Err, the whole block is inside a setState:

    setState(() {
      _markers.clear();
      for (final office in googleOffices.offices) {
        final marker = Marker(
          markerId: MarkerId(office.name),
          position: LatLng(office.lat, office.lng),
          infoWindow: InfoWindow(
            title: office.name,
            snippet: office.address,
          ),
        );
        _markers[office.name] = marker;
      }
    });
