HarmonyOS 怎么设置带圆角的渐变边框

设置带圆角的渐变边框可以采用渐变色linearGradient来实现，参考demo如下

@Entry
@Component
struct BorderDemo {
  build() {
    Column() {
        Row(){
          Text('This is gradient color.')
            .textAlign(TextAlign.Center)
            .width('96%')
            .height('80%')
            .borderRadius(30)
            .linearGradient({
              direction: GradientDirection.Left, // 渐变方向
              repeating: true, // 渐变颜色是否重复
              colors: [[0xDCDCDC, 0.0],  [0xFFFFFF, 1.0]] // 数组末尾元素占比小于1时满足重复着色效果
            })
        }
        .width('90%')
        .height(60)
        .borderRadius(30)
        .linearGradient({
          angle: 90,
          colors: [[0x87CEEB, 0.0], [0x2E8B57, 1.0]]
        })
        .opacity(0.6)
        .justifyContent(FlexAlign.Center)
    }
    .height('100%')
  }
}
