## Overview

Usina App is a Flutter application whose visible product surface comprises login, a principal screen, and cadastro screens for users, units, equipment, harvests, indicators, measurements, and related information types. The likely user journey is to enter through login, reach the principal screen, and use a cadastro screen to manage domain records. The README provides no product-specific workflow details, and the Dart source was not sampled, so these UI transitions are shown as unverified. Platform runner excerpts establish how native hosts launch Flutter; they do not establish the Dart-side calls.

Main entry points: [`lib/screens/login_page.dart`](https://github.com/desmantelar-bit/usina-app/blob/main/lib/screens/login_page.dart) (Login), [`lib/screens/tela_principal.dart`](https://github.com/desmantelar-bit/usina-app/blob/main/lib/screens/tela_principal.dart) (Principal screen), [`lib/screens/cadastros`](https://github.com/desmantelar-bit/usina-app/tree/main/lib/screens/cadastros) (Cadastro screens), [`linux/runner/my_application.cc`](https://github.com/desmantelar-bit/usina-app/blob/main/linux/runner/my_application.cc) (Linux application)
