使用 English words 包生成文本来替换字符串“Hello World”.
Tip: “驼峰命名法” (称为 “upper camel case” 或 “Pascal case” ), 表示字符串中的每个单词(包括第一个单词)都以大写字母开头。所以，“uppercamelcase” 变成 “UpperCamelCase”
进行以下更改, 如高亮部分所示:
import 'package:flutter/material.dart';
import 'package:english_words/english_words.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
final wordPair = new WordPair.random();
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'),
child: new Text(wordPair.asPascalCase),
),
),
);
}
}
