Here is what I got after running the App (This is the app I am working everyday, it worked well yesterday, and today when I started again, I got these error. This error might happened after I updating Xcode):

I have searched on google trying to solve myself, but I can't find the right answer and sometimes I don't understand people's comments, I have tried "flutter --clean", "flutter upgrade", "sudo gem install cocoapods", " pod setup", and "flutter build ios", but nothing helps.

Please, is there anyone to help me? I don't understand why I got error, what is the problem and how to solve it. Thank you very much!

Hi @lutang123
Can you please provide your flutter run --verbose and your pubspec.yaml. If the logs are too long you can provide it as a .txt file.
Thank you

update:

It took me half a day trying to figure out what's going wrong, and only realized that I can just re-start my Macbook and the error goes away and my app runs again!

conclusion:

After updating Xcode, I should re-start computer to be able to use it.

Hi, thank you for your quick reply and changed to a better title. I later re-started my computer and it runs again, I didn't know it can be that easy...

@lutang123 Thanks!

I'm using MacBook Air M1. I also occurred the same issue and I solved it using the same way.
