You need to add your Google maps API key in your AndroidManifest.xml as per the Google maps flutter documentation. Since you said that you have generated the key.

Flutter web with Google Place Photos

Successfully using the Google Places API to display location photos in an iOS app. However, apparently this API isn't meant for client-side apps so when I deploy my Flutter app to the web I get a bunch CORS errors.
Unfortunately the docs for the Google Maps API don't speak to Flutter implementations though I found these two Flutter plugins that allow you to work with it:
google_maps_flutter
google_maps_flutter_web
The only issue is that they only provide examples of working with Google Maps and not getting locations photos. Does anyone have experience with these plugins or this issue?
Ideally I wouldn't have to use a plugin at all, I'd like to just be able to hit some endpoint like I can with the Places API, though the docs for this don't mention being able to do this.

How to drop a pin on Google Maps iPhone app via web link?

I used to just be able to have a link to a coordinate on Google Maps, like https://maps.google.com/maps?q=35.7491455078125,139.382995605469
but now that Apple kicked out the original Maps app, and Google has re-launched another one, links like that no longer drop a pin on the maps of iOS users.
Is there a way to drop a pin on a visitor's Google Maps app with the click of a link?
Sounds like the official Maps URLs would work for you. In your example, this should work (and across platforms, too!):
https://www.google.com/maps/search/?api=1&query=35.7491455078125,139.382995605469
You can read the full documentation at https://developers.google.com/maps/documentation/urls/guide
Replace http://maps.google.com with http://maps.apple.com, hopefully that works!
