How to show the current location in the .NET MAUI Maps (SfMaps)?

In the Syncfusion .NET MAUI Maps control, you can use the Geolocation.GetLocationAsync() method to show the current location in the SfMaps through the following steps.

Step 1: Add the SfMaps control and initialize the MapTileLayer with OSM type, as shown in the following code sample.

XAML:

<map:SfMaps>
   <map:SfMaps.Layer>
   	<map:MapTileLayer x:Name="tileLayer"
                          UrlTemplate="https://tile.openstreetmap.org/{z}/{x}/{y}.png">
   	</map:MapTileLayer>
   </map:SfMaps.Layer>
</map:SfMaps> 

Step 2: Add a custom marker in the MarkerTemplate property to show the pin image as marker.

XAML:

<map:MapTileLayer.MarkerTemplate>
   <DataTemplate >
   	<Image Source="pin.png"
   	       Scale="1"
   	       Aspect="AspectFit"
   	       HorizontalOptions="StartAndExpand"
   	       VerticalOptions="Center"
   	       HeightRequest="35"
   	       WidthRequest="25" />
   </DataTemplate>
</map:MapTileLayer.MarkerTemplate> 

Step 3: Get the current location from the Geolocation.GetLocationAsync method and add the obtained latitude and longitude values to the MapTileLayer’s Center and Marker properties as shown in the following code sample.

XAML:

<map:MapTileLayer.Markers>
   <map:MapMarkerCollection>
   	<map:MapMarker x:Name="marker"  />
   </map:MapMarkerCollection>
</map:MapTileLayer.Markers> 

C#:

private async void GetLocation()
{
   Location location = await Geolocation.GetLocationAsync(new GeolocationRequest
   {
   	DesiredAccuracy = GeolocationAccuracy.High,
   	Timeout = TimeSpan.FromSeconds(30)
   });

   if (location != null)
   {
   	tileLayer.Center = new MapLatLng(location.Latitude, location.Longitude);

   	marker.Latitude = location.Latitude;
   	marker.Longitude = location.Longitude;
   }
}

Step 4: Display the map with a specific distance around the current location by specifying the Radius and DistanceType properties of the MapTileLayer.

XAML:

<map:MapTileLayer x:Name="tileLayer"
   	          UrlTemplate="https://tile.openstreetmap.org/{z}/{x}/{y}.png"
   	          Radius="5"
   	          DistanceType="Kilometer">

</map:MapTileLayer> 

Step 5: In order to access Geolocation functionality, a platform-specific setup must be configured.

Android: Open the Platforms/Android/AndroidManifest.xml file and add the following permission tags.

XML:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 

Windows: Open the Platforms/Windows/Package.appxmanifest, go to capabilities, and enable the location.

View the sample on GitHub.
