If needed, you can wrap what depends on the state with the function `onWrap`.
```dart
@override
Widget onWrap(BuildContext context, Widget child) {
return Scaffold(
appBar: AppBar(
title: const Text('Title'),
),
body: child,
);
```
> Note: you can override `onBuild`, but also `onListen`, `shouldBuildWhen` and `shouldListenWhen` methods. > Note: you can override `onBuild`, but also `onListen`, `shouldBuildWhen` and `shouldListenWhen` methods.
