当试图用toJson函数生成冻结的数据模型时，我得到了以下错误。
Could not generate toJson code for merchants because of type Merchant.
这在Flutter 2.0及更高版本中开始发生。类型被定义并编译得很好，当我试图生成代码时，我会遇到错误。我正在使用：
Flutter 2.0.3
冷冻：0.12.7冷冻_注释：0.12.0
json_annotation:3.1.1json_serializable：3.5.1
build_runner:1.11.1
我还使用零安全颤振项目将所有内容更新到了最新版本，这种情况仍然存在，所以我知道这不是零安全问题。或者，至少我可以假设，当项目更新为空安全时，它不起作用。
这是最小的可复制模型集
@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;
}
我有一个问题。这已经21天没有答案了，甚至只是看了一眼。我不知道这是冷冻的还是json可序列化的。以下是错误发生时生成器输出的详细日志。我删除了一些重复的日志以使其更短，因为它是大量的文本。

这导致生成器忽略json代码的生成。这是我从这条评论中发现的。所以我更新了Json函数中的所有自定义函数。
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']),
);
}
重要的部分是确保fromJson函数具有=>，否则由于某种原因它将被忽略。
