Roadmap

[andersonvieiragomeslopes]

What is the roadmap of features you intend to implement in the plugin?

I would like to contribute to the project, but first I need to know which direction you want to take with the plugin.

[Alex-Dobrynin]

Hi. What do you mean under "direction". This is open source library, everybody can contribute to it. This will be absoultely crossplatform, absolutely flexible, abslolutely MVVM, absolutely public/protected to be editable for your needs.
There is another one Google maps lib written by mr onion, but it just bad port of xamarin forms lib to maui. In this lib i want to completely redesign everything.
It is already completed, just adding Sample project for each individual feature this lib supports. you can download repo and try simple sample for pins and circles. for what i see, i need implementation for clusters. but for now i need to finish sample and release nuget

[Alex-Dobrynin]

There is new version of the lib v2. added heat maps and clusters. docs updated.

Next will be kml and geojson

Wowww thanks for you hard work for this.

Now I see that I can migrate from component to this one which has a better approach and support for all other items in the same component!!!

Hey @Alex-Dobrynin

What's your opinion about this? Technically posible or imposible with cluster?

I was considering this, but I haven't come to a final conclusion on the topic.

[Alex-Dobrynin]

I think it can be done by subclassing GoogleMap control and overriding this method:

protected virtual async Task<IEnumerable<Cluster>?> GetClusters(CancellationToken token = default)
{
    var algo = ScreenBasedAlgorithm!;
    algo.OnCameraChange(CameraPosition);

    if (Pins?.Count() is null or 0)
    {
        algo.ClearItems();
        return null;
    }

    try
    {
        return await Task.Run(() =>
        {
            algo.ClearItems();
            algo.AddItems(Pins);
            return algo.GetClusters(CameraPosition.Zoom, token);
        }, token);
    }
    catch (Exception ex)
    {
        return Enumerable.Empty<Cluster>();
    }
}

Since cluster - is collection of pins, you can iterate through all clusters and through all items of each cluster, find your particular pin and move it to the separate cluster with amount of items == 1 and return new collection from this method.

Also, you can create AttachedProperty for your pin and attach it to the needed pin like next:

<gm:Pin PinAttached.ShouldBeClusterized="False" />

and then use it in the code:

var clusterize = PinAttached.GetShouldBeClusterized(pin);

Good, but.. this is not very clear to me

[andersonvieiragomeslopes]

I imagine using a bool property on Pin or cluster class: IsClusteredPinIgnore = true/false.

[Alex-Dobrynin]

Im sorry, but i will not add this property. because this is very rare case when you dont need to cluster particular pin. I have already provided you a solution how to achieve it. all you need to do is two things: create boolean attached property and override that method and filter by that property. Also, if it was so needed case, this would be already implemented by the google in their utility sdk. but, unfortunately for you, this is not the case

[andersonvieiragomeslopes]

Yes, you're right, it's a very rare and unique case of mine.

I will analyze the solution you proposed more carefully, thank you.

[Alex-Dobrynin]

Added KML and GeoJSON features. so thats all. it has all the features google sdk provides us. new v3 is already available
