Question Regarding Freezed V3 and Classic Classes

[garysm]

I've been playing around with using classic classes in Freezed V3, and I noticed that the toJson() method is not automatically available to normal Dart classes using Freezed when adding factory Model.fromJson(Map<String, dynamic> json) => _$ModelFromJson(json);. I noticed a snippet on #1237 that manually added toJson, but that wasn't readily visible in the docs if that change is recommended.

My class:

import 'package:freezed_annotation/freezed_annotation.dart';

part 'sms_page.freezed.dart';
part 'sms_page.g.dart';

@JsonSerializable()
@freezed
class SMSPage with _$SMSPage {
  const SMSPage({
    required this.id,
    required this.pageTitle,
    required this.pageSlug,
    required this.userId,
    required this.associatedPhoneNumberId,
    this.customizations = const {},
    required this.dateCreated,
    this.isPublic = true,
    this.accessCode,
  });

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

  @override
  final String id;
  @override
  final String pageTitle;
  @override
  final String pageSlug;
  @override
  final String userId;
  @override
  final String associatedPhoneNumberId;
  @override
  final Map<String, dynamic> customizations;
  @override
  @JsonKey(fromJson: TimeStampUtils.timestampFromJson, toJson: TimeStampUtils.timestampToJson)
  final DateTime dateCreated;
  @override
  final bool isPublic;
  @override
  final String? accessCode;
}

abstract is now required for data classes

abstract class SMSPage with _$SMSPage {
