Marker Layer

You can add markers to maps to display specific points to users using MarkerLayer().

FlutterMap(
    options: MapOptions(),
    children: [
        MarkerLayer(
            markers: [
                Marker(
                  point: LatLng(30, 40),
                  width: 80,
                  height: 80,
                  builder: (context) => FlutterLogo(),
                ),
            ],
        ),
    ],
),

Excessive use of markers or use of complex markers will create performance issues and lag/'jank' as the user interacts with the map. See for more information.

If you need to use a large number of markers, an existing community maintained plugin (flutter_map_marker_cluster) might help.

Markers (markers)

As you can see MarkerLayerOptions() accepts list of Markers which determines render widget, position and transformation details like size and rotation.

Property	Type	Defaults	Description
point	LatLng	required	Marker position on map
builder	WidgetBuilder	required	Builder used to render marker
width	double	30	Marker width
height	double	30	Marker height
rotate	bool?	false*	If true, marker will be counter rotated to the map rotation
rotateOrigin	Offset?		The origin of the marker in which to apply the matrix
rotateAlignment	AlignmentGeometry?		The alignment of the origin, relative to the size of the box
anchorPos	AnchorPos?		Point of the marker which will correspond to marker's location
