i want to bend the right hand side on a container

import 'package:flutter/material.dart';

class DiagonalClipper extends CustomClipper<Path> {
  @override
  Path getClip(Size size) {
    var path = Path();
    path.lineTo(0, 20); // Move 20 down from the top-left corner
    path.quadraticBezierTo(size.width * 0.5, 0, size.width, 0); // Curve to the top-right corner
    path.lineTo(size.width, size.height); // Right edge
    path.lineTo(0, size.height); // Bottom edge
    path.close(); // Close the path
    return path;
  }

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