks/notes on the home screen. • Add new tasks/notes via a form with validation (title, priority, description, completion status). • Toggle between light and dark themes, with preferences saved across app restarts. • Persist data using SQFLite (SQLite) for offline access—data survives app closes/restarts. Built as a Flutter tutorial project demonstrating navigation, forms, data modeling, JSON serialization, SharedPreferences, and SQFLite. Features • Home Screen: Welcome message, theme toggle switch, dynamic ListView of tasks (fetched from DB), FAB to add new items. • Add Screen: Form with TextFields, Dropdown for priority (Low/Medium/High), Checkbox for completion, Submit button that saves to DB. • Persistence: Themes via SharedPreferences; tasks via SQFLite (insert, retrieve all). • Bonus: Database includes delete method (not yet integrated in UI). • Theme Support: Automatic light/dark mode based on user preference.

Tech Stack

• Flutter: UI framework (Dart language). • Packages: ◦ shared_preferences: ^2.3.0 (theme persistence). ◦ sqflite: ^2.3.3 + path: ^1.9.0 (local SQLite DB). • Data Model: TaskItem class with toJson() and fromJson() for serialization. • Database: Singleton DatabaseHelper for init/insert/getAll/delete tasks. • IDE: Android Studio. Installation & Setup 1 Clone/Setup Project:git clone 2 cd task_notes_manager 3 4 Flutter Setup: ◦ Ensure Flutter SDK is installed: flutter.dev/docs/get-started/install. ◦ Run flutter doctor to verify (fix any issues). 5 Dependencies:flutter pub get 6 7 Run the App: ◦ Start an emulator/device: Tools > AVD Manager in Android Studio. ◦ Run: flutter run (or green ▶ button in IDE). ◦ For web: flutter run -d chrome (enable web if needed: flutter config --enable-web). Usage 1 Launch the app → Home screen shows empty list (or existing tasks). 2 Toggle “Dark Mode” switch → Theme changes and persists on restart. 3 Tap + FAB → Navigate to Add screen. 4 Fill form (title required, description required, pick priority, optional completed) → Tap Submit. 5 Back to Home → New task appears in list with details (priority, description, checkmark if completed). 6 Data persists: Close/reopen app → Tasks and theme remain.
