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、
