## Overview

Lonewolf appears to be a Flutter travel-planning app: its screens and models cover destinations, journeys, hotels, experiences, reviews, payments, and user accounts. The likely user workflow is to explore places, plan a trip, arrange travel activities or accommodation, and manage the account. The README is only a Flutter starter template, and no Dart source was excerpted, so links between app screens, services, and data are tentative; dashed edges mark those inferred relationships. The Windows runner’s startup and window-hosting relationships are supported by the excerpts.

Main entry points: [`windows/runner/flutter_window.cpp`](https://github.com/srikantha129/lonewolf-travel-app/blob/master/windows/runner/flutter_window.cpp) (Flutter window host), [`windows/runner/main.cpp`](https://github.com/srikantha129/lonewolf-travel-app/blob/master/windows/runner/main.cpp) (Windows startup), [`lib/pages/explore`](https://github.com/srikantha129/lonewolf-travel-app/tree/master/lib/pages/explore) (Explore destinations), [`lib/pages/places`](https://github.com/srikantha129/lonewolf-travel-app/tree/master/lib/pages/places) (Places and recommendations)
