Prevent capturing the video player

Hi there

Ive read its possible prevent screen capturing in android and ios (Didnt find a solution for uwp yet)
[Here](https://stackoverflow.com/questions/28606689/how-to-prevent-screen-capture-in-android)
And [here](https://stackoverflow.com/questions/46336520/ios-11-screen-record-disable-video-recording)

The question is How do i implement this flag secure in xamarin forms

getWindow().setFlags(LayoutParams.FLAG_SECURE, LayoutParams.FLAG_SECURE);

Thanks

Start by reviewing the Xamarin Forms integration and the Android, iOS, and UWP platform layers mentioned in the issue, with the Android FLAG_SECURE example as the initial reference. Determine which platforms can prevent capture and what API surface should expose the behavior; done means the requested video-player capture prevention works consistently where supported.
