Hi, I'm having a problem with the sfrotator when he has only one item and he clicks or tap to rotate the app crash

            SfRotator sfRotator = new SfRotator()
                HorizontalOptions = LayoutOptions.FillAndExpand,
                VerticalOptions = LayoutOptions.FillAndExpand,
                BindingContext = ViewModel,
                SelectedDotColor = Color.FromHex("#5E95AE"),
                DotsBorderColor = Color.FromHex("#5E95AE"),
                NavigationDirection = NavigationDirection.Horizontal,
                NavigationStripMode = NavigationStripMode.Dots,
                BackgroundColor = Color.Transparent,
                NavigationStripPosition = NavigationStripPosition.Bottom,
                ItemTemplate = itemTemplate,
                EnableSwiping = true,

            sfRotator.SetBinding(SfRotator.ItemsSourceProperty, "SelectedData");
            sfRotator.SetBinding(SfRotator.IsVisibleProperty, "IsNotBusy");

Hello I can play it if I leave the code you sent and change the parameter EnableSwiping to true the application stops when clicking or tapped

 rotator.ItemTemplate = itemTemplate;
            rotator.ItemsSource = ImageCollection;
            rotator.NavigationStripPosition = NavigationStripPosition.Bottom;
            rotator.NavigationStripMode = NavigationStripMode.Dots;
            rotator.NavigationDirection = NavigationDirection.Horizontal;
            rotator.IsVisible = true;
            rotator.EnableSwiping = true;
            this.Content = rotator;


          my solution will be and if someone else needs it

            sfRotator.SetBinding(SfRotator.EnableSwipingProperty, "IsEnableSwiping");

Hi Alejandro,

Thanks for the update.

We are glad that your issue has been resolved by setting the EnableSwiping property. We will make sure there is no errors when not setting the EnableSwiping in our future releases.

Please let us know if you have any concern.
