ScrollList({Key? key, bool reverse = false, bool shrinkWrap = false, bool noScrollBehavior = false, bool? primary, Axis scrollDirection = Axis.vertical, Clip clipBehavior = Clip.hardEdge, DragStartBehavior dragStartBehavior = DragStartBehavior.start, String? restorationId, double? cacheExtent, ScrollPhysics? physics, EdgeInsetsGeometry? padding, RefreshConfig? refreshConfig, ScrollController? controller, required List<Widget> sliver, Widget? header, Widget? footer})
滑动类型设置 physics AlwaysScrollableScrollPhysics() 总是可以滑动 NeverScrollableScrollPhysics() 禁止滚动 BouncingScrollPhysics() 内容超过一屏 有回弹效果 ClampingScrollPhysics() 包裹内容 不会有回弹
