flutter - 向 ClipPath 添加背景颜色不起作用

Question

如何为自定义 ClipPath 添加背景颜色？

尝试了以下但它不工作

ClipPath(
    clipper: MyClipper(),
    child: Container(color: Colors.yellowAccent),
)

class MyClipper extends CustomClipper<Path> {
  @override
  Path getClip(Size size) {
    final Path path = Path();
    path.moveTo(0, 0);
    path.lineTo(size.width - 10, 0);
    path.lineTo(size.width, size.height / 2);
    path.lineTo(size.width - 10, size.height);
    path.lineTo(0, size.height);
    path.lineTo(0, 0);
    path.close();

    return path;
  }

  @override
  bool shouldReclip(MyClipper oldClipper) => false;
}
