Flutter 自定义裁剪器半径

Question

我正在尝试通过 FLutter 中的自定义剪辑器制作自定义剪辑器，但我不知道如何在我的形状中添加一些圆角

左侧为所需结果的屏幕截图，右侧为我的结果:

这是我的剪辑代码

class SideArrowClip extends CustomClipper<Path> {
  @override
  Path getClip(Size size) {
    final Path path = Path();
    final double startMargin = size.width / 14;
    final double s1 = size.height * 0.4;
    final double s2 = size.height * 0.6;
    print('S1:$s1 SH:${size.height / 2} S2:$s2');
    path.lineTo(startMargin, 0);
    path.lineTo(startMargin, s1);
    path.lineTo(0, size.height / 2);
    path.lineTo(startMargin, s2);
    path.lineTo(startMargin, size.height);
    path.lineTo(size.width, size.height);
    path.lineTo(size.width, 0);
    path.close();
    return path;
  }

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

我使用 addRRect(RRect.fromRectAndRadius 来制作圆角矩形

import 'package:flutter/material.dart';

    class SideArrowClipper extends CustomClipper<Path> {
      @override
      Path getClip(Size size) {
        final double width = size.width;
        final double height = size.height;
        final double startMargin = width / 14;

        final double s1 = height * 0.3;
        final double s2 = height * 0.7;
        final Path path = Path()
          ..addRRect(RRect.fromRectAndRadius(
              Rect.fromLTWH(startMargin, 0, width-startMargin, height),
              const Radius.circular(5)))
          ..lineTo(startMargin, s1)
          ..lineTo(0, size.height / 2)
          ..lineTo(startMargin, s2)
          ..close();
        return path;
      }

      @override
      bool shouldReclip(CustomClipper<Path> oldClipper) {
        return oldClipper != this;
      }
    }
