Json_serializable.dart: How to serialize the mongodb '_id' ?

[Yaxian]

Hi,
I have a problem to serialize mongodb document, because of the _id field.
For example,
account collection is

{ _id: 1, name: 'test'}

account.dart file is like below:

import 'package:json_annotation/json_annotation.dart';
part 'account.g.dart';

class Account extends Object with _$AccountSerializerMixin {
  // final String id;
  @JsonKey(name: '_id')
  String _id;
  String name;


  Account(
      this._id,
      this.name,
);
  factory Account.fromJson(Map<String, dynamic> json) =>
      _$AccountFromJson(json);
}

it will fail to run flutter packages pub run build_runner watch. Any idea about the problem?

Oh, I resolved it:

@JsonKey(name: '_id')
String id;

 Account(
      this.id,
      this.name,
)
