Dark mode on Xamarin

Dark mode darkens background colours and provides a more comfortable viewing experience in low light. This is essential for many visually impaired people since a light background colour can be painful or even impossible to look at for an extended period of time. But also people who have problems with their concentration, for example due to a brain disorder, benefit greatly from dark mode.

With Xamarin, you can detect dark mode by checking if the RequestedTheme property equals OSAppTheme.Dark.

In XAML you can use AppThemeBinding to define different resources for dark mode.

using Xamarin.Essentials;

OSAppTheme theme = Application.Current.RequestedTheme;
if (theme == OSAppTheme.Dark) {
    // Dark mode
