如何在<v-treeview> Vuetify中添加新节点

我目前正在使用Vuetify制作树状视图。树形视图使用以下结构：

      items: [
    {
      id: 1,
      name: 'Applications :',
      children: [
        { id: 2, name: 'Calendar : app' },
        { id: 3, name: 'Chrome : app' },
        { id: 4, name: 'Webstorm : app' }
      ]
    },
    {
      id: 5,
      name: 'Documents :',
      children: [
        {
          id: 6,
          name: 'vuetify :',
          children: [
            {
              id: 7,
              name: 'src :',
              children: [
                { id: 8, name: 'index : ts' },
                { id: 9, name: 'bootstrap : ts' }
              ]
            }
          ]
        },
        {
          id: 10,
          name: 'material2 :',
          children: [
            {
              id: 11,
              name: 'src :',
              children: [
                { id: 12, name: 'v-btn : ts' },
                { id: 13, name: 'v-card : ts' },
                { id: 14, name: 'v-window : ts' }
              ]
            }
          ]
        }
      ]
    },
    {
      id: 15,
      name: 'Downloads :',
      children: [
        { id: 16, name: 'October : pdf' },
        { id: 17, name: 'November : pdf' },
        { id: 18, name: 'Tutorial : html' }
      ]
    },
    {
      id: 19,
      name: 'Videos :',
      children: [
        {
          id: 20,
          name: 'Tutorials :',
          children: [
            { id: 21, name: 'Basic layouts : mp4' },
            { id: 22, name: 'Advanced techniques : mp4' },
            { id: 23, name: 'All about app : dir' }
          ]
        },
        { id: 24, name: 'Intro : mov' },
        { id: 25, name: 'Conference introduction : avi' }
      ]
    }
  ]
})

它看起来像这样：

我的问题是在此结构中添加一个新节点，例如，如果要在应用程序下添加一个子代，则代码可能如下所示：

this.items[0].children.push(newObject)

还是如果我想在src下添加？那么它可能看起来像这样：

this.items[1].children[0].children.push(newObject)

如果我想更深入一点，它可能看起来像这样：

this.items[0].children[0].children[0].children[0].children[0].children.push(newObject)

As you can see, the way I add a node varies and the code changes depending on the location and depth of where I want to add the node. That means there is no single code that will cater for all the locations. Also I can add and nest as many node as I can. example is google drive How should I go about this? I've run out of ideas and is looking for any suggestions that might help.
