    final context = VContext(context: vComponent.context, key: _key);
    if (!context.hasKey(key)) {
      try {
        final value = context.init(key, init);
        return value;
      } catch (e, s) {
        throw WrappedException(
            "An error occurred while executing the method '$InheritedProperty.add($key)' for component '$vComponent'",
            e,
            s);
      }
    } else {
