Here's the next feature that Xamarin offers to us: FlashLight

If you for some reason want that at some point your application will be able to turn on the flashlight, you can do it very easy.

As easy as that, just add this view to AppShell.xaml

In that file search this lines of code:

Okay, just test the app and check that you flashlight Turns On and Off.
