I get this error all the time! Usually when trying to build my iOS app.

Things that normally fix it are:

cd ~/ios/

rm -rf Pods

rm Podfile.lock

cd .. to (to get back to main flutter dir) flutter clean

If that doesn't work you can also try these afterwards

cd /ios/

pod deintegrate

pod install

If issues persist after those and this happens when trying to build your iOS app sometimes its a good idea to back up your iOS folder delete it and then run flutter create this will generate a new iOS folder so you have a fresh runner and can make a fresh pod file.

If none of my solutions worked for you can also check out this SO thread because this issue pops up a lot.

What version of flutter are you using? – Amxela Apr 08 '21 at 18:37
Flutter 2.0.4 version – Chetan Khanna Apr 08 '21 at 19:05
@ChetanKhanna were you able to fix this issue? I am facing the same issue and I am using Flutter 2.0.4 as well. – Junaid Rehmat Apr 15 '21 at 06:18
@JunaidRehmat what I did was remove the packages that were causing these errors. – Chetan Khanna Apr 16 '21 at 17:33
@ChetanKhanna In my case it was Firebase Crashlytics and other required packages, so I updated them one by one and that fixed the issue. – Junaid Rehmat Apr 19 '21 at 07:05
seem to work for me. Turned out I didn't have pods install ... android dev trying to learn IOS. – SeanDp32 Jun 04 '21 at 02:13
