My views are all created in the project common to the two platforms then the notifications are managed in the project of each platform, I followed the tutorial from Microsoft for the creation of notification https://docs.microsoft.com/fr-fr/xamarin/xamarin-forms/data-cloud/azure-services/azure-notification-hub#configure-the-android-application-for-notifications.
In fact, I would like to do exactly what it does in this tutorial https://docs.microsoft.com/fr-fr/azure/notification-hubs/push-notifications-android-specific-devices-firebase-cloud-messaging but without having to manage it in each platform.
As for the back-end to send notifications, I used this tutorial: https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/notification-hubs/notification-hubs-php-push-notification-tutorial.md.
So, how can I create this view common to both platforms so that the user can choose the tags they want to receive and retrieve this configuration in each platform? I hope I was clear enough ^ _ ^
Thanks in advance for your help.
