Circle Layer

We're writing this documentation page now! Please hold tight for now, and refer to older documentation or look in the API Reference.

You can add circle polygons to maps to users using CircleLayer().

FlutterMap(
    options: MapOptions(),
    children: [
        CircleLayer(
            circles: [],
        ),
    ],
),

Due to the nature of the Earth being a sphere, drawing lines perfectly requires large amounts of difficult maths that may not behave correctly when given certain edge-cases.

Avoid creating large polygons, or polygons that cross the edges of the map, as this may create undesired results.

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