Not support embedded JsonSerializable class member?

[jaggerwang]

Problem

When the JsonSerializable class has a member which is a instance of a JsonSerializable class. It will a occur the following error.

[VERBOSE-2:dart_error.cc(16)] Unhandled exception:
type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'AccountState'

Code

app.dart

import 'package:meta/meta.dart';
import 'package:json_annotation/json_annotation.dart';

import 'account.dart';

part 'app.g.dart';

@JsonSerializable()
@immutable
class AppState extends Object with _$AppStateSerializerMixin {
  final AccountState account;

  AppState({
    account,
  }) : this.account = account ?? AccountState();

  factory AppState.fromJson(Map<String, dynamic> json) =>
      _$AppStateFromJson(json);

  @override
  String toString() => 'AppState${toJson()}';

  @override
  int get hashCode => account.hashCode;

  @override
  bool operator ==(Object other) =>
      identical(this, other) || (other is AppState && account == other.account);

  AppState copyWith({AccountState account}) => AppState(
        account: account ?? this.account,
      );
}

account.dart

import 'package:meta/meta.dart';
import 'package:json_annotation/json_annotation.dart';

import '../entity/user.dart';
import '../form/account.dart';

part 'account.g.dart';

@JsonSerializable()
@immutable
class AccountState extends Object with _$AccountStateSerializerMixin {
  final UserEntity user;
  final LoginFormData remeberedLogin;

  AccountState({
    user,
    remeberedLogin,
  })  : this.user = user ?? UserEntity(),
        this.remeberedLogin = remeberedLogin ?? LoginFormData();

  factory AccountState.fromJson(Map<String, dynamic> json) =>
      _$AccountStateFromJson(json);

  @override
  String toString() => 'AccountState${toJson()}';

  @override
  int get hashCode => user.hashCode ^ remeberedLogin.hashCode;

  @override
  bool operator ==(Object other) =>
      identical(this, other) ||
      (other is AccountState &&
          user == other.user &&
          remeberedLogin == other.remeberedLogin);

  AccountState copyWith({UserEntity user}) => AccountState(
        user: user ?? this.user,
        remeberedLogin: remeberedLogin ?? this.remeberedLogin,
      );
}

The generated code as follows:

app.g.dart

// GENERATED CODE - DO NOT MODIFY BY HAND

part of 'app.dart';

// **************************************************************************
// JsonSerializableGenerator
// **************************************************************************

AppState _$AppStateFromJson(Map<String, dynamic> json) =>
    new AppState(account: json['account']);

abstract class _$AppStateSerializerMixin {
  AccountState get account;
  Map<String, dynamic> toJson() => <String, dynamic>{'account': account};
}

account.g.dart

// GENERATED CODE - DO NOT MODIFY BY HAND

part of 'account.dart';

// **************************************************************************
// JsonSerializableGenerator
// **************************************************************************

AccountState _$AccountStateFromJson(Map<String, dynamic> json) =>
    new AccountState(
        user: json['user'], rememberedLogin: json['remembered_login']);

abstract class _$AccountStateSerializerMixin {
  UserEntity get user;
  LoginFormData get rememberedLogin;
  Map<String, dynamic> toJson() =>
      <String, dynamic>{'user': user, 'remembered_login': rememberedLogin};
}

It's not calling the embedded member's fromJson method.
