Usage #
Sector offers a powerful toolkit for graphs, grids, pathfinding, and more.
Graphs #
Create a graph and add edges:
final graph = Graph<String>();
graph.addEdge(Edge('a', 'b'));
graph.addEdge(Edge('b', 'c'));
print(graph.roots); // ['a']
print(graph.successors('b')); // ['c']

Grids #
Create a grid and update cells:
enum Tile {
wall,
floor,
}
// Create a 5x8 grid filled with `Tile.wall`.
//
// When resizing a grid, the `empty` value is used to fill the new cells.
final grid = Grid.filled(5, 8, empty: Tile.wall);
// Itereate over the grid.
for (final row in grid.rows) {
for (final cell in row) {
print(cell);
}
}

Pathfinding #
Use built-in pathfinding algorithms or write your own:
final graph = Walkable.linear(['a', 'b', 'c']);
final path = breadthFirstSearch(graph, 'a', Goal.node('c'));
print(path); // Path(['a', 'b', 'c'])
