serialize method

@override Iterable<Object?> serialize(Serializers serializers, Shape object, { FullType specifiedType = FullType.unspecified, })

Serializes object.

Use serializers as needed for nested serialization. Information about the type being serialized is provided in specifiedType.

Returns an Iterable of values that can be represented as structured JSON: booleans, integers, doubles, Strings and Iterables.

TODO(davidmorgan): document the wire format.

Implementation

@override
Iterable<Object?> serialize(
  Serializers serializers,
  Shape object, {
  FullType specifiedType = FullType.unspecified,
}) {
  final map =
      serializers.serialize(
            object,
            specifiedType: FullType(object.getType().type),
          )
          as Map<String, Object?>;
  map['type'] = object.getType().name;
  map.removeWhere(
    (key, value) =>
        value == null ||
        (value is Map && value.isEmpty) ||
        (value is List && value.isEmpty),
  );
  return map.entries.expand((entry) => [entry.key, entry.value]);
}
