Fast. Reliable.**\n\u003e An offline-first mobile application designed to streamline the attendance process for Class Representatives (CRs) and faculty. Built with Flutter \u0026 SQLite.\n\n---\n\n## 🚀 Overview \u0026 My Journey\n\n**Attendance Manager** is a project born out of necessity.\n\nAs the **Class Representative (CR)** at RK University for the past two years, I have been responsible for taking attendance and generating absent messages for parent groups. Initially, I solved this by building a simple website using inline CSS and JavaScript. While it worked, it had limitations: no offline storage and no easy way to save logs.\n\nIn my **5th semester**, I learned Flutter as part of my curriculum and saw the perfect opportunity to upgrade my workflow. I built this app to replace my old website, adding **SQLite for offline access**, faster entry methods, and automated message generation.\n\nNow, when faculty ask for attendance reviews, I can instantly provide HTML files or text summaries directly from my phone. This project reflects my journey from basic web development to full-stack mobile engineering.\n\n## ✨ Key Features\n\n- **⚡ Quick Actions:** Mark attendance for a whole class in seconds.\n- **📊 Dashboard:** Real-time view of daily stats and shortcuts.\n- **🔍 Smart Search:** Instantly find student records by name or ID.\n- **📂 Local Database:** Powered by **SQLite** for instant loading and 100% offline access – a major upgrade from my previous web tool.\n- **🛡️ Data Safety:** Built-in **Backup \u0026 Restore** functionality (`.db` files).\n- **🎓 Student Management:** Add, edit, or delete student profiles and organize them by department.\n- **📈 Analytics:** View attendance percentages per student or per class.\n- **💬 Message Generation:** Auto-generate formatted absent messages for WhatsApp groups.\n- **📤 Export Options:** Generate HTML files for faculty to fill online registers or text summaries for daily reviews.\n\n---\n\n## 📸 App Tour \u0026 Screenshots\n\n### **1.

Sets up the app theme, routes, and initializes the root widget.\n- **`database/database_helper.dart`**: The \"brain\" of the app. Handles all SQLite operations (CRUD), table creation, and complex queries for reports.\n\n### **Screens (UI)**\n- **`splash_screen.dart`**: The animated startup screen with the app logo.\n- **`home_screen.dart`**: The main dashboard containing the \"Take Attendance\" button, daily summary widgets, and navigation grid.\n- **`report_generator_v3.dart`**: The core screen for taking attendance. It allows CRs to toggle absentees and generate the final message.\n- **`daily_report_screen.dart`**: Displays a visual summary of the day's attendance (Present vs Absent charts).\n- **`search_screen.dart`**: A powerful analytics dashboard. Allows searching for students, sorting by \"Defaulters\" (low attendance), and viewing class performance.\n- **`student_detail_screen.dart`**: Shows a 360° view of a specific student, including their overall percentage, subject-wise breakdown, and dates absent.\n- **`custom_report_screen.dart`**: Allows users to select a date range and export detailed reports as HTML or Text.\n- **`time_table_screen.dart`**: Manages the weekly class schedule and defines which subjects are Electives.\n- **`manage_enrollment_screen.dart`**: Handles mapping students to specific elective subjects.\n- **`student_input_screen.dart`**: Provides forms to add students manually or via a bulk text import feature.\n- **`department_setup_screen.dart`**: A setup screen to configure department names (e.g., CE, IT) before adding students.\n- **`backup_screen.dart`**: Interface for exporting the database file (`.db`) or restoring from a backup.\n- **`about_me_screen.dart`**: A portfolio page displaying developer information and contact links.\n\n### **Models**\n- **`student.dart`**, **`department.dart`**: Data models representing the database entities.\n- **`student_report_models.dart`**: Helper models used to calculate and pass analytics data between screens.\n\n---\n\n## 🛠️ Tech Stack\n\n- **Framework:** [Flutter](https://flutter.dev/) (Dart)\n- **Database:** SQLite (`sqflite`) – For offline attendance logs\n- **State Management:** Native (`setState`) \u0026 MVC Pattern\n- **Key Packages:**\n  - `flutter_native_splash` (Branding)\n  - `share_plus` (Sharing Messages \u0026 Exports)\n  - `path_provider` (File System Access)\n  - `intl` (Date Formatting)\n  - `file_picker` (Restoring Backups)\n\n---\n\n## 📲 Installation \u0026 Setup\n\n1.  **Clone the Repo**\n\n    ```bash\n    git clone [https://github.com/yashmakwana03/absent_message.git](https://github.com/yashmakwana03/absent_message.git)\n    ```\n\n2.  **Install Dependencies**\n\n    ```bash\n    flutter pub get\n    ```\n\n3.  **Run the App**\n    ```bash\n    flutter run\n    ```\n\n---\n\n## 👨‍💻 Developer\n\n**Yash Makwana**\n\n- 🎓 3rd Year Computer Science Student at RK University\n- 💼 Class Representative (CR)\n- 📧 [yashmakwana2275@gmail.com](mailto:yashmakwana2275@gmail.com)\n- 🔗 [LinkedIn Profile](https://www.linkedin.com/in/yashmakwana03/)\n\n\u003e _This app is a result of my real-world responsibilities as a CR. What started as a simple website evolved into a full-fledged mobile app thanks to Flutter. I believe in creating tools that make life easier for students, faculty, and myself._\n\n---\n\n_⭐ If you find this project useful, please give it a star on GitHub!_\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fyashmakwana03%2Fabsent_message","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fyashmakwana03%2Fabsent_message","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fyashmakwana03%2Fabsent_message/lists"}
