AlertDialog.show的问题：HarmonyOS 鸿蒙Next中Property ‘show’ does not exist on type ‘typeof AlertDialog’

帮我看一看这是什么问题哦，天啊！show参数报错：Property ‘show’ does not exist on type ‘typeof AlertDialog’，以前用的好好的

import { AlertDialog,UIContext, PageInfo } from '@kit.ArkUI';
@Component
export  struct  TabDreamnoteComponent {
  @State titleValue: string = ''
  @State detailValue: string = ''
  txtController: TextInputController = new TextInputController()
  txtAreaController: TextAreaController = new TextAreaController()

  build() {

    Row() {
      Stack() {
        Column() {
          TextInput({ text: this.titleValue, placeholder: '录入主题，也可以是日期', controller: this.txtController })
            .margin({ top: 20 })

          TextArea({ text: this.detailValue, placeholder: '录入详细 ', controller: this.txtAreaController })
            .height(200)
            .margin(20)
            .onClick(() => {
              AlertDialog.show({
                title: '提示',
                message: '添加库存成功！'
              })

            }).backgroundColor(0x317aff)

        }.margin({ bottom: 300 })
      }.align(Alignment.Bottom)
      .width('100%').height('100%')
    }
    .backgroundImageSize({ width: '100%', height: '100%' })
    .height('100%')
  }
