Consider the following dart class using freezed:
@freezed
class Example with _$Example {
const factory Example(
{String? fieldA, int? fieldB}) = _Example;
factory Example.fromJson(Map<String, dynamic> json) => _$ExampleFromJson(json);
}
If you were to deserialize the following json:
{
"fieldA": "test",
"fieldB": 9,
"fieldC": 100
}
and then serialize it, it would end up like this:
{
"fieldA": "test",
"fieldB": 9
}
How can I preserve fieldC or any unknown field upon deserialization? In C# there is an annotation called ExtensionData (either for system.text or for newtonsoft) that held all the unserialized data. Is there an equivalent in freezed/json_serializable? If not, is there some way to workaround this?
