## Implementation

    static Future<GenericDocumentResults> startGenericDocumentRecognizer(
        GenericDocumentRecognizerConfiguration config) async {
      try {
        var updatedParameters = config.toJson();
        const defaultJsonName = "GenericDocumentScreen";
        var configuration = await SharedCalls.applyParametersOnDefaultJson(
            defaultJsonName, updatedParameters);
        var result = await SharedCalls.invoke(
            _channel, 'startGenericDocumentRecognizer', configuration);
        if (SharedCalls.wasCanceled(result)) {
          return GenericDocumentResults.canceled();
        }
        var genericResult = GenericDocumentResults.fromJson(jsonDecode(result));
        return GenericDocumentResults.fromGenericDocumentResults(genericResult);
      } catch (e) {
        Logger.root.severe(e);
        return GenericDocumentResults.error(e.toString());
      }
    }
