final
onGeolocationPermissionsHidePrompt → (void Function(InAppWebViewController controller)?)
Notify the host application that a request for Geolocation permissions, made with a previous call to onGeolocationPermissionsShowPrompt has been canceled. Any related UI should therefore be hidden.

On non-secure origins geolocation requests are automatically denied.
final
onJsAlert → (Future<JsAlertResponse?> Function(InAppWebViewController controller, JsAlertRequest jsAlertRequest)?)
