@override
T? removeAtEmit(int index) {
  final currentState = state;
  if (currentState is! SmartPaginationLoaded<T>) return null;

  final updated = List<T>.from(currentState.allItems);

  if (index < 0 || index >= updated.length) return null;

  final removedItem = updated.removeAt(index);

  _onInsertionCallback?.call(updated);

  _refreshDataAge();
  emit(
    currentState.copyWith(
      allItems: updated,
      items: updated,
      lastUpdate: DateTime.now(),
      fetchedAt: _lastFetchTime,
      dataExpiredAt: _getDataExpiredAt(),
    ),
  );
  return removedItem;
