squares 1.2.1

A flexible chessboard widget for Flutter. Visually customisable, with support for many chess variants.

1.2.1

• DragTargetFeedback: used to build visual feedback for pieces hovering over drag targets in BoardTargets / Board / BoardController.

1.2.0

• Now requires Dart 3.
• BoardController can now take overlays and underlays as parameters, and passes them through to Board.
• BoardBuilder now takes a parameter forceSquareAlignment, which defaults to true, and forces elements to be aligned to their squares (previously this was not the case).
• SquareBuilder functions (such as those used by BoardBuilder) now return Widget?, i.e. they can return null. BoardBuilder will build an empty container in this case.
• BoardBuilder.index(): a BoardBuilder that uses an index, rather than rank and file.
• InputOverlay: an easy way to support common gestures like right clicks and long presses.
• SquareNumberOverlay: an overlay for debugging that shows the square index.
• LabelConfig is now exported correctly with the rest of the package.

1.1.6

• dragFeedbackSize and dragFeedbackOffset parameters in Hand (thanks @callumbeaney).

1.1.5

• Fixed premoves not getting cleared when the board updates after a move, in BoardController.
• Fixed check/mate squares not being shown for moves where the check square is the same as the destination, as is the case for variants like king of the hill.

1.1.4

• Fixed janky resizing behaviour on web (thanks @deathcoder).
• Example: opponent type options (AI, random mover, human).

1.1.3

• Fixed breaking conflict between Flutter 3.7 and the Badges package.
• Now using Badges 3.0.x, but with the intent to drop the dependency and move to the material badge at some point.

1.1.2

• Fixed a bug that would result in incorrect piece selections for optional promotion moves, e.g. Grand Chess (thanks @malaschitz).
• theme parameter is now optional everywhere.

1.1.1

• Drag permissions changes: Board and BoardPieces now take a dragPermissions param that defines which piece colours can be dragged. BoardController implements behaviour that only allows the player's pieces to be dragged (as defined by playState).
• Board editor improvements in the example.

1.1.0

• The Xiangqi Update!
• BoardConfig - used to configure the way BoardBackground is drawn.
• Two Xiangqi piece sets and one background image.
• Parameter on Board/BoardConfig/BoardPieces to allow padding pieces within their squares - piecePadding.

1.0.5

• Fixed move string parsing for moves from ranks larger than 9 (thanks @malaschitz).
• Fixed duplicate pieces appearing in piece selector for castling gating moves.

1.0.4

• Rank and file labels on the board using LabelOverlay.
• Fixed a bug that would cause custom piece sets to sometimes be misaligned.
• MarkerTheme.cross() - marker that builds a cross in a square.

1.0.3

• Board editor page in example.
• Added a way for external dragged pieces (e.g. from board editor, hands) to land on pieces.
• Improvements to Hand widget.

1.0.2

• Support for overlays and underlays in Board.
• BoardOverlay, which draws widgets on squares, and PieceOverlay.
• BoardController now shows translucent premove promo/gate pieces.
• Fixed a bug that stopped white playing hand drops.
• Fixed various bugs with colours of pieces in selectors.
• BoardState.player is now turn, for clarity.

1.0.1

• Fixed piece selectors not closing after premoves.
• Premoves can now be cancelled by selecting another square.
• MarkerTheme.corners() - piece marker that draws triangles in the corners of the square.
• BoardController.promotionBehaviour - this allows different behaviours to be specified: always show the selector (default), always auto select the best piece, or auto select only for premoves.
• BoardController.pieceHierarchy - allows the relative hierarchy of pieces to be specified, for use in auto promotion and ordering the pieces in the selector.

1.0.0

• Major refactor with improved stability, better performance and better organised code.
• Board is now composed of separate background, target and piece layers.
• BoardController has better composed logic.
• There are many breaking changes here, but if you're exclusively using BoardController you will likely only run into a few parameter name changes. Board has changed completely.
