HarmonyOS 如何在Row中设置子组件为右侧对齐？

@Entry  
@Component  
struct linshi {  
  build() {  
    Stack() {  
      Row() {  
        Text('子组件1')  
}.justifyContent(FlexAlign.Start).width('100%').height('100%')  
      Row() {  
        Text('子组件2')  
}.justifyContent(FlexAlign.Center).width('100%').height('100%')  
      Row() {  
        Text('子组件3')    }.justifyContent(FlexAlign.End).width('100%').height('100%')  
    }  
  }  
}
