null safety enabled - long list of errors

great work with this riverpod phone auth example, thank you for that :)
There is a problem though. I am using latest version of Flutter SDK and this is my pubspec.yaml file:

Kind regards, Neon
I did not try the example with Flutter 3, for the needs of another project, I cannot upgrade to Flutter 3 at the moment. But with Flutter 2.10.5, the example compiles fine and launches on my device. Could you try to revert to Flutter 2.10 and try to compile? If it works, then this is probably an issue due to Flutter 3 requirements and I will upgrade as soon as I can 😌
Err, can't revert back on this machine :) But i will try to look at it and see if i can fix it. Otherwise i will wait for you to make it Flutter 3 ready :D
I'm trying to make progress with null safety of the example, help would be appreciated https://github.com/julienlebren/flutter_firebase_phone_auth_riverpod/pull/6
