5. xcode与cocoapods安装

对于 macOS 桌面开发，除了 Flutter SDK 之外，您还需要以下内容：

• Xcode
• CocoaPods如果你使用插件

2.打包发布.dmg

1.打包macos应用

flutter build macos --release 

2.创建.dmg文件

安装 create-dmg shell脚本，执行如下指令：

1.  
   #!/bin/sh
2.  
   test -f Application-Installer.dmg && rm Application-Installer.dmg
3.  
   create-dmg \
4.  
   --volname "Application Installer" \
5.  
   --volicon "application_icon.icns" \
6.  
   --background "installer_background.png" \
7.  
   --window-pos 200 120 \
8.  
   --window-size 800 400 \
9.  
   --icon-size 100 \
10.  
    --icon "Application.app" 200 190 \
11.  
    --hide-extension "Application.app" \
12.  
    --app-drop-link 600 185 \
13.  
    "Application-Installer.dmg" \
14.  
    "source_folder/"
15.  
     
16.  
    #"Application-Installer.dmg"是.dmg文件名称。
17.  
    #"source_folder/"是"flutter build macos --release"结果路径，如：/工程目录/build/macos/Build/Products/Release/xxx.app

3.产物.dmg

最终会在工程目录下生成 Application-Installer.dmg 文件，大功告成！注：打包发布都要cd到工程目录。
