TutorialEntryEntity? fromJsonString(

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

)

    static TutorialEntryEntity? fromJsonString(String json,
        {Map<String, String>? newDocumentIds}) {
      Map<String, dynamic>? generationSpecificationMap = jsonDecode(json);
      return fromMap(generationSpecificationMap, newDocumentIds: newDocumentIds);
    }
