BlocxCollectionWidget<T extends BaseEntity, P> class
abstract
Base building block for list rows/cards that integrate with a ListBloc.
Requirements:
- An ancestor must provide
ListBloc<T, P>viaBlocProvider. - Subclasses implement buildContent to render the item.
Provides convenience methods to dispatch common list events (remove / select / deselect / highlight / clear highlight). Each method checks that the bloc supports the required capability mixin before dispatching; otherwise it throws a descriptive error.
