Sudoku Solver in Dart Language

Sudoku Solver is a Dart package that provides a Sudoku puzzle solver using the backtracking algorithm. It allows you to input Sudoku puzzles as 2D grids and find solutions for them.

Features

• Solve Sudoku puzzles of various difficulty levels.
• Visualize the solving process with a customizable animation delay.
• Easy-to-use API for solving Sudoku puzzles.
• Input Sudoku grids as 2D lists of integers.
• Check the validity of a Sudoku grid.
• Print Sudoku grids to the console.

Usage

Here's an example of how to use the Sudoku Solver package:

void main(List<String> arguments) {
  (SudokuSolver()..solve(grid))
      .streamController
      .stream
      .listen((dynamic gtid) => SudokuSolver.printGrid(gtid));
}

final List<List<int>> grid = <List<int>>[
  <int>[0, 0, 4, 0, 5, 0, 0, 0, 0],
  <int>[9, 0, 0, 7, 3, 4, 6, 0, 0],
  <int>[0, 0, 3, 0, 2, 1, 0, 4, 9],
  <int>[0, 3, 5, 0, 9, 0, 4, 8, 0],
  <int>[0, 9, 0, 0, 0, 0, 0, 3, 0],
  <int>[0, 7, 6, 0, 1, 0, 9, 2, 0],
  <int>[3, 1, 0, 9, 7, 0, 2, 0, 0],
  <int>[0, 0, 9, 1, 8, 2, 0, 0, 3],
  <int>[0, 0, 0, 0, 6, 0, 1, 0, 0],
];

In this example, we create a Sudoku grid as a 2D list of integers with empty cells represented as 0. We then use the SudokuSolver class to solve the puzzle and visualize the solving process.
