fromJsonWith<T extends dynamic> static method

T fromJsonWith<T extends dynamic>(Map<String, dynamic> json, T create(), List<String> propertyNames, { Map<String, dynamic Function(Map<String, dynamic>)>? embeddedCreators, })

Hydrate a RealmObject from JSON using explicit property names.

Note: Consider using fromEJson() instead for automatic nested object handling.

Provide create to construct a new instance of T. For embedded objects, provide nested creators.

Example:

final person = RealmJson.fromJsonWith<Person>(
  json,
  () => Person(ObjectId(), '', 0),
  ['name', 'age', 'address'],
  embeddedCreators: {
    'address': (json) => Address(json['street'], json['city'])
  }
);

Implementation

static T fromJsonWith<T extends RealmObject>(
  Map<String, dynamic> json,
  T Function() create,
  List<String> propertyNames, {
  Map<String, dynamic Function(Map<String, dynamic>)>? embeddedCreators,
}) {
  final obj = create();

  for (final name in propertyNames) {
    if (!json.containsKey(name)) continue;

    try {
      final jsonValue = json[name];

      // Handle embedded objects
      if (embeddedCreators?.containsKey(name) == true &&
          jsonValue is Map<String, dynamic>) {
        final embedded = embeddedCreators![name]!(jsonValue);
        RealmObjectBase.set(obj, name, embedded);
      } else {
        RealmObjectBase.set(
          obj,
          name,
          _fromJsonValue(jsonValue, embeddedCreators),
        );
      }
    } catch (_) {
      // Property conversion failed - skip it
    }
  }

  // Handle _id/id mapping
  final id = json['_id'] ?? json['id'];
  if (id != null) {
    try {
      RealmObjectBase.set(obj, 'id', _fromJsonValue(id, embeddedCreators));
    } catch (_) {
      try {
        RealmObjectBase.set(obj, '_id', _fromJsonValue(id, embeddedCreators));
      } catch (_) {}
    }
  }

  return obj;
}
