Xamarin.Forms code runs on multiple platforms - each of which has its own filesystem. This means that reading and writing files is most easily done using the native file APIs on each platform. Alternatively, embedded resources are a simpler solution to distribute data files with an app.

Xamarin.Essentials

Xamarin.Essentials plugin provides 20+ cross-platform APIs for  mobile application development. Xamarin.Essentials API works with all Xamarin.Forms, Xamarin.Android, Xamarin.iOS, or UWP application that can be accessed from shared code. When we are developing Xamarin with Android, iOS and UWP apps but now Xamarin.Essentials overcome the problem, developers can access every native platform API using C#. This plugin provides many APIs so initially, there is no need of more plugins for Xamarin. Xamarin.Essentials plugin impacts your app's minimum size.

Platform Support

Xamarin.Essentials supports platforms and operating systems

Platform Version

Start by creating a new Xamarin.Forms project.  you’ll learn more by going through the steps yourself.
Choose the Xamarin.Forms App Project type under Cross-platform/App in the New Project dialog.

Name your app, select “Use Portable Class Library” for shared code, and target both Android and iOS.

You probably want your project and solution to use the same name as your app. Put it in your preferred folder for projects and click Create.

using Xamarin.Essentials;
namespace XamarinEssentials
{
 public partial class MainPage : ContentPage
 {
  public MainPage()
  {
   InitializeComponent();

            var tapGestureRecognizer = new TapGestureRecognizer();
            tapGestureRecognizer.Tapped += async (s, e) => {
                Clipboard.SetText(lblCopy.Text);
                if (Clipboard.HasText)
                {
                    var text = await Clipboard.GetTextAsync();
                    DisplayAlert("Success",string.Format("Your copied text is({0})",text),"OK");
                }
            };
            lblCopy.GestureRecognizers.Add(tapGestureRecognizer);

  }
 }
}

Click the play button to try it out.
