Flutter: cross-platform way to keep application running in the background

I'm trying to figure out a way to keep a Flutter application running even if it's not in focus. For instance have a countdown running and play an alarm sound/show notification on completion, no matter what's running in foreground. Can anyone point me in the right direction? Ideally something that works cross-platform.

I found this thread but it's almost 2 years old, so I'm thinking maybe there has been some development since then.

I have been trying to get my app to run in the background for quite a while now and i have finally found something that I thought might benefit others looking for a solution. The workmanager package has an unpublished branch that provides the ability to run for background code on ios upon closing the app. There seem to be little limitations except a time limit. find the pull request here:

and the branch here:

This looks like what you might want: https://medium.com/flutter-io/executing-dart-in-the-background-with-flutter-plugins-and-geofencing-2b3e40a1a124. It's a nice article on Medium describing how to run things in the background on both iOS and Android, especially using the most recent releases of Flutter.

The official documentation for Flutter in the background is at https://flutter.io/docs/development/packages-and-plugins/background-processes. The key is to run your code in an Isolate, because you won't have access to the GUI Isolate when you are in the background.
