Hey, Nice article ! I like it, BTW when I run the compiled app, I have an issue :(

. The following \_CastError was thrown building \_BodyBuilder: type 'Null' is not a subtype of type 'JokeBloc' in type cast

The relevant error-causing widget was Scaffold package:test\_bloc/…/home/home.dart:15 When the exception was thrown, this was the stack

Any idea what it can be ? Because I'm really interested to use this pattern for our future apps
