Implementation

void moveItem({
  required int fromListIndex,
  required int fromItemIndex,
  required int toListIndex,
  required int toItemIndex,
}) {
  if (fromListIndex >= 0 && fromListIndex < _lists.length &&
      fromItemIndex >= 0 && fromItemIndex < _lists[fromListIndex].length &&
      toListIndex >= 0 && toListIndex < _lists.length &&
      toItemIndex >= 0 && toItemIndex <= _lists[toListIndex].length) {

    final item = _lists[fromListIndex].removeAt(fromItemIndex);
    _lists[toListIndex].insert(toItemIndex, item);

    // Notify about the move
    if (fromListIndex == toListIndex) {
      _callbacks?.onItemReorder?.call(fromListIndex, fromItemIndex, toItemIndex);
    } else {
      _callbacks?.onItemMove?.call(fromListIndex, fromItemIndex, toListIndex, toItemIndex);
    }

    notifyListeners();
