0x01-1、2-1 Flutter開發環境的安裝-01：
0x01-2、2-1 Flutter開發環境的安裝-02：
0x02、JDK 安裝：
由於官網下載比較緩慢。可以下載我百度網盤的JDK：鏈接: https://pan.baidu.com/s/1ibnt4PnJgOwFjxNdI3l47Q 提取碼: v2jj 復制這段內容后打開百度網盤手機App，操作更方便哦；
Mac下如何安裝JDK：詳細過程可以參考：https://www.cnblogs.com/quickcodes/p/5127101.html
安裝好JDK后需要配置JDK的環境變量：請參考：Mac下如何配置環境變量
0x03、Flutter JDK 安裝：
由於官網下載比較緩慢。可以下載我百度網盤的Flutter SDK：https://pan.baidu.com/s/1OQLCy44KBbd1IoBuUzz1eQ
我的 `Flutter` 安裝在了如下路徑（`home`目錄下載新建一個`app`文件夾中）
-
配置環境變量:
-
在終端執行
opne ~/.bash_profile，加入Flutter的安裝路徑-
export PATH=/Users/mingo/app/flutter/bin:$PATH
-
保存關閉 執行：
source ~/.bash_profile
-
-
這個時候應該能運行flutter命令了，我們運行命令行：
flutter -h- 出現如下：
$ flutter -h

因為不需要使用 IntelliJ IDEA來開發，如果你電腦中沒有安裝IntelliJ IDEA是不會提示這個警告的，所以可以先不管這個欄目的❗️和 ❌
到此，Flutter 環境搭建完成，可以用 Android Studio，新建第一個 Flutter項目了。
