Flutter npm flutter_bloc migration to 6.1.1

Question

I have a question if somoneone know how to make the migration to flutter_bloc 0.6, to 6.1, because I updated the version and now is all givin errors, if someone know how to do it or a bit explanation or some link to migration do it, will be great, thanks.

Some Errors:

The method 'dispatch' isn't defined for the type 'TabsBloc'.
The superclass 'Bloc<ThemeEvent, ThemeState>' doesn't have a zero argument constructor.
The named parameter 'builder' isn't defined.
The method 'dispose' isn't defined for the type 'ThemeBloc'.

I would suggest that you slowly upgrade your flutter_bloc version so that you can gradually fix its errors. Sample, 0.6.0 -> 0.7.0, if no errors, upgrade again. — rickimaru, Jan 29 '21 at 09:02
