suggestion: Consider simplifying the nested conditional logic

The nested ternary operator makes the code harder to read. Consider using if/else statements or extracting this logic into a separate method for better maintainability.

.toList();
List<String> hexString = Converters.convertBitmapToLEDHex(badgeGrid, false);
if (widget.isSavedCard!) {
  fileHelper.updateBadgeText(widget.filename!,
