What would be the "kotlin approach" to a standard Spring DTO?

public class UserDto {
    @NotNull
    @NotEmpty
    private String firstName;
     
    @NotNull
    @NotEmpty
    private String lastName;
     
    @NotNull
    @NotEmpty
    private String password;
    private String matchingPassword;
     
    @NotNull
    @NotEmpty
    private String email;
     
    // standard getters and setters
}
