HarmonyOS 如何定义组件插槽

@Component  
export struct settingsTileBuilder {  
  @Prop icon:  PixelMap | ResourceStr | DrawableDescriptor;  
  @Prop title: string | ResourceStr  
  onTap: Function = ()=>{ }  // 由于@Prop不能传递Function类型数据，所以不使用@Prop修饰，直接传递，也可以  
  
  @Builder soltBuilder() {}  
  // 使用父组件@Builder装饰的方法初始化子组件@BuilderParam  
  @BuilderParam customBuilderParam: () => void = this.soltBuilder;  
  
  build() {  
    Row() {  
      Image(this.icon)  
        .width('17vp')  
        .height('17vp')  
      Text(this.title)  
        .fontColor(Color.Black)  
        .fontSize('16fp')  
        .margin({ left: '10vp' })  
      Blank()  
  
      this.customBuilderParam();  // 插槽使用  
  
      Image($r('app.media.foreground'))  
        .size({ width: '9vp', height: '9vp' })  
        .objectFit(ImageFit.Contain)  
        .fillColor(Color.Black)  
        .opacity(0.4)  
    }  
    .padding({ left: '30vp', right: '30vp', top: '25vp', bottom: '25vp' })  
    .width('100%')  
    .onClick(() => {  
      this.onTap();  
    })  
  }  
}  
  
//  调用settingsTileBuilder组件  
@Entry  
@Component  
struct Index {  
  @Builder componentBuilder() {  
    Text(`Parent builder`)  
  }  
  
  build() {  
    Row(){  
      Text('父组件')  
      settingsTileBuilder({  
        icon: $r('app.media.startIcon'),  
        title: '子组件',  
        onTap: ()=>{ console.info(`1111111`) },  
        customBuilderParam: this.componentBuilder  
      })  
    }  
  }  
}
