JsonKey annotation in superclass is not being used for overriden getters

[hacker1024]

Consider a structure like the following:

abstract class MyBaseClass {
  @JsonKey(name: 'myCustomGetterName');
  String get myGetter;

  @JsonKey(name: 'myCustomFieldName');
  final String myField;
}

@JsonSerializable(createFactory: false)
class MySuperclass implements MyBaseClass {
  @override
  String get myGetter => 'myGetterValue';

  @override
  final String myField = 'myFieldValue';

  Map<String, dynamic> toJson() => _$MySuperclassToJson(this);
}

I'd expect to see a JSON result like this:

{
  "myCustomGetterName": "myGetterValue",
  "myCustomFieldName": "myFieldValue"
}

Instead, the getter name isn't inherited, and I get this:

{
  "myGetter": "myGetterValue",
  "myCustomFieldName": "myFieldValue"
}

@kevmoo any updates on this?

Sadly, @emme1444 – there's no good way to fix this without potentially breaking folks due to a change in behavior.

We'll have to wait until the next breaking release.
