  • @JoshuaChang run: `flutter doctor --android-licenses` . Also check your env variables. According to the error `C:\ is not a ...` appears like error in the path of Flutter sdk in env variables. – dev-aentgs Jun 24 '20 at 15:44

Just add a Scaffold as home: Scaffold and the Center as body: Center.

import 'package:flutter/material.dart';

void main() => runApp(MaterialApp(
      home: Scaffold(
        body: Center(
          child: Text('Hello World'),
        ),
      ),
    ),
);
