自定义弹窗如何嵌套使用

@CustomDialog 
struct MyDialog1 { 
  controller2: CustomDialogController 
  // 指向自己的CustomDialogController放在最后，否则会引起崩溃 
  controller1: CustomDialogController 
  title: string 
 
  build() { 
    Row() { 
      Column({ space: 10 }) { 
        Text(this.title) 
          .fontSize(25) 
          .fontColor(Color.Blue) 
        Button('点击打开弹窗2')
