0.0.2

Jul 25, 2025

🗑️ Removed

• FormSubmissionState
• BaseBloc
• LoadingCubit

♻️ Changed

• Replaced ReportEitherExtensions with a new version ResultEitherExtensions on Either<L, R> to better conform to functional and reactive programming practices.

  • Added a return type Future<R?> to make the method more versatile and chainable.
  • Used nullability to clearly express the absence of a result.
  • Improved error and stack trace logging.
  • Provided consistent handling for empty list checks (successReport is List && successReport.isEmpty).

Notes

• The new ResultEitherExtensions.handleReport allows for better integration in async workflows and makes handling success/failure/empty-list states easier and safer.
• Deprecated the old ReportEitherExtensions usage in favor of this newer and cleaner implementation.

0.0.1
