[Flutter] show Performance Overlay

MaterialApp 에 

 

show Performance Overlay: true, 추가해주면 앱 실행시 퍼포먼스 체크 할 수 있다!

 

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      title: 'Flutter Demo',
      showPerformanceOverlay: true,
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}
