Flutter 运行报错

记录一下早上遇到的错误，代码运行昨晚明明没问题的，早上就报了这个错误

Could not build the precompiled application for the device.

It appears that your application still contains the default signing identifier.

Try replacing 'com.example' with your signing id in Xcode:

  open ios/Runner.xcworkspace

用xcode也能直接运行项目，排查了半天原来是手机重新插拔一下就ok了， 哎怪自己菜
