🐛 [firebase_messaging] When tapping app icon with pending notification, data is never received by the app

[jlubeck]

Bug report

Describe the bug
There was a ticket for this already here: #553 but it was closed without been fixed.

When you get a new notification on Android, you get it both to the notification center and also the icon gets a badge with a number.

It is expected that when you tap on either the notification or the icon itself, to get the notification's data. You currently don't get anything when tapping on the icon, only when tapping on the notification.

Furthermore, the notification is not cleared when tapping on the icon.

That piece itself can be solved by changing the MainActivity class to add this on onCreate :

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancelAll();

This clears the notification, but now you lost the notification data forever.

Additional context

Besides the main issue, it would also be nice to be able to clear notifications within Flutter, and not having to mess with native Android code.
