Description

This pull request introduces a new method to the Bloc class in the bloc.dart file, allowing for conditional event addition.

Enhancements to Bloc class:

• packages/bloc/lib/src/bloc.dart: Added the addIf method to the Bloc class, which allows adding an event based on a given condition. This is useful for scenarios where events should only be added under specific conditions.

This functionality simplifies the process of adding events conditionally, reducing repetitive if statements outside of the Bloc and promoting cleaner, more maintainable code.

This is an example using addIf method:

BlocProvider<MyBloc>(
              create: (context) => MyBloc(
                myRepository: context.read<MyRepository>(),
              )..addIf(
                  condition: condition == true,
                  eventBuilder: () => AddEvent(),
                ),
              child: HomePage(),
            );

Example without addIf method:

if(condition == true) {
              return BlocProvider<MyBloc>(
              create: (context) => MyBloc(
                myRepository: context.read<MyRepository>(),
              )..add(AddEvent()),
              child: HomePage(),
            );
} else {
 return BlocProvider<MyBloc>(
              create: (context) => MyBloc(
                myRepository: context.read<MyRepository>(),
              ),
              child: HomePage(),
            );

}
