How do you draw more complex custom shapes using the Path class within a CustomPainter, rather than being limited to Flutter's simpler built in shapes like circles and rectangles?

The Path class lets you construct an arbitrarily complex custom shape by describing a sequence of individual drawing movements, such as moving to a specific starting point, drawing a straight line to another point, or drawing a smooth curved line using a quadratic or cubic bezier curve, and once a Path object has been fully constructed describing your desired shape's outline, you can pass it to the canvas's drawPath method to actually render that complete custom shape, which enables drawing complex custom graphics like a custom wave shape or an irregular polygon that would not be possible using Flutter's simpler built in shape drawing methods alone.

final path = Path()
  ..moveTo(0, 50)
  ..quadraticBezierTo(100, 0, 200, 50)
  ..lineTo(200, 100)
  ..close();
canvas.drawPath(path, paint);
