The bloc_presentation package enables clean handling of one-time side effects—such as navigation, showing snackbars, or displaying dialogs—from Bloc or Cubit without cluttering the state. It separates presentation logic from state management by allowing events to trigger side effects directly, improving code clarity and testability. Designed for use with Flutter's Bloc/Cubit patterns, it ensures that UI-side actions are dispatched cleanly and efficiently across platforms.
