如何在Xamarin表单中实现标记集群( Google地图)

<maps:Map MapType="Street" />

var clusteredMap = new ClusteredMap();
map.Map = clusteredMap;

var clusterOptions = new ClusterOptions
{
    MinimumClusterSize = 2,
    ClusterShape = ClusterShape.Circle
};

var clusteredMapRenderer = new ClusteredMapRenderer();
clusteredMap.Renderer = clusteredMapRenderer;
clusteredMapRenderer.ClusterOptions = clusterOptions;

var pins = new List<Pin>
{
    new Pin
    {
        Position = new Position(37.79752, -122.40183),
        Label = "Marker 1",
        Icon = BitmapDescriptorFactory.DefaultMarker(BitmapDescriptorFactory.HueRed)
    },
    new Pin
    {
        Position = new Position(37.79752, -122.40183),
        Label = "Marker 2",
        Icon = BitmapDescriptorFactory.DefaultMarker(BitmapDescriptorFactory.HueBlue)
    },
    // Add more pins...
};

clusteredMap.ItemsSource = pins;
