Can a flutter app run code on receiving a push notification while Not Running

Question

I have push notifications working and have both a data and notification part in them. In the data part is a tag that tells the app what updates are available for the user.

The problem is that I would like the app to fetch those updates even if the user does not tap on the notification.

With other apps, eg Whatsapp, a notification is shown. Without tapping this notification, and even when the app is not running, the app downloads the data. For example if the user switches to flight mode right after receiving the notification and then opens whatsapp, the message and/or picture is there, already downloaded and displayed in the app.

So the question is how to get an app written in Flutter to download something in response to getting a push notification, regardless of whether the app is in the foreground, background, or not running.

Checkout isolate mentioned in Flutter background processes with a link to Medium Executing Dart in the Background with Flutter Plugins and Geofencing

Checking with GitHub issue Flutter should provide an abstraction for background execution and issue comments/references after that you may find some other examples. Bottom line is people need more examples.
