Greetings from Syncfusion.
We don't have support for the offline map by using the mbtiles file in SfMaps. We currently have support for OSM (default tile layer) and Bing map. This map will be downloaded from the online server and the tiles will be stored in the application cache. Next time, it will be referred from cache whether you are in online or offline.
