+/// A hook that creates a [Debouncer] with automatic disposal.
+///
+/// The debouncer will be created once and automatically disposed when the
+/// widget is unmounted.
+///
+/// Example:
+/// ```dart
+/// final debouncer = useDebouncer(const Duration(milliseconds: 300));
+///
+/// // Use the debouncer
+/// debouncer.eventOccured(() {
+///   // Your debounced action
+/// });
+/// ```
+Debouncer useDebouncer(Duration duration) {
+  final debouncer = useMemoized(() => Debouncer(duration));
+  useEffect(() => debouncer.dispose, [debouncer]);
+  return debouncer;
