After many checks, I realized that this problem happened after version 10.4.5 and the problem started in version 11.0.0.

Version 10.4.5 has no problem!

Dear @mbfakourii,

Thanks for your input. It looks like an issue on windows. I tried to reproduce this on a Mac but so-far no luck. I'll keep it open for now.

Kind regards,

I'm also experiencing the same thing in Windows.

I use mac and use plugin version 11.3.1 and flutter version 3.22.2, I added version 11.3.1 to empty project and flutter run -d web-server --web-port 8080 --web-hostname xxx.xxx.xxx.xx If you build using this command, the above error occurs.

Version 10.4.5 has no problem!

Thank you, I'm experiencing this issue in Windows too, it prevents the App to load in the browser.
Version 10.4.5 worked!
