+/// A debouncer is a utility class that allows you to debounce a function call.
+/// It is useful to prevent a function from being called too frequently.
+/// For example, if you have a function that is called when the user types in a search box,
+/// you can use a debouncer to prevent the function from being called too frequently.
+/// This is useful to prevent the server from being overwhelmed by too many requests.
+///
+/// Example:
+/// ```dart
+/// class SearchCubit extends Cubit<SearchState> {
+///   SearchCubit() : super(const SearchState());
+///
+///   late final Debouncer _debouncer = Debouncer();
+///
+///   void debouncedSearch(String searchQuery) {
+///     _debouncer.run(() => emit(state.copyWith(searchQuery: searchQuery.trim())));
+///   }
+///
+///   @override
+///   Future<void> close() {
+///     _debouncer.dispose();
+///     return super.close();
+///   }
+// }
+/// ```
