✅ What is reason of null! here?

I have this property in entity model:

[Required]
[MinLength(1)]
[MaxLength(100)]
public string Identity { get; set; } = null!;

[Required]
[MinLength(1)]
[MaxLength(100)]
public string Identity { get; set; } = null!;

[Required]
[MinLength(1)]
[MaxLength(100)]
public string Identity { get; set; } = null!;

[Required]
[MinLength(1)]
[MaxLength(100)]
public string Identity { get; set; } = null!;
