# Flutter - 第一個APP(官網:隨機公司名稱)

## 建立專案(VSCode 開發)
1. 建立新專案 Application

2. 删除 lib/main.dart 內 所有文字改為以下

    // Copyright 2018 The Flutter team. All rights reserved.
    // Use of this source code is governed by a BSD-style license that can be
    // found in the LICENSE file.

    import 'package:flutter/material.dart';

    void main() {
      runApp(const MyApp());
    }

    class MyApp extends StatelessWidget {
      const MyApp({Key? key}) : super(key: key);

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

3. 運行(連上手機或開模擬器都可，**手機首次建立會需要幾分鐘**)

    flutter run


terminal 輸入小寫`r`可進行hot reload

## 使用外部 package
1. 下載外部套件

    flutter pub add english_words

安裝完後就會看到pubspec.yaml文件內這一個依賴項已添加

2. import

    import 'package:english_words/english_words.dart';

3. 簡單測試(隨機改變背景文字)
