toplinuxsir commented 1 year ago 
 final portReader = SerialPortReader("/dev/ttyACM0");

  try {
    port.config.baudRate = baudrate;
    port.config.bits = dataBits;
    port.config.parity = parity;
    port.config.stopBits = stopBits;
  } catch (e, s) {
    debugPrint("error : $e");

    debugPrint("stack trace: $s");
  }

error as below 

 SerialPortError: Invalid argument, errno = 22
flutter: stack trace: #0      Util.call (package:libserialport/src/util.dart:39:7)
