Also,

Is anybody facing the same issue? Any idea how to fix this?
Thank you
Solution
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.
