# Manually save annotations in Flutter

Nutrient automatically saves changed, created, or deleted annotations and bookmarks at several points. You can also trigger a save manually through the loaded document’s controller, which is available from the `NutrientDocumentView` `onControllerReady` callback:

```dart

await controller.document.save();

```
