A board that can be a Sudoku Puzzle (with only one possible solution) or not. Any non-zero value in the set of initial values for the board becomes a read-only position, and as such, cannot be modified.

Functions

findSolutions(Board puzzle, {FindSolutionsProgress? progressCallback, int maxSolutions = 1, TimeoutTracker? tracker}) → List<Board>
Finds solution(s) for a given puzzle board within timeoutMillis interval that defaults to one day.
generateSudokuPuzzle({PuzzleDifficulty level = PuzzleDifficulty.medium, int dimension = 9, int timeoutSecs = 15, GeneratorProgress? onProgress}) → (Board?, String?)
Generates a new Sudoku puzzle with the specified difficulty level and dimensions. A Sudoku board is a puzzle when it is guaranteed to have only one solution.
