wktToJson function

Object? wktToJson(String typeName, Object? value, Map<String, String>? features, [ AnyTypeResolver? resolver, ])

Converts a decoded WKT message value (snake_case proto field names) to its proto3-JSON representation. resolver is the per-call Any resolver (unused by the structural WKTs, threaded only for signature uniformity).

Implementation

Object? wktToJson(
  String typeName,
  Object? value,
  Map<String, String>? features, [
  AnyTypeResolver? resolver,
]) {
  final wrapped = _wktWrappers[typeName];
  if (wrapped != null) {
    final v = (value is Map) ? value['value'] : null;
    return fieldToJson(v ?? _scalarZero(wrapped), wrapped, features: features);
  }
  switch (typeName) {
    case 'google.protobuf.Timestamp':
      final m = _asWktMap(value);
      _checkTimestampRange(m);
      return timestampToRfc3339(m);
    case 'google.protobuf.Duration':
      final m = _asWktMap(value);
      _checkDurationRange(m);
      return durationToString(m);
    case 'google.protobuf.FieldMask':
      return _fieldMaskToJson(_asWktMap(value));
    case 'google.protobuf.Struct':
      return _structMsgToJson(_asWktMap(value));
    case 'google.protobuf.Value':
      return _valueMsgToJson(_asWktMap(value));
    case 'google.protobuf.ListValue':
      return _listValueMsgToJson(_asWktMap(value));
  }
  return value;
