According to the official documentation Display icons on menu items, you could set the
IconImageSource property of the
MenuFlyoutItem to set the icon.
However, after code testing, whether
IconImageSource is set in the Click event or data binding is set on
IconImageSource using MVVM, the view cannot display the icon when selected.
Therefore, it is more recommended that you publish this issue to the GitHub repository to make the development team aware of this issue.
