HarmonyOS ArkUI如何动态禁用组件？

@Entry  
@Component  
struct Index {  
  @State isOn: boolean = true;  
  build() {  
    Row() {  
      Toggle({  
        type: ToggleType.Switch,  
        isOn: true  
      })  
        .onChange((isOn: boolean) =>{  
          this.isOn = isOn;  
        })  
      TextInput()  
        .enabled(this.isOn)  
    }  
  }  
}
