HarmonyOS BindSheet再弹出一个Sheet

bindsheet支持叠加使用，具体用法请参考以下示例：

@Entry
@Component
struct BindSheetDemo {
  // 半模态转场显示隐藏控制
  @State isShowSheet: boolean = false;
  @State isShowDetailSheet: boolean = false;
  private menuList: string[] = ['直播间', '相关内容', '更多'];
  private detailList: string[] = ['直播间111111', '相关内容22222222', '更多334455665'];
  // 通过@Builder构建半模态展示界面
  @Builder
  mySheet() {
    Column() {
      Flex({ direction: FlexDirection.Row, wrap: FlexWrap.Wrap }) {
        ForEach(this.menuList, (item: string) => {
          Text(item)
            .fontSize(16)
            .fontColor(0x333333)
            .backgroundColor(0xf1f1f1)
            .borderRadius(8)
            .margin(10)
            .padding(10)
            .onClick(() => {
              this.isShowDetailSheet = !this.isShowDetailSheet;

            })
        })
      }
      .bindSheet(this.isShowDetailSheet, this.myDetailSheet(), {
        // height: 550,
        dragBar: true,
        onDisappear: () => {
          this.isShowDetailSheet = !this.isShowDetailSheet;
        }
      })
      .padding({ top: 18 })
    }
    .width('100%')
    .height('100%')
    .backgroundColor(Color.White)

  }
