[Nutrient Flutter SDK 3.6](https://www.nutrient.io/blog/pspdfkit-3-6-flutter-measurement-tools/) introduces named optional parameters for the `present` method. This means that you can pass the `configuration` parameter as a named parameter. To update your code, change the `present` method calls as follows:

```diff

-  await PSPDFKit.present(

-    documentPath,

-    configuration,

-  );

+  await PSPDFKit.present(

+    documentPath,

+    configuration: configuration,

+  );

```
