@@ -18,10 +18,12 @@ There are a few different ways to make custom code accessible in FlutterFlow:
 
 * **[Custom Functions](custom-functions.md):** Custom Dart functions that can be used to set Widget or Action properties. 
 * **[Custom Actions](custom-actions.md):** Custom Dart functions that can be triggered by [Action Triggers](https://docs.flutterflow.io/resources/functions/action-triggers/) or used as nodes in an [Action Flow](https://docs.flutterflow.io/resources/functions/action-flow-editor#action-flow-editor). These are usually `async` functions and are able to import [custom package dependencies](#adding-a-pubspec-dependency).
+* **[Code File](code-file.md):** You can define custom classes, enums, and logic to manage your app’s data and behavior.
 * **[Custom Widgets](custom-widgets.md):** Custom Flutter widgets that can also import [custom package dependencies](#adding-a-pubspec-dependency) and be used in the same way as [Components](https://docs.flutterflow.io/resources/ui/components) throughout your project. 
 * **[Configuration Files](configuration-files.md):** You'll have the ability to edit native files for Android and iOS.
