HarmonyOS 鸿蒙Next ArkUI 中 Text 组件如何实现字体的自动缩放

参考Demo：

[@Entry](/user/Entry)
[@Component](/user/Component)
struct Index {
  [@State](/user/State) texture: string = "Hello World Hello World"
  change: boolean = false;
  build() {
    Column() {
      Text(this.texture)
        .fontColor(Color.White)
        .minFontSize('1')
        .maxFontSize('40')
        .maxLines(1)
        .backgroundColor(Color.Brown)
        .height('40')
      .onClick(()=>{
        if (this.change) {
          this.change = false;
          this.texture = 'Hello World Hello World'
        } else {
          this.change = true;
          this.texture = 'Hello World Hello World Hello World Hello World Hello World Hello World'
        }
      })
    }
    .backgroundColor(Color.Blue)
    .height('100%')
    .width('100%')
  }
}
