A DGT-Chessboard Driver written in pure Dart

dgtdriver #

The dgtdriver flutter package allows you to quickly get you dgt-board connected to your Android application.


Getting Started with dgtdriver + usb_serial #

Add dependencies to pubspec.yaml

	dgtdriver: ^0.0.1
	usb_serial: ^0.2.4

include the package

import 'package:dgtdriver/dgtdriver.dart';
import 'package:usb_serial/usb_serial.dart';

add compileOptions to android\app\build.gradle

android {
    compileOptions {
        sourceCompatibility 1.8
        targetCompatibility 1.8

you can do optional more steps to allow usb related features, for that please take a look at the package we depend on: usb_serial.

Connect to a connected board and listen to its events:

List<UsbDevice> devices = await UsbSerial.listDevices();
    List<UsbDevice> dgtDevices = devices.where((d) => d.vid == 1115).toList();
    UsbPort usbDevice = await dgtDevices[0].create();
    await usbDevice.open();

    DGTCommunicationClient client = DGTCommunicationClient(usbDevice.write);
    if (dgtDevices.length > 0) {
      // connect to board and initialize
      DGTBoard nBoard = new DGTBoard();
      await nBoard.init(client);
      print("DGTBoard connected - SerialNumber: " +
          nBoard.getSerialNumber() +
          " Version: " +

      // set connected board
      setState(() {
        connectedBoard = nBoard;

      // set board to update mode

In action #

To get a quick look, it is used in the follwoing project, which is not open source yet.


Updates soon #

sorry for the lack of information, i will soon:

  • update this readme
  • add an example
  • add some tests maybe
  • make it crossplatform compatible (currently it depends on usb_serial package which makes it android exclusive. Linux, OSX and Windows should be possible aswell)
