flutter - 如何从右上角而不是左上角启动CustomClipper(ClipPath)

Question

我的CustomClipper从左上角开始，但是，我希望它从右上角开始。
这是我的代码:
快船队:

class ProfileBarClipper extends CustomClipper<Path> {
  @override
  Path getClip(Size size) {
    var path = new Path();
    path.lineTo(0, size.height - 50);
    var controllPoint = Offset(50, size.height);
    var endPoint = Offset(size.width / 2, size.height);
    path.quadraticBezierTo(
        controllPoint.dx, controllPoint.dy, endPoint.dx, endPoint.dy);
    path.lineTo(size.width, size.height);
    path.lineTo(size.width, 0);

    return path;
  }

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

ProfileBarClipper()的用法:

ClipPath(
    clipper: ProfileBarClipper(),
    child: Container(
        color: Colors.white,
        height: 200,
    ),
)

使用moveTo。

像这样。

var path = new Path();
path.moveTo(size.width,0); // (size.width, 0) means top right

更新:检查一下...

class ProfileBarClipper extends CustomClipper<Path> {
  @override
  Path getClip(Size size) {
    var path = new Path();
    path.moveTo(size.width, 0);
    path.lineTo(size.width, size.height - 50);
    var controllPoint = Offset(size.width-50, size.height);
    var endPoint = Offset(size.width / 2, size.height);
    path.quadraticBezierTo(
        controllPoint.dx, controllPoint.dy, endPoint.dx, endPoint.dy);
    path.lineTo(0, size.height);
    path.lineTo(0, 0);

    return path;
  }

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

输出:
