Could not generate toJson code for because of type

When attempting to generate my freezed data models with the toJson function i get the following error.

Could not generate toJson code for merchants because of type Merchant.

This started happening in Flutter 2.0 and up. The type is defined and compiles fine, when I try to generate the code I get that error. I am using:

Flutter 2.0.3

freezed: 0.12.7 freezed_annotation: 0.12.0

json_annotation: 3.1.1 json_serializable: 3.5.1

build_runner: 1.11.1

I have also updated everything to the latest using a null-safe flutter project and it still happens so I know it's not a null safety issue. Or at least I can assume that given it doesn't work when the project is updated to be null-safe.

This is the smallest reproducible set of models

@freezed
abstract class SearchInformation with _$SearchInformation {
  SearchInformation._();

  factory SearchInformation({
    String query,
    // List<CartProduct> products,
    List<Merchant> merchants,
  }) = _SearchInformation;

  bool get hasSearchResults =>
      (products != null && products.isNotEmpty) ||
      (merchants != null && merchants.isNotEmpty);

  int get searchCount => (products?.length ?? 0) + (merchants?.length ?? 0);

  factory SearchInformation.fromJson(Map<String, dynamic> json) =>
      _$SearchInformationFromJson(json);
}

@freezed
abstract class Merchant with _$Merchant {
  factory Merchant({
    int id,
  }) = _Merchant;
}

I have an issue for it here. Which hasn't been answered in over 21 days or even just looked at. I don't know if this is in freezed or in json serializable. Here is a --verbose log for the builder output when the error happens. I've removed some duplicate logs to keep it shorter since it's a lot of text.

I want to be able to generate my models code without getting a type error for a type already defined.

I found out what the problem is. For each of the models I had some additional from json logic I wrote it like this.

 factory Merchant.fromJson(Map<String, dynamic> incomingJson) {
    var jsonPayload = Map<String, dynamic>.from(incomingJson);

    if (jsonPayload['availableTimes'] is String) {
      jsonPayload['availableTimes'] =
          json.decode(jsonPayload['availableTimes']);
    }

    if (jsonPayload['territoryAvailableTimes'] is String) {
      jsonPayload['territoryAvailableTimes'] =
          json.decode(jsonPayload['territoryAvailableTimes']);
    }

    if (jsonPayload['cuisines'] is String) {
      jsonPayload['cuisines'] = json.decode(jsonPayload['cuisines']);
    }

    return _$MerchantFromJson(jsonPayload).copyWith(
      // Convert the bool to an integer and set it to the hideCustomizations value
      hideCustomizations: boolToIntOrInt(jsonPayload['hideCustomizations']),
    );
  }

This caused the generator to ignore the json code generation. Which I discovered from this comment. So I updated all my custom fromJson functions to this.

factory Merchant.fromJson(Map<String, dynamic> incomingJson) =>
      _customFromJson(incomingJson);

  static Merchant _customFromJson(Map<String, dynamic> incomingJson) {
    var jsonPayload = Map<String, dynamic>.from(incomingJson);

    if (jsonPayload['availableTimes'] is String) {
      jsonPayload['availableTimes'] =
          json.decode(jsonPayload['availableTimes']);
    }

    if (jsonPayload['territoryAvailableTimes'] is String) {
      jsonPayload['territoryAvailableTimes'] =
          json.decode(jsonPayload['territoryAvailableTimes']);
    }

    if (jsonPayload['cuisines'] is String) {
      jsonPayload['cuisines'] = json.decode(jsonPayload['cuisines']);
    }

    if (jsonPayload['subVendors'] is String) {
      jsonPayload['subVendors'] = json.decode(jsonPayload['subVendors']);
    }

    return _$MerchantFromJson(jsonPayload).copyWith(
      // Convert the bool to an integer and set it to the hideCustomizations value
      hideCustomizations: boolToIntOrInt(jsonPayload['hideCustomizations']),
    );
  }

The important part is to ensure that fromJson function has => otherwise it will be ignored for some reason.
