Hi all,

I am potentially building an app for a group of people who do some great volunteer work, and one of the big things they want in the app is push notifications so they can let people know when they're available/where they are.

The two big questions I have here are:
1: Regarding geolocations, is it possible to be far more specific, i.e. at an event/county (in the UK) or will I have to use topics?
2: What is the best way for a fairly technophobic group to utilise push notifications? I am worried that going through the FCM console on Firebase may be too technical for them.

Additional info:

I will be building this app in Flutter. I also don't actually know how to do push notifications correctly yet, I am currently learning that.
