## Overview

This repository combines a dairy-records Flutter app with a FastAPI backend. The backend supports farmer registration and login, PIN changes, authenticated record synchronization, and incremental reads of cows, milk, and milk-use records, stored in MariaDB. The likely user workflow is to use the app to manage farm records and sync them through the API; the Dart client source was not sampled, so its screens and API calls cannot be verified. Native platform hosts are runtime scaffolding rather than separate product features.

Main entry points: [`dairy_app/lib/main.dart`](https://github.com/muthomibenedict95-sys/dairyapp/blob/main/dairy_app/lib/main.dart) (Dairy app), [`dairy_app/windows/runner/flutter_window.cpp`](https://github.com/muthomibenedict95-sys/dairyapp/blob/main/dairy_app/windows/runner/flutter_window.cpp) (Windows Flutter host), [`backend/main.py`](https://github.com/muthomibenedict95-sys/dairyapp/blob/main/backend/main.py) (Farmer authentication), [`dairy_app/linux/runner/my_application.cc`](https://github.com/muthomibenedict95-sys/dairyapp/blob/main/dairy_app/linux/runner/my_application.cc) (Linux Flutter host)
