## Overview

This is a Flutter application whose Dart sources indicate a collection of student utilities: CGPA calculation, course cards, a course page, maps, routines, study timing, and weather tables. The likely user workflow is to launch the app and use these screens, but the generic README and unavailable Dart excerpts do not establish navigation or calls between them. The graph therefore shows the identifiable app modules and sampled native launch/hosting code without inventing a screen flow.

Main entry points: [`windows/runner/flutter_window.h`](https://github.com/baustcse/hello-flutter/blob/main/windows/runner/flutter_window.h) (Flutter window), [`linux/runner/main.cc`](https://github.com/baustcse/hello-flutter/blob/main/linux/runner/main.cc) (Linux entry), [`windows/runner/main.cpp`](https://github.com/baustcse/hello-flutter/blob/main/windows/runner/main.cpp) (Windows entry), [`linux/runner/my_application.h`](https://github.com/baustcse/hello-flutter/blob/main/linux/runner/my_application.h) (Linux app host)
