toJSON method Null safety

  1. @override
dynamic toJSON(
  1. Object? object,
  2. SerializationContext context
)
override

Implementation

@override
dynamic toJSON(Object? object, SerializationContext context) {
  dynamic convert(value) =>
      value != null ? _transformValue(value, context) : null;
  return (object is Iterable)
      ? object.map(convert).toList()
      : convert(object);
}
