Each time the page is loaded the StarBehavior duplicates the number of stars and a wrong rating value about xamarin.forms-samples

I have the same issue. When I load with the rating initially. the rating values are correct (0-5). However, reloading the same page increases the rating values by the number of "new" selected stars. In looking at the behaviors collection, it is adding new behaviors to the list for the same group, resulting in 6+ behaviors.

After looking at it some, I added some math to correct the variation. Before the item.Rating is set, I do a loop to reduce by increments of 5 until it's the right range.

                while (position > 5)
                {
                    position = position - 5;
                }
                item.Rating = position;

After testing, this seems to resolve the issue.

@BryanSoltis , I tried your solution, but i could see that the controls will still be there if the rating is reseted.

I did following and it works.

StarBehavior.cs added following:
public static void ResetStarBinding() { starGroups = new Dictionary<string, List<StarBehavior>>(); }
Then before i load the page i call "StarBehavior.ResetStarBinding();"

This seems to resolve the problem and not adding more controls than there is needed, in my case 5 :)

I know this is old, but issue is still there, i wanted to share my solution with you all :)
