记录一些真机调试flutter遇到的坑。
1、遇到一个签名错误，开始以为是非开发者账号的问题，但是新建了一个原生demo还是报错，各种Google，说什么key chain,build settings,没有一个能解决。
CodeSign /Volumes/HDD/OpenFrameworks/of_v0.9.8_osx_release/apps/plus-pool-light/pplight-ofx-098/bin/pplight-ofx-098Debug.app (in target ‘pplight-ofx-098’ from project ‘pplight-ofx-098’)

Command CodeSign failed with a nonzero exit code
苦了四天，最后找到了解决方案：
I fixed this by adding –deep to Other Code Signing Flags in the Build Settings > Signing
系统版本：10.15.7 MacOs catalina
Xcode版本：Version 12.1
