HarmonyOS 鸿蒙Next中动态更新range的问题

可以使用DialogHelper.update刷新自定义弹窗，即可实现弹窗中数据的动态更新。

示例代码如下：

import { DialogAction, DialogHelper } from '@pura/harmony-dialog';
import { TextPickerOptions } from '@pura/harmony-dialog/src/main/ets/model/TextPickerOptions';

class AreaEntity {
  text: string;
  level: string;
  code: string;
  pcode: string;
  children: Array<AreaEntity>;

  constructor(text: string, level: string, code: string, pcode: string, children: Array<AreaEntity>) {
    this.text = text;
    this.level = level;
    this.code = code;
    this.pcode = pcode;
    this.children = children
  }
}

@Entry
@Component
struct TextPickerDialogExample {
  private dialogId: string = ''
  @State dateList: Array<AreaEntity> = [
    new AreaEntity('北京市', '0', '0', '0', [
      new AreaEntity('北京市', '0', '0', '0', [
        new AreaEntity('朝阳区', '0', '0', '0', []),
        new AreaEntity('金水区', '0', '0', '0', []),
        new AreaEntity('丰台区', '0', '0', '0', [])
      ])
    ]),
    new AreaEntity('河南省', '0', '0', '0', [
      new AreaEntity('开封市', '0', '0', '0', [
        new AreaEntity('尉氏县', '0', '0', '0', []),
        new AreaEntity('沐风县', '0', '0', '0', []),
        new AreaEntity('襄阳区', '0', '0', '0', [])
      ])
    ]),
  ]
  @State dateListInfo: Array<AreaEntity> = [
    new AreaEntity('江苏省', '0', '0', '0', [
      new AreaEntity('苏州市', '0', '0', '0', [
        new AreaEntity('江宁区', '0', '0', '0', []),
        new AreaEntity('绿水区', '0', '0', '0', []),
        new AreaEntity('天启区', '0', '0', '0', [])
      ])
    ]),
    new AreaEntity('天津市', '0', '0', '0', [
      new AreaEntity('开封市', '0', '0', '0', [
        new AreaEntity('尉氏县', '0', '0', '0', []), 
        new AreaEntity('沐风县', '0', '0', '0', []),
        new AreaEntity('襄阳区', '0', '0', '0', [])
      ])
    ]),
  ]

  build() {
    Row() {
      Column() {
        Text(this.dateList[0].text).fontSize(18)
        Button("showTextPickerDialog")
          .padding({ top: 10, bottom: 10 })
          .onClick(() => {
            this.dialogId = ''
            let op: TextPickerOptions = {
              title: "请选择",
              range: this.dateList,
              onChange: (value: string | string[], index: number | number[]) => {
                if (value.length >= 2) {
                  const newDate = [...this.dateList]
                  newDate[0] = this.dateListInfo[0]
                  this.dateList = newDate
                  op.range = this.dateList
                  DialogHelper.update(this.dialogId, op) // 刷新自定义弹窗
                }

              },
              onAction: (action: number, dialogId: string, value: string | string[]) => {
              }
            }
            this.dialogId = DialogHelper.showTextPickerDialog(op)
          })
      }.width('100%')
    }.height('100%')
  }
}
