  );
  
  runApp(MyApp());
}

// Access performance data
final controller = PerformanceMonitorController.instance;
controller.startMonitoring();

// Get current metrics
final currentFPS = controller.currentFPS;
final memoryUsage = controller.memoryUsageMB;
final isJanky = controller.isJanky;

// Listen to updates
