Challenge 1 / 1

How could we refactor this old way of defining an entity's property to use PHP attributes so that it can be null at initialization?

/**
 * @var string
 * @ORM\Column(type="string")
 */
private $name;

#[ORM\Column()]
private string $name = null;

#[ORM\Column(type: 'string')]
private ?string $name = null;

#[ORM\Column()]
private ?string $name = null;

#[ORM\Column(type: 'string')]
private string $name;
