0x01-一、2-1 Flutter開發環境的安裝-01：

0x01-二、2-1 Flutter開發環境的安裝-02：

0x0二、JDK 安裝：

因爲官網下載比較緩慢。能夠下載我百度網盤的JDK：連接: https://pan.baidu.com/s/1ibnt4PnJgOwFjxNdI3l47Q 提取碼: v2jj 複製這段內容後打開百度網盤手機App，操做更方便哦；

Mac下如何安裝JDK：詳細過程能夠參考：http://www.javashuo.com/article/p-ohmavdnz-ee.html
安裝好JDK後須要配置JDK的環境變量：請參考：Mac下如何配置環境變量

0x0三、Flutter JDK 安裝：

因爲官網下載比較緩慢。能夠下載我百度網盤的Flutter SDK：https://pan.baidu.com/s/1OQLCy44KBbd1IoBuUzz1eQ

個人 Flutter 安裝在了以下路徑（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，咱們運行命令行：flutter -h
  • 出現以下：

$ flutter -h
Manage your Flutter app development.

Common commands:

  flutter create <output directory>

0x0四、Flutter 檢查環境：

0x04-一、Flutter 提供了 檢查環境 命令 flutter doctor

# mingo @ 192 in ~ [12:59:45]

如上：帶❌的就必須按照。帶❗️的就能夠暫時忽略。

0x04-二、安裝 Android Studio 和 VS Code

打開android studio, 打開plugins ,安裝flutter

輸入flutter搜索，點擊中間的 Search in repositories

點擊install,順利的話安裝完畢以後重啓android studio

再次運行

0x04-四、解決 iOS 環境

按照以下截圖，依次一個個執行如圖命令。

第六個命令 brew install ios-deploy 安裝完以下:

# mingo @ 192 in ~ [13:49:02] 
$ brew install ios-deploy
==> Downloading https://homebrew.bintray.com/bottles/ios-deploy-1.9.4.high_sierra.bottle.tar

由於不須要使用 IntelliJ IDEA來開發，若是你電腦中沒有安裝IntelliJ IDEA是不會提示這個警告的，因此能夠先無論這個欄目的❗️和 ❌

到此，Flutter 環境搭建完成，能夠用 Android Studio，新建第一個 Flutter項目了。
