自定义组件间如何实现从底部滑入滑出的效果

@Entry 
@Component 
struct ComponentTransition { 
  @State flag: boolean = true; 
 
  build() { 
    Stack({ alignContent: Alignment.Bottom }) { 
        if (this.flag) { 
          ComponentChild1({ flag: $flag }) 
            .transition({ type: TransitionType.Insert,translate: { x: 0, y: 200 } }) 
        } 
        if (!this.flag) { 
          ComponentChild2({ flag: $flag }) 
            .transition({ type: TransitionType.Insert, translate: { x: 0, y: 200 } }) 
        } 
    }.height('100%').width('100%') 
  } 
} 
 
@Component 
struct ComponentChild1 { 
  @Link flag: boolean 
 
  build() { 
    Column() { 
      Image($r('app.media.ic_banner01'))//resources\base\media路径 
        .width('100%') 
        .height(200) 
        .onClick(() => { 
          animateTo({ duration: 1000 }, () => { 
            this.flag = !this.flag; 
          }) 
        }) 
    } 
  } 
} 
 
@Component 
struct ComponentChild2 { 
  @Link flag: boolean

        .width('100%') 
        .height(200)
