Import points onto a map with a database

Good morning,

I want to display points on a Google Maps map. I inserted my database with a LatLng column (photo 1). I then followed this documentation: https://docs.flutterflow.io/widgets-and-components/widgets/base-elements/googlemap#adding-markers

However, despite all the criteria provided (photo 2), I cannot make the points appear on the map. (photo 3)

When I select in Marker L

atLng: Num markers: Single, I can select in the Global Properties part: Current Device Location and when I select multiple, I no longer have

access to this option.

Thanks for your help,

Nicolas
