I use MapView.FlashFeature(SelectionSet) to flash some features. But when flash, it display a cyan overlay to my feature. How to remove this? Or another way to flash/blink features?
I removed FeatureLayer's SelectionColor of FeatureLayer, set UseSelectionSymbol to false. In SelectionOptions i set SelectionColor to NoColor, set ShowSelectionGraphic to false. But the cyan overlay still display when flash.
