推荐答案

这个功能现在在 google_maps_flutter 包中可用:

This functionality is now available in the google_maps_flutter package:

https://pub.dev/documentation/google_maps_flutter_platform_interface/latest/google_maps_flutter_platform_interface/Circle-class.html

部分示例:

Set<Circle> circles = Set.from([Circle(
    circleId: CircleId(id),
    center: LatLng(latitude, longitude),
    radius: 4000,
)]);

GoogleMap(
    mapType: MapType.normal,
    myLocationEnabled: true,
    myLocationButtonEnabled: true,
    initialCameraPosition: initialMapLocation,
    onMapCreated: (GoogleMapController controller) {
      _controller.complete(controller);
    },
    onCameraMove: null,
    circles: circles,
  );
