Hi @DogTwoChen, thank you for taking the time to report your issue and providing the necessary information!

I have tried to reproduce your issue on the latest version of the plugin, but I did not encounter the issue you mention. I tweaked the example app that comes with the plugin by adding

...
  Widget build(BuildContext context) {
    Permission.notification.isGranted.then((value) {
      print(value);
    });
    return Center(
...

to _PermissionHandlerWidgetState. In my case, I get false or true, with no sign of exceptions.

Which version of the plugin are you using? Did you update the Info.plist and Podfile files? Could you provide a minimal reproducible code sample? You can quickly create one by running flutter create and tweaking main.dart, Info.plist and Podfile, or by using the example application that comes with the plugin as a template. You can provide the contents of the files here directly as a comment, or indirectly in a comment by putting it in a GitHub gist.
