Xcode build error for Flutter with Firebase-auth plugin on beta 0.3.2 : incompatible block pointer

This concerns firebase-auth plugin for flutter. I have the same code running on two mac computers. I just did a fresh install on the latter, and get a build error on FirebaseAuthPlugin.m : Incompatible block pointer

/Users/sergebesnard/Development/flutter/.pub-cache/hosted/pub.dartlang.org/
firebase_auth-0.5.9/ios/Classes/FirebaseAuthPlugin.m:69:53:
Incompatible block pointer types sending 'void (^)(FIRUser *__strong, NSError *__strong)' to parameter of type 'FIRAuthDataResultCallback _Nullable' (aka 'void (^)(FIRAuthDataResult * _Nullable __strong, NSError * _Nullable __strong)')

On my laptop, the code builds smoothly, the only difference being the beta version, which is 0.3.1 and that the android toolchain is installed.

On the iMac (failing) :

the Podfile is the same :

I frankly would prefer not to test upgrading the flutter sdk on my working setup, I still need to work on that stuff...

I don't know if this is helpful, but during setup, I ran into a problem on the installation of flutter on XCODE, because XCODE was not fully setup when at the time. flutter doctor did ask me to install the package six, and had problem because of a conflict in python@2 versions, so I force uninstalled via brew python@2 and reinstalled it, then could install via `pip install six``

If this is the cause, I will have to reinstall XCODE & Flutter. Hopefully not the case.

Thanks Serge

update the repository of cocoapods.

pod repo update

Then deletes Podfile, Podfile.lock, Pos directory, .flutter-plugins, .packages, pubspec.lock
