CustomPainter and CustomClipper produce different outputs for same path - flutter

Question

I'm using path drawing. I must scale that path. I'm using bounds for scale but It doesn't work same for clipper and painter. I need same output.
Here is codes.
class PaintSvg extends CustomPainter{
PaintSvg(this.pathStr);
String pathStr;
#override
void paint(Canvas canvas, Size size) {
Paint paint = Paint();
paint.style = PaintingStyle.fill;
paint.color = Colors.red;
Path path = Path();
path = parseSvgPathData(pathStr);
Rect pathBounds = path.getBounds();
Matrix4 matrix4 = Matrix4.identity();
matrix4.scale(size.width/pathBounds.width, size.height/pathBounds.height);
path = path.shift(Offset(0,0));
path = path.transform(matrix4.storage);
canvas.drawShadow(path, Colors.green, 2, true);
//canvas.rotate(-math.pi/1.18);
canvas.drawPath(path, paint);
}
#override
bool shouldRepaint(CustomPainter oldDelegate) {
return true;
}
}
class ClipSvg extends CustomClipper<Path>{
String pathStr;
ClipSvg(this.pathStr);
#override
Path getClip(Size size) {
Path path = Path();
path = parseSvgPathData(pathStr);
Rect pathBounds = path.getBounds();
Matrix4 matrix4 = Matrix4.identity();
matrix4.scale(size.width/pathBounds.width, size.height/pathBounds.height);
path = path.transform(matrix4.storage);
path = path.shift(Offset(0,0));
return path;
}
#override
bool shouldReclip(ClipSvg oldClipper) => true;
}
Here is output.
ScreenShot of output
Brown one is clipper red one that behind the brown is painter. Two of them uses same svg data string.
