Improve BlocDelegate Initialization

[felangel]

Is your feature request related to a problem? Please describe.
Setting a custom BlocDelegate is a bit confusing in its current state.
We need to do:

BlocSupervisor().delegate = MyBlocDelegate()

This makes it seem like we are creating a new instance of the BlocSupervisor when instead we are retrieving a reference to the singleton instance.

Describe the solution you'd like
It would be a bit more intuitive to initialize the delegate like:

BlocSupervisor.delegate = MyBlocDelegate();

Merged in #305 and will be included in bloc v0.14.0

I'm having trouble creating my own BlocDelegate, when overriding onTransition I get an error, did the annotation change? Thanks

@AlejandroC90 can you please share your BlocDelegate code as well as the error you’re getting? Thanks!

Sorry for late response, but I was just getting and error with the old BlocDelegate.
class SimpleBlocDelegate extends BlocDelegate {
@override
void onTransition(Transition transition) {
print(transition.toString());
}
}

Didnt know that I had to update it to:

class SimpleBlocDelegate extends BlocDelegate {
@override
void onTransition(Bloc bloc, Transition transition) {
super.onTransition(bloc, transition);
print(transition);
}
}

Thanks for the response
