Hello, we have a legend view in our C# app that uses the Esri.ArcGISRuntime.Toolkit.Xamarin.Forms.LayerLegend class. Everything is working fine except the text for the legend is black, which becomes invisible when using the app in night mode. How do we set the font color of the LayerLegend controls? I would have expected there to be a property like FontColor but there isn't one.
