In recipes_grid_view.dart, replace the gridDelegate parameter with the following:

const SliverGridDelegateWithMaxCrossAxisExtent(
  maxCrossAxisExtent: 500.0),

Recall that the GridView is set to scroll in the vertical direction. That means the cross axis is horizontal. According to Flutter’s documentation, maxCrossAxisExtent sets the maximum extent of tiles in the cross axis. So making maxCrossAxisExtent greater than the device’s width would allow for only one column!
