    (index) => ReorderableStaggeredScrollViewGridItem(
      key: ValueKey(index.toString()),
      mainAxisCellCount: 1,
      crossAxisCellCount: Random().nextInt(2) + 1,
      widget: Card(
        child: Center(child: Text('Item $index')),

ReorderableStaggeredScrollView.list(
  ...
)

Custom

You can integrate the ReorderableStaggeredScrollView package with your custom list or grid widget by wrapping your custom list or grid widget with the necessary components.

DragNotification(
  child: ListView(
    scrollDirection: Axis.vertical,
    children: [
      DragContainer(
        scrollDirection: Axis.vertical,
        isLongPressDraggable: true,
        buildItems: (List<Widget> children) {
          return YourCustomListViewWidget(
            // Your custom list or grid widget configuration
            children: children,
          );
        },
        dataList: yourList, // Your List of ReorderableStaggeredScrollViewListItem or ReorderableStaggeredScrollViewGridItem
        items: (ReorderableStaggeredScrollViewListItem element, DraggableWidget draggableWidget) {
          // Map each item in your dataList into a draggable widget
          return Container(
            key: ValueKey(element.key.toString()),
            child: draggableWidget(element.widget),
          );
        }
      ),
    ],
  ),
);

Replace the comments with your actual widget configuration and data. This setup will allow you to use the ReorderableStaggeredScrollView package with your custom widget.
