使用vscode命令行创建flutter应用,ctril+alt+p打开命令行,选择Flutter:New Project创建应用,修改对应目录文件下的lib/main.dart文件如下所示:
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Welcome to Flutter',
home: Scaffold(
appBar: AppBar(
title: Text('Welcome to Flutter'),
),
body: Center(
child: Text('Hello World'),
),
),
);
}
}
命令行运行 flutter run 执行,可以看到在ISO simulator中出现hello world。
