请教下，如果小程序根据登录用户的类型不同，展示的底部tabBar菜单是不同的，那么设置底部菜单的操作应该是在哪一步设置比较合理呢？我是在自定义tabBar组件的attached钩子函数进行设置，会发现首次进入小程序，底部导航对应加载的时候，tabBar都会自动加载，导致的问题，就是底部菜单会出现闪动现象，个人感觉导致这个问题的原因是 tabBar所在页面首次加载都会触发tabBar组件的attached钩子函数，那么要避免这种闪动现象，设置底部菜单的时机是什么时候呢以及具体如何操作，请各位大佬给点儿指示

以下为tabBar组件模拟动态设置底部菜单代码片段

data: {
    selected: 0,
    color: "#7A7E83",
    selectedColor: "rgb(63, 201, 205)",
    list: [
      {
        pagePath: "/pages/index/index",
        key: 0,
        iconPath: "/assets/images/tab_home.png",
        selectedIconPath: "/assets/images/tab_home_pre.png",
        text: "首页"
      },
      {
        pagePath: "/pages/mine/mine",
        key: 2,
        iconPath: "/assets/images/tab_my.png",
        selectedIconPath: "/assets/images/tab_my_pre.png",
        text: "我的"
      }
    ]
  },
lifetimes: {
    attached () {
        
      if ([1, 2].includes(this.data.accountType) && this.data.list.length == 2) {
        // 管理员、子账号
        let list = this.data.list
        list.splice(1, 1, {
          pagePath: "/pages/adt/adminBack/adminBack",
          iconPath: "/assets/images/tab_bill.png",
          selectedIconPath: "/assets/images/tab_bill_pre.png",
          text: "账单",
          key: 1
        }, list[1])
        this.setData({
          list: list
        })
      } else if (this.data.accountType == 3) {
        setTimeout(() => {
          let showAccount = true
          
          if (showAccount && this.data.list.length == 2) {
            let list = this.data.list
            list.splice(1, 1, {
              pagePath: "/pages/adt/adminBack/adminBack",
              iconPath: "/assets/images/tab_bill.png",
              selectedIconPath: "/assets/images/tab_bill_pre.png",
              text: "账单",
              key: 1
            }, list[1])
            this.setData({
              list: list
            })
          }
