Hi there,

basically the error occurred after updated to the newest flutter version 3.10.0.

I've tried a lot of stuff and as well as multiple options provided in this post.

The app is running on android emulator but not on Ios emulator. I am clueless what to do, so if you have any ideas, please feel free to comment below.
