Hot reload is not working in a simple Hello World example. When trying to change the text, a string, to something else under run-time and hot reload it, nothing happens. I'm debugging on a physical device and I'm using VSCode.

import 'package:flutter/material.dart';

void main() {
  String text = "Hello world";
      runApp(Center(child: new Text(text, textDirection: TextDirection.ltr)));
}

  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {

    );
  }
}
