dart_serial_port is based on FFI + libserialport, which must be deployed with the app. Pure Dart packages don't have a way to build C libraries, but it is possible to make use of Flutter's build system to do that. You can replace the dart_serial_port dependency in your pubspec.yaml with flutter_serial_port to automatically build and deploy libserialport.dll:

flutter_serial_port:
  git: https://github.com/jpnurmi/flutter_serial_port

Hope this helps!

Notice that dart_serial_port's wrapper https://github.com/jpnurmi/flutter_serial_port is not the same as the old deprecated https://pub.dev/packages/flutter_serial_port package on pub.
