d4_path library

Say you have some code that draws to a 2D canvas:

drawCircle(context, radius) {
  context.moveTo(radius, 0);
  context.arc(0, 0, radius, 0, 2 * pi);
}

The d4_path package lets you take this exact code and additionally render to SVG. It works by serializing CanvasPathMethods calls to SVG path data. For example:

final path = Path();
drawCircle(path, 40);
path.toString(); // "M40,0A40,40,0,1,1,-40,0A40,40,0,1,1,40,0"

Now code you write once can be used with both Canvas (for performance) and SVG (for convenience). For a practical example, see d4_shape.
