flutter

1、方法的参数里边有方法

SceneHorizontalItemWidget(     sceneInfo,     sceneInfo.shotInfos![index],     index,     count, callback: (bool isHover) {     _isHover.value = isHover;   }) 

late final int sceneIndex; late final SceneInfo sceneInfo; late final ShotInfo shotInfo; late final int count; //水平列表的总数量 final Function _callback;  SceneHorizontalItemWidget(     this.sceneInfo, this.shotInfo, this.sceneIndex, this.count,     {super.key, required Null Function(bool isHover) callback})     : _callback = callback;

2、
