Hello @Mohamed50 ,

Last time I tried I used the original map, but it didn't work.
Last week @cgaisl created a new map: the Mercator world map.

Using this map it should be possible but I havent tried it yet, there are some formulas for calculating this

Please see: https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames

You can for example add the map in a Stack widget and stack a Positioned Widget / CustomPainter on top that uses the coordinates to display your pin on top of the map.

Keep in mind that you use the exact dimensions as the map you are drawing.

I hope this helps you on your way, I plan to look into this myself in the future

Do you achieve something :) ? Very interesting point to be able to use LatLong on this kind of map.
Killer feature !

In the release 1.1.2 and higher there will be a build in function to add Markers to the map based on LAT LONG (special thanks to @EArminjon for the last pull request
