# Manually save annotations in Flutter

Nutrient will automatically save changed, created, or deleted annotations and bookmarks on several occasions. Additionally, saving can always be triggered manually by calling `save()`, like this:

```dart

await Nutrient.save();

```

When using the `NutrientView` widget, you can also call `save()` on the `PdfDocument` instance, like this:

```dart

await pdfDocument.save();

```
