# Auto save PDF files in Flutter

Nutrient Flutter SDK automatically saves a modified open document to your device’s local storage. You can also manually save the changes. Note that files are saved locally on your device, and no server is required.

## Auto save

Nutrient will automatically save changed, created, or deleted annotations and bookmarks on several occasions. In practice, this means that automatic saving will be performed when:

- The application goes into the background

- A configuration change occurs (for example, change of device orientation, change of locale, added keyboard)

- The PDF view is fully covered by another view

- A document will be digitally signed

### Disabling automatic saving

Autosave is enabled by default. To disable autosave, set the `disableAutosave: true` configuration to the Nutrient Flutter SDK using the `PdfConfiguration` object, like so:

```dart

PdfConfiguration(disableAutosave: true);

```

## Manual save

Saving can always be triggered manually by calling `save()`, like this:

```dart

await pdfDocument.save();

```

To manually save documents using the Nutrient Flutter SDK, ensure that the `documentPath` passed to either `NutrientView` or `Nutrient.present` is a writable path.
