I'm currently using the Facebook Login package for Flutter for a Flutter app that I'm developing and I'm having problems with building it in iOs.
I've followed all the steps in the guide and works fine in Android but when I try to run it in iOs simulator I have this output
Launching lib/main.dart on iPhone X in debug mode...
Running pod install...
Starting Xcode build...
Xcode build done. 3.0s
Failed to build iOS app
Error output from Xcode build:

I did flutter clean and pod update in the ios folder but keeps crashing. I don't know what's happening and if it's more a package problem than mine.
Here's the output of my flutter doctor -v

I'd appreciate if someone could help me finding the cause of this issue because I'm pretty lost right now.
Thanks in advance!
