advanced_chess_board 1.1.1

A modern looking chess board with advanced features.

advanced_chess_board

It's a chess board developed in using plain flutter widgets without using images of a board. So you can customize board color as per your need. It uses a ChessBoardController to control the board state.

Features

• You can load the board with custom FEN.
• Control the orientation of the board.
• Enable/Disable moves on board.
• Moves the pieces either by clicking/tapping or dragging.
• Highlighting the valid moves upon clicking/tapping or dragging.
• Make a move using the controller programmatically.
• Get the move history, isCheckMate, undo move etc.
• 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.
• Optional : By default board orientation is for white. You can provide optional boardOrientation to be either black or white.
