MapPolygonLayer transparency on hover

[Will Roxby]

Hi,

I'm currently experiencing an issue with the `MapPolygonLayer`. In our use-case we wish to have a sublayer showing polygons over the map. The polygons show successfully but `onHover` the transparency we have set is overridden causing our map be hidden.

We wish to have the ability to show polygons and when the mouse triggers the hover action for our `Color` set to not change.

Are there any work arounds in the meantime and would it be possible to have the hover action optional?

Please refer to the video attached.

Thanks,

Will

Hi Will,

Greetings from Syncfusion.

We have checked your query, and we would like to let you know that you can customize the shape hover color in the maps widget by wrapping the SfMaps widget inside the SfMapsTheme and setting the shapeHoverColor for the SfMaps widget as per your requirement.

For your case, we suggest setting the shapeHoverColor to Colors.Transparent so that when hovering on the polygons, its transparency will not change. Please check the code snippet below for reference.

SfMapsTheme(

        data: SfMapsThemeData(

           shapeHoverColor: Colors.transparent,

           shapeHoverStrokeColor: Colors. transparent,

        ),

        child: SfMaps(

          layers: <MapLayer>[

            MapShapeLayer(

              source: dataSource,

            ),

          ],

        )

Also appended the user guide documentation for customizing the hover color in the maps below for your reference.
