Squares

A flexible chessboard widget for Flutter.

Squares is a chessboard like you've never seen before. Or more accurately, it is a chessboard very much like the ones you have seen before, but one that can do a pretty wide variety of things.

It is a UI package only, meaning it doesn't handle game logic. The Bishop package is recommended for game logic, and there is an example in the Squares repository that demonstrates how the two can be used together.

Squares has a stateless Board widget that can used to display a complete board representation, and can be integrated at a low level with your own UI logic. However, the more likely use case involves the BoardController widget, which implements all of the piece selection and movement logic you're likely to need, including premoves and piece promotion.
