Flutter学习一：最简单的Flutter应用

import 'package:flutter/material.dart';

void main() {
  //顶层容器，相当于rootview
  runApp(
    //Center为容器，展示控件为Text 需要添加TextDirection
    new Center(
      child: new Text(
        "Flutter",
        textDirection: TextDirection.rtl,
      ),
    ),
  );
}

需要设置pubspec.yaml中

uses-material-design: true
