# fromMap method Null safety

LinkEntity? fromMap(

1. Object? o,
2. {Map<String, String>? newDocumentIds}

)

## Implementation

    static LinkEntity? fromMap(Object? o, {Map<String, String>? newDocumentIds}) {
      if (o == null) return null;
      var map = o as Map<String, dynamic>;

      var actionFromMap = map['action'];
      if (actionFromMap != null) {
        actionFromMap =
            ActionEntity.fromMap(actionFromMap, newDocumentIds: newDocumentIds);
      }

      return LinkEntity(
        linkText: map['linkText'],
        action: actionFromMap,
      );
    }
