I am building a Flutter application that needs to transmit data through a wired connection between two tablets (Samsung Galaxy Tab S7+). Both tablets will be running the same Flutter application. I can not use any form of wireless connection like WIFI or Bluetooth so I will need to use USB. The data will be something simple like a string. Both tablets should be able to send and receive messages at any time to the other tablet.
I have used the usb_serial package and I am able to see the connection when I plug the tablets together but I can't figure out how to receive messages. https://pub.dev/packages/usb_serial/example
I could also use a USB-C to Ethernet adapter on the tablet if that helps but again there can be no wireless networking.
Is there any way to pass the data between these devices using Flutter?
