如何为CustomClipper创建的小部件制作合适的边框和阴影

import 'package:flutter/material.dart';

class CustomWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ClipPath(
      clipper: CustomClipperClass(),
      child: Container(
        // 添加边框和阴影
        decoration: BoxDecoration(
          border: Border.all(color: Colors.black, width: 2.0),
          boxShadow: [
            BoxShadow(
              color: Colors.grey.withOpacity(0.5),
              spreadRadius: 2,
              blurRadius: 5,
              offset: Offset(0, 3), // 阴影位置偏移量
            ),
          ],
        ),
        child: // 添加其他内容
      ),
    );
  }
}

class CustomClipperClass extends CustomClipper<Path> {
  @override
  Path getClip(Size size) {
    // 定义裁剪路径的逻辑
    Path path = Path();
    // 添加路径的绘制逻辑
    return path;
  }

  @override
  bool shouldReclip(CustomClipper<Path> oldClipper) {
    return false;
  }
}
