I need a complete face-recognition attendance application built with Flutter, released first on Google Play and architected so the same codebase can later be published on the App Store. The system will be used by employees and must recognise faces in real time; once someone is marked present, an Excel-format attendance report should be generated automatically and e-mailed through Gmail to the addresses I configure. The flow I have in mind is straightforward: launch the app, the camera opens, the employee’s face is recognised instantly, their timestamp is stored, and at the end of each day (or on demand) the XLSX sheet is compiled and sent out. If you prefer leveraging Google APIs or direct SMTP for the mail send, that is fine as long as it works seamlessly with standard Gmail accounts. Please deliver: • Flutter source code with clear setup instructions • A signed, ready-to-upload Android build (AAB) for the Play Store • Automated Excel generation and Gmail email workflow fully wired and tested Clean, readable Dart code and concise documentation are essential so we can extend the project to iOS later on.
