If you use JsonSerializable, Use JsonConverter

class TimestampConverter implements JsonConverter {
  const TimestampConverter();

  @override
  DateTime fromJson(Timestamp timestamp) {
    return timestamp.toDate();
  }

  @override
  Timestamp toJson(DateTime date) => Timestamp.fromDate(date);
}

@JsonSerializable()
class User{
  final String id;
  @TimestampConverter()
  final DateTime timeCreated;

  User([this.id, this.timeCreated]);

  factory User.fromSnapshot(DocumentSnapshot documentSnapshot) =>
      _$UserFromJson(
          documentSnapshot.data..["_id"] = documentSnapshot.documentID);

  Map toJson() => _$UserToJson(this)..remove("_id");
}
