[Cloud Messaging] Does this package support handling of locally sent notifications?

[JayMansel]

Hello,

More of a question but notice we don't have a Discussions section here.

I've set up this plugin in our .Net MAUI 9 app. All seems good for receiving and handling notifications from FCM.

However, in our app we can 'defer' a notification, i.e. we receive a notification, tap on it, the app opens and prompts us if we want to action this notification. We can defer the notification, which in turn creates a local notification (a copy of the notification received from FCM) so the user has a reminder to check later.

Here is the code where we create and send our local notification:

const int SHARED_CHANNEL_ID = 2; // any unknown notification_type get re-posted on this channel
const string SHARED_CHANNEL_NAME = "shared";

        Dictionary<string, int> knownNotificationTypes = new Dictionary<string, int>
            {
               { SHARED_CHANNEL_NAME, SHARED_CHANNEL_ID },
               { "events",            3 },
               { "eventsrepost",      0 }, // channel 0 is used for remote notifications, so reposts on the incoming channel
               { "permits",           5 },
               { "permitsrepost",     0 },
               { "bookings",          7 },
               { "bookingsrepost",    0 }
            };

public void SendNotification(string notificationType, string title, string message, object data)
{
    Log.Info(TAG, $"{nameof(SendNotification)} type {notificationType} title {title} message {message}");

    Intent intent = new Intent(AndroidApp.Context, typeof(MainActivity));
    intent.PutExtra("notification_type", notificationType);
    intent.PutExtra("summary", title);
    intent.PutExtra("details", message);
    intent.PutExtra("custom_data", data as string);
    intent.AddFlags(ActivityFlags.ClearTop);
    PendingIntent pendingIntent = null;

    var pendingIntentFlags = (Build.VERSION.SdkInt >= BuildVersionCodes.S)
        ? PendingIntentFlags.UpdateCurrent | PendingIntentFlags.Mutable
        : PendingIntentFlags.UpdateCurrent;

    pendingIntent = PendingIntent.GetActivity(AndroidApp.Context, pendingIntentId++, intent, pendingIntentFlags);

    notificationType = notificationType.ToLower();
    if (!knownNotificationTypes.TryGetValue(notificationType, out int channelId))
    {
        channelId = SHARED_CHANNEL_ID ;
        notificationType = SHARED_CHANNEL_NAME ;
    }

    NotificationCompat.Builder builder = new NotificationCompat.Builder(AndroidApp.Context, notificationType)
        .SetContentIntent(pendingIntent)
        .SetContentTitle(title)
        .SetContentText(message)
        .SetGroup("com.our.appname")
        .SetAutoCancel(true)
        .SetCategory(notificationType)
        .SetSmallIcon(Resource.Drawable.logo_mobile_round_icon)
        .SetDefaults((int)NotificationDefaults.Sound | (int)NotificationDefaults.Vibrate);

    Notification notification = builder.Build();

    _manager.Notify(channelId, notification);
}

This plugin intercepts this notification, but when trying to grab the data out of the notification (either in CrossFirebaseCloudMessaging.Current.NotificationReceived or CrossFirebaseCloudMessaging.Current.NotificationTapped), it is null (title and description are displayed fine).

Just wondering if I'm missing something obvious here.

Thanks!
