第一步创建 Flutrer APP

1.创建新应用

选择 File>New Flutter Project
选择 Flutter application 作为 project 类型, 然后点击 Next
输入项目名称 (如 myapp), 然后点击 Next
点击 Finish
等待Android Studio安装SDK并创建项目.

第二步编写Flutter应用

1.替换 lib/main.dart

删除lib所有代码，替换为一下代码,实现 Hello Word

import 'package:flutter/material.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Welcome to Flutter',
      home: new Scaffold(
        appBar: new AppBar(
          title: new Text('Welcome to Flutter'),
        ),
        body: new Center(
          child: new Text('Hello World'),
        ),
      ),
    );
  }
}
