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：

#!/bin/sh
test -f Application-Installer.dmg && rm Application-Installer.dmg
create-dmg \
  --volname "Application Installer" \
  --volicon "application_icon.icns" \
  --background "installer_background.png" \
  --window-pos 200 120 \
  --window-size 800 400 \
  --icon-size 100 \
  --icon "Application.app" 200 190 \
  --hide-extension "Application.app" \
  --app-drop-link 600 185 \
  "Application-Installer.dmg" \
  "source_folder/"

#"Application-Installer.dmg"是.dmg文件名称。
#"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。
