• Control the orientation of the board.
• Enable/Disable moves on board.
• Move the pieces either by clicking/tapping or dragging.
• Highlight the valid moves upon clicking/tapping or dragging.
• Draw arrows on the board
• Make a move using the controller programmatically.
• Get the move history, playerToMove, isCheckmate, undo move etc.
• Add a listener using the controller.
• Controller also exposes the game object to control the board further.

Getting started

• Add a dependency to this package (advanced_chess_board) in your pubspec.yaml
• Add an AdvancedChessBoard widget and provide a ChessBoardController object to it.
• Optional : If you to provide custom colors for board you can provide corresponding darkSquareColor and lightSquareColor parameters.
