When i was debugging why widgets are building again and again, and found this issue.

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    print('Inside build');
    return MaterialApp( home: Container(child: Text('Hello World')));
 }
}

Output: flutter: Inside build

flutter: Inside build

Can someone explain why it printed twice? is it really rebuilding the MyApp() twice?
