memberGet method

@override dynamic memberGet(dynamic varName, { String? from, bool isRecursivelyGet = false, })

isSelf means wether this is called by the struct itself, or a recursive one

Implementation

@override
dynamic memberGet(dynamic varName,
    {String? from, bool isRecursivelyGet = false}) {
  if (varName == null) {

  }
  if (varName == InternalIdentifier.prototype) {
    return prototype;
  }

  dynamic value;
  final getter = '${InternalIdentifier.getter}$varName';
  final constructor = varName != id
      ? '${InternalIdentifier.namedConstructorPrefix}$varName'
      : InternalIdentifier.defaultConstructor;

  if (_fields.containsKey(varName)) {
    if (interpreter.lexicon.isPrivate(varName) &&
        from != null &&

    }
    value = _fields[varName];
  } else if (_fields.containsKey(getter)) {
