I need help to integrate leaflet maps in flutter. The project I'm working on requires showing custom markers, animations, routes and drawings on the map. But I can't find any documentation or tutorials explaining this in flutter.
You can use flutter_map package for that. That's one of two most widely used maps packages (next to google_maps_flutter, which is obviously only for Google Maps).

It features all things that you need AFAIR.
