error after upgrading Flutter 3.0

Not directly but from your dependency package "visibility_detector-0.2.2", which has been fixed and upgraded to 0.3.3 recently.

I know this is not the best practice but it works for me until the next update.
I simply opened the auto animated package project folder located in : {{flutter_folder}}/.pub-cache/hosted/pub.dartlang.org/auto_animated-3.0.1/
and I updated the pubspec.yaml by changing the visibility_detector version:
to: visibility_detector: ^0.3.3
