How to draw path with multiple curves in flutter

Question

I am trying to draw path with multiple curves as shown in picture 1 But the curve getting drawn has breaks in between as shown in second picture Below is the code I am using

 Path drawPath(Constant c) {
   
    Path path = Path();
    //width,height
    path.moveTo(c.width! / 2, 0);
    path.quadraticBezierTo(c.width! / 4, c.height! * 0.10, c.width! / 4 + 100,
        c.height! * 0.10 + 100);
    path.relativeQuadraticBezierTo(c.width! / 4 + 100 + 50,
        c.height! * 0.10 + 100, c.width! - 300, c.height! / 4 * 2);
    return path;
  }

How can I make the curve joint smooth? What will be the right approach?
