+/// A mixin that provides a stream of update events.
+///
+/// This mixin is used to notify listeners when an update occurs.
+/// It is used in the [RefreshStreamMixin] class.
+///
+/// Example:
+/// ```dart
+/// class MyRepository with RefreshNotifierMixin {
+///   void create() {
+///     // Execute create logic
+///     refreshListeners(RefreshType.create);
+///   }
+///
+///   void update() {
+///     // Execute update logic
+///     refreshListeners(RefreshType.update);
+///   }
+/// }
+/// ```
+///
+/// Then you can listen to the refresh stream like this:
+/// ```dart
+/// myRepository.listen((event) {
+///   switch (event) {
+///     case RefreshType.create:
+///       // Execute create logic
+///       break;
+///     case RefreshType.update:
+///       // Execute update logic
+///       break;
+///   }
+/// });
+/// ```

+    return _refreshStream.stream.listen(events);
+  }
+
+  /// Closes the refresh stream.
+  Future<void> close() async {
+    await _refreshStream.close();
+  }
+}
+
+/// The type of refresh event.
+enum RefreshType {
+  /// The [RefreshType.create] event should be used when a new object is created.

+  /// The [RefreshType.update] event should be used when an object is updated.
+  update,
+
+  /// The [RefreshType.delete] event should be used when an object is deleted.
+  delete,
+
+  /// The [RefreshType.custom] event should be used when a custom event occurs,
+  /// if the refresh should trigger different logic than a normal create/update/delete event.
+  /// This way you can separate behaviour in the place where you are listening to the events
