Bloc: How do I replace BlocSupervisor().delegate when upgrading to 6.0.5?

[MilesAdamson]

Hi. I was previously on a very old version of flutter bloc, 3.0.1. I am trying to upgrade to 6.0.5, and have fixed everything except for this line:

BlocSupervisor.delegate = BlocTransitionListener(userLoggingInfo: sentryLogging);

Both BlocSupervisor and BlocSupervisor() are now undefined.

I can't find the new method of listening to all my bloc transitions. Please help, thank you

Thanks for this quick fix!
The migration guide should make this clear.
I got stuck try to set an observer on MyAppBloc (instead of the parent Bloc class!) :(

@ajaygautam this should be covered in the migration guide. Let me know if it was unclear/confusing and if there's anything you'd like to add or adjust 👍

@felangel thanks for the response.
My apologies. I didn't read correctly. All set now. Thanks
