A shogi board widget for Flutter. This widget can be used in conjunction with shogi to render static game board positions, tsume problems or shogi castles.

As this package is still highly experimental, 0.0.x versioning is used. shogi is also in active development and similarly versioned.

To import this package, simply add flutter_shogi_board as a dependency in pubspec.yaml

dependencies:
  flutter:
    sdk: flutter
  flutter_shogi_board:

import 'package:flutter/material.dart';
import 'package:flutter_shogi_board/flutter_shogi_board.dart';
import 'package:shogi/shogi.dart';

void main() {
  runApp(
    MaterialApp(
      home: Scaffold(
        body: Padding(
          padding: const EdgeInsets.all(8.0),
          child: Center(
            child: ShogiBoard(
              gameBoard: ShogiUtils.initialBoard,
            ),
          ),
        ),
      ),
    ),
  );
}

For more information, see the Flutter app in the example directory. This example is also hosted online.

This widget renders a shogi game board using a GameBoard and ShogiBoardStyle. Unless style.maxSize is set, it fills its maximum size to that of its parent. The board pieces are rendered as text.

A model used to paint a ShogiBoard.

The ShogiBoardStyle to apply to descendant ShogiBoard widgets without an explicit style.

DefaultShogiBoardStyle(
  style: ShogiBoardStyle(
    cellColor: BoardColors.brown,
  ),
  child: MaterialApp(
    ...

This package grew out of my desired to visualize shogi castles in Flutter, and with no game board widget or even a shogi engine available, I decided to roll my own.

For the future I would like to utilize this widget not just for displaying static game boards, but also for tsume problems, thus user interaction may be considered.
