Implementation

factory YMap.fromJson(Object? json_) {
  final json = json_ is Map
      ? _spec.fields.map((f) => json_[f.label]).toList(growable: false)
      : json_;
  return switch (json) {
    [final ref] || (final ref,) => YMap(
        ref: ref! as int,
      ),
    _ => throw Exception('Invalid JSON $json_')
  };
}
