HarmonyOS @Builde修饰器内, 如何监听到isNormalMode的数据变化

调用@Builder装饰的函数，上述写法是按值传递参数。当传递的参数为状态变量时，状态变量的改变不会引起@Builder方法内的UI刷新。所以当使用状态变量的时候，推荐使用按引用传递。参考地址：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/arkts-builder-V5

参考以下代码：

class ImageParams {
  imageUrl: string | Resource = ''
  onImageClick: () => void = () => {
  }
}

@Entry
@Component
struct Index {
  @State isNormalMode: boolean = true;
  @State imgUrl: string | Resource = $r('app.media.img1')

  @Builder
  showImageNew(params: ImageParams) {

    Image(params.imageUrl)
      .fitOriginalSize(true)
      .objectFit(ImageFit.Auto)
      .width(200)
      .onClick(() => {
        console.log("obclick")
        params.onImageClick();
      })
  }

  @Builder
  showImage(source: string | Resource, onImageClick: () => void = () => {
  }) {
    Image(source)
      .fitOriginalSize(true)
      .objectFit(ImageFit.Auto)
      .width(200)
      .onClick(() => {
        console.log("obclick")
        onImageClick();
      })
  }

  build() {
    Stack({ alignContent: Alignment.TopStart }) {
      Flex({ direction: FlexDirection.Column }) {

        Column() {

          Text("状态：" + this.isNormalMode)
          Text(" imgUrl：" + JSON.stringify(this.imgUrl))

          this.showImage(this.imgUrl, () => {
            console.log("setImageobclick")
            this.isNormalMode = !this.isNormalMode;
            this.imgUrl = this.isNormalMode ? $r('app.media.img1') : $r('app.media.img2')
          })

          Button("changeType(只改状态，图没换)").onClick(() => {
            this.isNormalMode = !this.isNormalMode
          })

          //=================用下面这种的写法==========================
          this.showImageNew(
            {
              imageUrl: this.imgUrl,
              onImageClick: () => {
                this.isNormalMode = !this.isNormalMode;
                this.imgUrl = this.isNormalMode ? $r('app.media.img1') : $r('app.media.img2')
              }
            }
          )
          if (this.isNormalMode) {
            this.showImageNew(
              {
                imageUrl: $r("app.media.img1"),
                onImageClick: () => {
                  this.isNormalMode = !this.isNormalMode;
                  this.imgUrl = this.isNormalMode ? $r('app.media.img1') : $r('app.media.img2')
                }
              }
            )
          } else {
            this.showImageNew(
              {
                imageUrl: $r("app.media.img2"),
                onImageClick: () => {
                  this.isNormalMode = !this.isNormalMode;
                  this.imgUrl = this.isNormalMode ? $r('app.media.img1') : $r('app.media.img2')
                }
              }
            )
          }

        }
        .width("100%")
        .height("100%")
      }
    }
    .width("100%")
    .height("100%")
