## QuestionnaireForm [#questionnaireform]

```dart
class QuestionnaireForm extends StatefulWidget
```

Renders a FHIR Questionnaire as a paged Flutter form.

The form builds a FHIR `QuestionnaireResponse` and passes it to [`onSubmit`](#questionnaireformonsubmit).
Use `ovok.questionnaireResponses.submit` in that callback to save it.
