Is anybody facing the same issue? Any idea how to fix this?

Thank you


I was able to fix the issue. It seems to be a random issue that happens time to time when updating either the flutter version or iOS…

Here’s how I fixed the issue:

However, what worked for me was very simple as I am using vs code:

  • uninstalled the app
  • restarted the phone
  • open the app using Xcode
  • Product -> Clean Build Folder
  • Product -> Run

The app will launch correctly, then quit Xcode

After that, I run the app using vs code, and now it works as before.
