cancelNotification on last grouped notification leaves empty group

[yotam-nots]

Hey,

On Android, I've noticed that calling cancelNotification on the last notification in a group leaves an empty group summary notification.
Clicking on the last notification does get clear the group summary as expected.

Code that reproduces the issue:

const androidChannelId = await notifee.createChannel({
  id: "default",
  name: "Default Channel",
  sound: "default",
  importance: Importance.HIGH,
});
await notifee.displayNotification({
  title: "group",
  id: "group-id",
  subtitle: "subtitle",
  android: {
    channelId: androidChannelId,
    groupSummary: true,
    groupId: "group-id",
    smallIcon: "notification_icon",
    color: "#ffcc11",
    groupAlertBehavior: AndroidGroupAlertBehavior.CHILDREN,
    pressAction: {
      launchActivity: "default",
      id: "default",
    },
  },
});
await notifee.displayNotification({
  id: "notification-id",
  title: "title",
  subtitle: "hello",
  body: "body",
  android: {
    importance: Importance.HIGH,
    channelId: androidChannelId,
    color: "#ffcc11",
    smallIcon: "notification_icon",
    groupId: "group-id",
  },
});
await notifee.cancelNotification("notification-id");

It should be possible to track how many notifications are displayed in a group using the DISMISSED events, and when the group gets to 1, delete the group via cancelNotification(groupId) and redisplay the last notification.

@helenaford that could work, but I feel like it could be nice if it was taken care of on the library level. Seems like a lot of logic, and that anyone who uses groups would need to reimplement

@yotam-nots It only occurs if you are using groups with cancelNotification. Not sure how much this happens, maybe it's common feature... something we can look into.

thanks!

possibly related: maybe the (missing?) tag functionality could help here?

Please reopen if this is still an issue.
