Can I adjust the Firestore Listener Frequency?

I have a Flutter & Firebase app that provides users with price updates on the dashboard on the main screen. It does this with a Firestore Snapshot Listener, but my read count is flying through the roof (I'm at 203 reads and just 1 device is connected)... This info will only change once a month, and it really doesn't need to keep checking for updates at all times.

Is there a way to setup the listener so that it checks less frequently for updates? Or perhaps, can I setup a Firebase In-App Messaging system with which I send the price out and the app just saves and displays it?

Or is there any efficient solutions?

Since the Listener (which you do not show, so we can't even help you there) ONLY triggers when there is an update to the documents (NOT on a schedule) something is updating the collection you are listening to. 203 is not particularly high over a few days - how long has your app been running? Have you been restarting the app frequently? Most Listeners will give you a result at least once when you initialize them - i.e. when you start the app. There is no "long-term global memory" like that.

A listener will always receive updates as soon as they becomes available. This can't be configured. If you want a different update frequency, you should instead schedule that yourself within the app, and use get() to poll the database as often as you need. You can also use FCM on your backend to push updates to the app, if that works for your case.
