Could we allow to generate some types as private types to be consumed by the bloc itself only?

I would like to keep some of the types generated by the super enum being private and not to expose some bloc events to the outside rather keeping them private to the package.

Should be pretty simple to generate those types with an understood like _SomeTyperGenerated. Well seems like _SomeTyperGenerated is only private in the own file. Wondering what else I could do.
