  }

  final paddedTileSize = tileSize + padding;
  final srcPosition = Vector2(
    spriteData.$1 * paddedTileSize + padding / 2,
    spriteData.$2 * paddedTileSize + padding / 2,
  );

  final srcSize = Vector2(
    (spriteData.$3 ?? 1) * tileSize,
    (spriteData.$4 ?? 1) * tileSize,
  );

  return Sprite(
    image,
    srcPosition: srcPosition,
