## Overview

Brick Breaker is a Flutter mobile Breakout game. The documented player workflow is to enter the game, control a paddle to bounce a ball and break walls, then progress through five levels. The repository also includes menu, configuration, and developer screens, plus game models and sound assets. Source excerpts cover only Android build configuration, so the graph follows documented product behavior and tree paths; internal call wiring beyond that is not verified.

Main entry points: [`flutter_application/lib/src/game/controllers/game_controller.dart`](https://github.com/julia-maia/brick-breaker/blob/main/flutter_application/lib/src/game/controllers/game_controller.dart) (Game controller), [`flutter_application/lib/src/views/game_brick_breaker.dart`](https://github.com/julia-maia/brick-breaker/blob/main/flutter_application/lib/src/views/game_brick_breaker.dart) (Game screen), [`flutter_application/lib/src/views/menu.dart`](https://github.com/julia-maia/brick-breaker/blob/main/flutter_application/lib/src/views/menu.dart) (Main menu), [`flutter_application/lib/main.dart`](https://github.com/julia-maia/brick-breaker/blob/main/flutter_application/lib/main.dart) (Flutter entry)
