有没有分开监听同一个类中不同属性的方法？

class GreenButtonState { 
  width: number = 0; 
  height: number = 0; 
 
  constructor(width: number, height: number) { 
    this.width = width; 
    this.height = height; 
  } 
} 
 
@Component 
struct GreenButton { 
  @Link @Watch('onUpdated') greenButtonState: GreenButtonState; 
 
  onUpdated(name: String): void { 
    console.log('111:' + this.greenButtonState.width + ' ' + this.greenButtonState.height) 
    this.updateWidth(); 
    this.updateHeight() 
  } 
 
  updateWidth(): void { 
    let width = this.greenButtonState.width; 
    console.log('width:' + width) 
  } 
 
  updateHeight(): void { 
    let height = this.greenButtonState.height; 
    console.log('height:' + height) 
  } 
 
  build() { 
    Button('Green Button') 
      .width(this.greenButtonState.width) 
      .height(this.greenButtonState.height) 
      .backgroundColor('#00ff00') 
      .onClick(() => { 
        if (this.greenButtonState.width < 700) { 
          // 更新class的属性，变化可以被观察到同步回父组件 
          this.greenButtonState.width += 20; 
        } else { 
          // 更新class，变化可以被观察到同步回父组件 
          this.greenButtonState = new GreenButtonState(50, 100); 
        } 
      }) 
  } 
} 
 
 
@Component

  @Link yellowButtonState: number; 
 
  build() { 
    Button('Yellow Button') 
      .width(this.yellowButtonState) 
      .height(150.0)
