# Text selection events and notifications

Nutrient Flutter SDK emits events when users select text in a document.

## Text selection events

Subscribe to `controller.events.textSelectionChanged` from the `NutrientDocumentView` `onControllerReady` callback to respond to text selection changes. The `TextSelectionChangedEvent` exposes the selected text through `event.selectedText`. This value is `null` when the user clears the selection.

Use the following listener to respond to text selection changes:

```dart

NutrientDocumentView(
  documentPath: documentPath,
  onControllerReady: (controller) {
    controller.events.textSelectionChanged.listen((event) {
      print('Text selection changed: ${event.selectedText}');
    });
  },
)

```

For advanced customization, use the Nutrient native and web SDKs. Refer to the [Nutrient Flutter SDK customization](https://www.nutrient.io/guides/flutter/customize.md) guide and the following guides for more information:
