use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Item extends Model
{
    use HasFactory;

    // ...
}

2. Use it like this:
	
	$item = Item::factory()->make(); // Create a single App\Models\Item instance

	// or

	$items = Item::factory()->count(3)->make(); // Create three App\Models\Item instances

3. Use create method to persist them to the database:

  $item = Item::factory()->create(); // Create a single App\Models\Item instance and persist to the database

  // or

  $items = Item::factory()->count(3)->create(); // Create three App\Models\Item instances and persist to the database
