[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](https://hashnode.com/posts/flutter-bloc-v8-how-to-fetch-data-from-an-api-2022-guide/61d7d5078d56921d07b8ff95/comment/631f76c46c86d75accc7eb7d)
