Goban #

Goban

Customizable Go board widget for Flutter.

Usage #

Initialize a GobanController like so:

gobanController = GobanController(boardSize: BoardSize.Thirteen);

Then subscribe to the move stream:

gobanController.gobanStream.stream.listen((Position position) {
    // A move at 'position' was played
    // Decide what to do here
});

Whenever an intersection is clicked, the above method will fire.

Goban does not have any game logic; this is by design. Goban make no assumptions on what you want to do, so that it can be used for all purposes. Maybe you want to use it for Tsumego purposes, or maybe you want to use it for online multiplayer. Both of these required different logic, therefore Goban delegates all game logic responsibilities to the client.

For example, a simple local board would be:

player = Player.Black;

gobanController.gobanStream.stream.listen((Position position) {
    // A move at 'position; has been made.
    var clickedPlayer = gobanController.getPlayerFromPosition(pos); // Get the intersection at 'position'
    if (clickedPlayer == Player.Empty) { // If the intersection is empty;
        var move = Move(player, pos); // Create move

        gobanController.addMove(move); // Make the move on the goban.

        setState(() {
            player = player == Player.Black ? Player.White : Player.Black; // Other players' turn
        });
    }
});

Please see here for a more concrete example.

Customization Options #

gobanController = GobanController(
    boardSize: BoardSize.Nine,
    gobanTheme: GobanTheme(
        stoneThemes: StoneThemes(
            blackStoneTheme: BlackStoneTheme(
                stoneColor: Colors.black45, borderColor: Colors.black),
            whiteStoneTheme: WhiteStoneTheme(
                borderColor: Colors.white, stoneColor: Colors.tealAccent)),
        boardTheme: BoardTheme(
            boardColor: Colors.yellow,
