Xamarin.Forms how to add app rating on Android and iOS?

Which is the best/simplest option to add app rating on a Xamarin.Forms application, the default stars form directly connected to the Play Store or App Store?

The Store Review Nuget plugin has been updated to v3 recently thanks to the new (August 2020) Android native Play Core library so that it displays an In-App Review on both iOS & Android using just one line of code:

await CrossStoreReview.Current.RequestReview(false);

So now, you don't have to worry about opening the url of the app in the external store or a web view, it will be shown directly in the app. You can see more details on this Microsoft Blog

Just remember to add the necessary code in the proguard file mentioned in the README of the Nuget's GitHub repository

Edit: I've created an nuget package for this, you can download from Here or check the GitHub repo.

On Android you must open the PlayStore in order to rate the app, on iOS you can do it inside the app, but only from iOS 10 onwards.

You must implement native methods and use it via dependecy service.

Interface

public interface IAppRating
{
    void RateApp();
}

Android

public class AppRatiing : IAppRating
{
    public void RateApp()
    {
        var activity = Android.App.Application.Context;
        var url = $"market://details?id={(activity as Context)?.PackageName}";

        try
        {
            activity.PackageManager.GetPackageInfo("com.android.vending", PackageInfoFlags.Activities);
            Intent intent = new Intent(Intent.ActionView, Uri.Parse(url));

            activity.StartActivity(intent);
        }
        catch (PackageManager.NameNotFoundException ex)
        {
            // this won't happen. But catching just in case the user has downloaded the app without having Google Play installed.

            Console.WriteLine(ex.Message);
        }
        catch (ActivityNotFoundException)
        {
            // if Google Play fails to load, open the App link on the browser 

            var playStoreUrl = "https://play.google.com/store/apps/details?id=com.yourapplicationpackagename"; //Add here the url of your application on the store

            var browserIntent = new Intent(Intent.ActionView, Uri.Parse(playStoreUrl));
            browserIntent.AddFlags(ActivityFlags.NewTask | ActivityFlags.ResetTaskIfNeeded);

            activity.StartActivity(browserIntent);
        }
    }
}

iOS

public class AppRating : IAppRating
{
    public void RateApp()
    {
        if (UIDevice.CurrentDevice.CheckSystemVersion(10, 3))
            SKStoreReviewController.RequestReview();
        else
        {
            var storeUrl = "itms-apps://itunes.apple.com/app/YourAppId";
            var url = storeUrl + "?action=write-review";

            try
            {
                UIApplication.SharedApplication.OpenUrl(new NSUrl(url));
            }
            catch(Exception ex)
            {
                // Here you could show an alert to the user telling that App Store was unable to launch

                Console.WriteLine(ex.Message);
            }
        }
    }
}

On Android (tested in 9.0) I have to add this flag at FabriBertani´s solution:

activity.StartActivity(intent);
