GridWalkable<E> class final Grids

Adapts a Grid into a WeightedWalkable.

Each node in the grid is automatically connected to its neighbors, based on the configuration provided; the neighbors are connected with the weight that is a tuple of both the source and target node's values.

Example

final grid = ListGrid.fromRows([
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9],
]);

final graph = GridWalkable(grid);
