`class BaseUser extends Equatable {
String nick;
int uid;
String avatar;
int gender;
int age;

BaseUser({this.nick, this.uid, this.avatar, this.gender, this.age}): super([nick, uid, avatar, gender, age]);

Map<String, dynamic> toJson() => serializer.toMap(this);

static final serializer = BaseUserSerializer();
static BaseUser fromMap(Map map) => serializer.fromMap(map);
static BaseUser fromString(String source) {
var map = json.decode(source);
return map is Map ? fromMap(map) : null;
}

String toString() => toJson().toString();
}`

but base_user.jser.dart method(frommap)
BaseUser fromMap(Map map) { if (map == null) return null; final obj = BaseUser(); obj.nick = map['nick'] as String; obj.uid = map['uid'] as int; obj.avatar = map['avatar'] as String; obj.gender = map['gender'] as int; obj.age = map['age'] as int; return obj; }

why ---> obj.props.addAll(iterable)

sorry My English is so poor~~
