根据给定的文字可以获得其宽度吗，未进行渲染前，如何获得文本的宽度？

@Entry  
@Component  
struct JSONTest {  
  @State cWidth: number = 200;  
  @State cHeight: number = 200;  
  build() {  
    Column() {  
      Column() {  
        Row() {  
          Text('isidjaslkjadskjdalksdjkajdksjdakd')  
            .id('111')  
        }  
        Button('show')  
          .type(ButtonType.Capsule)  
          .onClick(() => {  
            let jsonstr: string = getInspectorByKey('111')  
            console.log(jsonstr)  
            let obj = JSON.parse(jsonstr) as massage  
            console.log("data:" + obj.$attrs.size.height)  
  
            console.log("当前高度：" + this.cHeight + "当前高度：" + this.cHeight)  
          })  
      }  
      .backgroundColor(Color.Blue)  
  
      .width(this.cWidth)  
      .height(this.cHeight)  
  
    }  
    .width('100%')  
    .height('100%')  
  }  
}  
  
class massage{  
  $attrs : InnerMassage  
  
  constructor(inner : InnerMassage) {  
    this.$attrs = inner  
  }  
  
}  
  
class InnerMassage{  
  size : SizeMassage  
  
  constructor(size : SizeMassage) {  
    this.size = size  
  }  
}  
  
class SizeMassage{  
  height: string  
  width: string  
  
  constructor(height : string, width :string ) {  
    this.height = height  
    this.width = width  
  }  
}
