    Instead of adding null keep them as empty string
    ex-

    {
 'class':''
}

    You need to use null safety in your model class.

    class Profile{
  String? photo;

  Profile({
    this.photo,
  });

  Map<String, dynamic> toMap() {
    return {
      'photo': photo,
    };
  }

  factory Profile.fromMap(Map<String, dynamic> map) {
    return Profile(
      photo: map["profile"]['photo'] ?? "",
    );
  }
}
