Constructors

DragSortView(List<DragBean> data, {Key? key, double? width, double space = 5, EdgeInsets padding = EdgeInsets.zero, EdgeInsets margin = EdgeInsets.zero, required IndexedWidgetBuilder itemBuilder, required WidgetBuilder initBuilder, OnDragListener? onDragListener})
create DragSortView. It is recommended to use a thumbnail picture，because the original picture is too large, it may cause repeated loading and cause flashing. 建议使用略微缩图，因为原图太大可能会引起重复加载导致闪动.
