在列表中使用子项的文件树，如何保持文件树的形状？

Question

List(
    [root],
    children: \.children)
) { item in
    
}

结构同上

我想向用户显示文件，因为它们是通过在文件树中搜索自动打开的。有办法吗？

        let item4 = Item(id: 4, name: "child 4", children: [item1, item2, item3])
        let item5 = Item(id: 5, name: "child 5", children: nil)
        let item6 = Item(id: 6, name: "child 6", children: nil)
        let root = Item(id: 7, name: "Parent", children: [item4, item5, item6])
        items = [root]
    }
}

struct Item: Identifiable {
    var id: Int
    var name: String
    var children: [Item]?
}
