1.graphic.stopFlicker()这个矢量数据在不知道id的情况下，怎么能够全部关闭或者批量关闭呢？

})
map.addLayer(graphicLayer)
// 在layer上绑定监听事件
graphicLayer.on(mars3d.EventType.click, function (event) {
console.log("监听layer，单击了矢量对象", event)
})
// 加一些演示数据
addDemoGraphic1(graphicLayer)

addDemoGraphic3(graphicLayer)
//在此处怎么批量关闭三个闪烁

return
}
const parent = graphic.parent // 右击是编辑点时
graphicLayer.removeGraphic(graphic)
if (parent) {
graphicLayer.removeGraphic(parent)

}
}
])
}
解决方案：
graphicLayer.eachGraphic((graphic) => {
if (graphic.stopFlicker) {
graphic.stopFlicker()
}
})
