HarmonyOS鸿蒙Next中是否有同学用过material-dialogs三方库？能否提供一个demo

看看行不行

```typescript
import { ClickCallback, DialogAttributeModel, MaterialDialog, SingleChoiceListener } from '[@ohos](/user/ohos)/material-dialogs';

[@Entry](/user/Entry)
[@Component](/user/Component)
struct Index {
  [@State](/user/State) message: string = 'Hello World';
  model: MaterialDialog.Model = new MaterialDialog.Model();
  dialogAttribute = new DialogAttributeModel()
  [@State](/user/State) items: string[] = ['男', '女']
  [@State](/user/State) listenser: SingleChoiceListener1 = new SingleChoiceListener1()

  existDialog() {
    this.dialogController.close()
  }

  dialogController: CustomDialogController = new CustomDialogController({
    builder: MaterialDialog({
      model: this.model, dialogAttribute: this.dialogAttribute
    }),
    cancel: this.existDialog,
    autoCancel: true,
    alignment: DialogAlignment.Center,
    customStyle: true
  })

  build() {
    Row() {
      Column() {
        Text(this.listenser.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            //1. 弹出dialog
            this.model.reset()
            this.model.listItemsSingleChoice(this.items, 2, true, null, -1, -1, this.listenser)
            this.model.positiveButton('确定', Callback('', 0))
            this.model.negativeButton('取消', Callback('', 1))
            this.model.setStacked(false)
            this.dialogController.open()
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}

class SingleChoiceListener1 implements SingleChoiceListener {
  [@Track](/user/Track) message: string | Resource | undefined;
  onSelected(value: string, index: number) {
    //2. 获取到选择的性别（value = 男/女）
    //3. 需要把value值传给message属性，然后刷新界面，显示选择的性别
    this.message = value;
  }
}

function Callback(value1: string, type: number): ClickCallback {
  let back: ClickCallback1 = new ClickCallback1(value1, type)
  return back
}

class ClickCallback1 implements ClickCallback {
  value1: string = ''
  type: number = 0

  onClick(value?: string) {
    if (this.type === 0) {
      console.info(this.value1)
    } else if (this.type === 1) {
      console.info('ClickCallback when the confirm button is clicked')
    }
  }

  constructor(value: string, type: number) {
    this.value1 = value
    this.type = type
  }
}
