there are a lot of packages in your project. which package do you want to run — Yunus Kocatas

At times flutter does this problem. It does not run on emulator. But, when you try to run on actual phone, it will work perfectly. — Ujjwal Raijada

Can it be simply a timeout? 25s is quite a lot of time, I can understand that the IDE would think that something has failed and give a generic error. — il_boga

Just try to switch channel to master and rerun. I believe it may be a flutter bug but this simple change fixed it for me. In my case even a new app via flutter create would not execute on iOS and would throw many such errors - now it runs on iPhone 13 perfectly.
