## Overview

This is a Flutter expense-tracking app: its visible product modules cover expenses, categories, transaction types, persistence, and an expense-entry interface. The sampled files show only desktop runner startup and window hosting; no README or Dart excerpts establish the app’s runtime data flow, so those connections are left out. The graph includes the platform runner components identified as core by the source index, but does not infer how the unsampled Dart modules call one another.

Main entry points: [`windows/runner/flutter_window.h`](https://github.com/lorenzi-04/app-gestor-de-gastos/blob/main/windows/runner/flutter_window.h) (Flutter window), [`windows/runner/main.cpp`](https://github.com/lorenzi-04/app-gestor-de-gastos/blob/main/windows/runner/main.cpp) (Windows startup), [`linux/runner/main.cc`](https://github.com/lorenzi-04/app-gestor-de-gastos/blob/main/linux/runner/main.cc) (Linux startup), [`windows/runner/win32_window.cpp`](https://github.com/lorenzi-04/app-gestor-de-gastos/blob/main/windows/runner/win32_window.cpp) (Win32 window)
