sudoku api

Simple, dart API for Sudoku puzzles #
Introduction #
sudoku_api simplifies the generation, interaction, and management
of Sudoku Puzzles.
Well, how does it do that?

Contains a Built-in solver for generating new puzzles, or solving existing ones
Utilizes and exposes event streams for grid interactions (e.g. cell value changed), and puzzle states
Exposes a bunch of neat, easy to use models manipulating Cells, Positions, Grids, and even Patterns of a Sudoku puzzle

What is Sudoku?

... a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids (segments) that compose the grid contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.

Example #

import 'package:sudoku_api/Puzzle.dart';

void main() {

PuzzleOptions puzzleOptions = new PuzzleOptions(patternName: "winter");

Puzzle puzzle = new Puzzle(puzzleOptions);

puzzle.generate().then((_) {
print("=====================================");
print("Your puzzle, fresh off the press:");
print("-------------------------------------");
printGrid(puzzle.board());
print("=====================================");
print("Give up? Here's your puzzle solution:");
print("-------------------------------------");
printGrid(puzzle.solvedBoard());
print("=====================================");
});
}
