## Overview

This is a small Flutter vending-machine app, but the README is only Flutter starter-project guidance and the supplied source excerpts contain no Dart code. The tree suggests home, transaction, and admin screens, plus item, stock, and presentation modules; their exact runtime wiring and user-to-result flow cannot be confirmed, so no interactions are asserted.
