🚀 Overview & My Journey

Attendance Manager is a project born out of necessity.

As 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.

In 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.

Now, 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.

✨ Key Features

• ⚡ Quick Actions: Mark attendance for a whole class in seconds.
• 📊 Dashboard: Real-time view of daily stats and shortcuts.
• 🔍 Smart Search: Instantly find student records by name or ID.
• 📂 Local Database: Powered by SQLite for instant loading and 100% offline access – a major upgrade from my previous web tool.
• 🛡️ Data Safety: Built-in Backup & Restore functionality (.db files).
• 🎓 Student Management: Add, edit, or delete student profiles and organize them by department.
• 📈 Analytics: View attendance percentages per student or per class.
• 💬 Message Generation: Auto-generate formatted absent messages for WhatsApp groups.
• 📤 Export Options: Generate HTML files for faculty to fill online registers or text summaries for daily reviews.

📂 Project Structure & File Guide

Here is a quick map of the codebase to help developers understand the purpose of each file:

Core

• main.dart: The entry point. Sets up the app theme, routes, and initializes the root widget.
• database/database_helper.dart: The "brain" of the app. Handles all SQLite operations (CRUD), table creation, and complex queries for reports.

Screens (UI)

• splash_screen.dart: The animated startup screen with the app logo.
• home_screen.dart: The main dashboard containing the "Take Attendance" button, daily summary widgets, and navigation grid.
• report_generator_v3.dart: The core screen for taking attendance. It allows CRs to toggle absentees and generate the final message.
• daily_report_screen.dart: Displays a visual summary of the day's attendance (Present vs Absent charts).
• search_screen.dart: A powerful analytics dashboard. Allows searching for students, sorting by "Defaulters" (low attendance), and viewing class performance.
• student_detail_screen.dart: Shows a 360° view of a specific student, including their overall percentage, subject-wise breakdown, and dates absent.
• custom_report_screen.dart: Allows users to select a date range and export detailed reports as HTML or Text.
• time_table_screen.dart: Manages the weekly class schedule and defines which subjects are Electives.
• manage_enrollment_screen.dart: Handles mapping students to specific elective subjects.
• student_input_screen.dart: Provides forms to add students manually or via a bulk text import feature.
• department_setup_screen.dart: A setup screen to configure department names (e.g., CE, IT) before adding students.
• backup_screen.dart: Interface for exporting the database file (.db) or restoring from a backup.
• about_me_screen.dart: A portfolio page displaying developer information and contact links.

Models

• student.dart, department.dart: Data models representing the database entities.
• student_report_models.dart: Helper models used to calculate and pass analytics data between screens.
