HarmonyOS 鸿蒙Next Tabs选项卡组件有懒加载吗

目前tabs没有懒加载能力，可以看以下示例是否可以满足你的需求：

[@Entry](/user/Entry)
[@Component](/user/Component)
struct Index3 {
 [@State](/user/State) currentIndex: number = 0
 [@State](/user/State) tabContentArr: boolean[] = [true, false, false, false]
 tabContents: string[] = ["首页", "推荐", "发现", "我的"]

 build() {
   Row() {
     Column() {
       Tabs({ barPosition: BarPosition.End }) {
         ForEach(this.tabContents, (item: string, index) => {
           TabContent() {
             if (this.currentIndex === index || this.tabContentArr[index]) {
               TabChild({ index: this.currentIndex })
             }
           }.tabBar(item)
         })
       }
       .onChange((index) => {
         this.currentIndex = index
         this.tabContentArr[index] = true
       })
     }
     .width('100%')
   }
   .height('100%')
 }
}


[@Component](/user/Component)
export struct TabChild {
 [@Prop](/user/Prop) index: number = 0;
 build() {
   Column() {
     Text(this.index + '')
   }
 }
}
