HarmonyOS Row组件怎么居中

参考示例如下：

import { webview } from '@kit.ArkWeb';
import { BusinessError } from '@kit.BasicServicesKit';

@Entry
@Component
struct WebComponent {
  controller: webview.WebviewController = new webview.WebviewController();

  build() {
    Column() {

      Flex({ direction: FlexDirection.Row, justifyContent: FlexAlign.SpaceBetween, alignItems: ItemAlign.Center }) {
        Image($r('app.media.app_icon')).width(55).padding({
          left: 12, right: 8
        })
        Text('xx').width(55).fontSize(20).fontColor(Color.Pink).textAlign(TextAlign.Center)
        Divider().width(55).backgroundColor('#00000000').visibility(Visibility.Hidden)
      }.width('100%')
      .height(50)
    }
    .width('100%')
    .height('100%')
    .backgroundColor(Color.Brown)
  }
}
