Future Plans

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.
