How can I use clippath to customise a container as shown in the image below?

Question

How can i do this in flutter, need help

I try this one but it did'nt work, it make only two arcs but i need four, if some one can help me to make this design.How can I make the above design, I tried but without success, I need help to make it in flutter with CustomClippath or CustomPaint widgets, Understanding how it works also escapes me a little, as does positioning a voluntary point on any side of my container and making a deformation there.

class CustomlipperTest extends CustomClipper<Path> {
  CustomlipperTest({this.radius = 38});
  final double radius;
  @override
