PdfIconHelper class

Helper class for converting Flutter icons to PDF-compatible image bytes.

The pdf package does not support IconData directly, so this helper converts icons (Material Icons, FontAwesome, etc.) to PNG bytes that can be rendered in PDFs.

Example usage:

final iconBytes = await PdfIconHelper.iconToBytes(
  Icons.shopping_cart,
  size: 48,
  color: Colors.blue,
);
