Fatal error: Unexpectedly found nil while unwrapping an Optional value

[kiranigeektech]

Hi

I'm trying to use writeValue() function to write binary code and i'm using following code.

 var value = Uint8List.fromList(hex.decode(binaryCode.text));
 QuickBlue.writeValue(
  widget.deviceId, 'e5f5f000-c0ec-46ba-bd1f-b4c9f0da4208', 'e5f50001-c0ec-46ba-bd1f-b4c9f0da4208',
  value, BleOutputProperty.withResponse);

But i'm getting following error.

quick_blue_macos/QuickBlueMacosPlugin.swift:32: Fatal error: Unexpectedly found nil while unwrapping an Optional value

Can you please help me to sort out this issue.

Thank you in advance.
