Can't register a device using Flutter with .NET backend

[FahadZaheerAslam]

I've followed the tutorial on Microsoft website for implementing Azure Notification Hub with Flutter using .NET backend. (https://docs.microsoft.com/en-us/azure/developer/mobile-apps/notification-hubs-backend-service-flutter#prerequisites).

However after completing the tutorial and trying to run my application app, I'm receiving this error on flutter : MissingPluginException(No implementation found for method getDeviceId on channel com.company.myproject/deviceinstallation)

I haven't edited my code at all and have only copied and pasted from the tutorial.
