## Overview

This is a small Flutter quiz application. Its apparent user journey is welcome, category selection, quiz configuration, answering questions, and viewing results, with quiz-session state and settings as internal support. The README is only a Flutter starter template, and no Dart source excerpts were provided; screen names support these stages, but their navigation and state wiring cannot be verified, so no inter-screen or state-access edges are asserted.

Main entry points: [`lib/main.dart`](https://github.com/tanvirahamedfoysal/quizzical/blob/main/lib/main.dart) (App entry)
