Flutter报错：A borderRadius can only be given for uniform borde

我爱模板网在做Flutter项目时，需要给Container设置底边框以及四个圆角，于是代码如下：

Container(
  width: double.infinity,
  height: ScreenUtil().setHeight(192.0),
  decoration: BoxDecoration(
    color: Colors.white,
    border: Border(
        bottom: BorderSide(width:.5, color: Colors.red)
    ),
    borderRadius: BorderRadius.only(
      topLeft: Radius.circular(10.0),
      topRight: Radius.circular(10.0),
    )
  ),
),

此时运行页面空白，还会报下面的错：

A borderRadius can only be given for a uniform Border.


从字面意思来看，是因为边界和borderRadius不统一，就是只有底边框，却设置了左上和右上的圆角，解决办法：
    1、将边框去了，用margin或再写个Container作为边框
    2、将圆角去了，用ClipRRect等方法实现圆角
    3、将四条边都加上，四条边必须边框粗细，颜色一致，否则还是会报上面的错：
        下面写法仍会报错：

border: Border(
    bottom: BorderSide(width:.5, color: Colors.red),
    left: BorderSide(width:.5, color: Colors.white),
    right: BorderSide(width:.5, color: Colors.white),
    top: BorderSide(width:.5, color: Colors.white)
),

        下面写法不会报错：

border: Border(
    bottom: BorderSide(width:.5, color: Colors.red),
    left: BorderSide(width:.5, color: Colors.red),
    right: BorderSide(width:.5, color: Colors.red),
    top: BorderSide(width:.5, color: Colors.red)
),

        或：

border: Border.all(width: 1, color: Colors.red)
