DITrix Attendance Scanner

DITrix Attendance Scanner is an open-source Flutter app I built to help my section, DIT 1-5, make attendance checking faster and easier. It also serves as my learning experience as a developer.

What it does

• Scan student IDs with the device camera
• Extract Student ID and surname via on-device OCR (ML Kit) with normalization for common OCR mistakes
• Manage attendance by sessions (subject, time-in, dismiss)
• Load a masterlist (CSV), mark present/late, and export results (CSV/XLSX)
• Dark/Light theme with a subtle green gradient
• Optional Developer Mode to view debug logs and diagnostics

Key features

• Session-based saving (each Capture ID session is persisted and resumable)
• Robust ID parsing (e.g., 2021-123456-MN-1 with common OCR corrections)
• Exports to CSV/XLSX into a DITrix attendance folder (with fallbacks)
• Onboarding tutorial (skippable)
• Settings for Theme (System/Light/Dark) and Developer Mode

Build

• Get packages and analyze:
  • flutter pub get
  • dart analyze
• Android release (AAB/APK):
  • flutter build appbundle --release
  • flutter build apk --release --split-per-abi
• Linux desktop (optional):
  • flutter build linux --release

Notes

• Camera and storage permissions are required for scanning and exports.
• This project is open source—feel free to explore, learn, and improve it.

Made to help DIT 1-5 and to grow my experience as a developer.
