# Inspector Addon

The `InspectorAddon`, _built on the ['inspector'](https://pub.dev/packages/inspector) package_, enhances Widgetbook by enabling widget property inspection, such as colors, sizes, and padding, directly in the Workbench.

## Usage

```dart title=widgetbook/lib/main.dart
class WidgetbookApp extends StatelessWidget {
  const WidgetbookApp({super.key});

  @override
  Widget build(BuildContext context) {
    return Widgetbook(
      // ...
      addons: [
        InspectorAddon(), // [!code highlight]
      ],
    );
  }
}
```

## Order

Since the [order of addons](/addons/overview#order-of-addons) matters, here are some guidelines to follow when using the `InspectorAddon`:

Addons that should come before the `InspectorAddon`:

- `ViewportAddon`
- `DeviceFrameAddon`
