follow up - is there a way to bring up the request permissions popup again after denying the request? why does denying it once permanently deny?

You should add some logic to manage this in iOS to prevent the crash.

PermissionStatus permission = await PermissionHandler().checkPermissionStatus(PermissionGroup.contacts);
if (permission == PermissionStatus.denied && Platform.isIOS) {
    // do not request permissions again.
}

any news on that?

Running this with the latest Flutter and permission_handler version does not result in an error.

Please resubmit a new issue when a problem occurs.
