SfAutoComplete crashes the app when clear button clicked (Android)

[Astrit Bako]

I'm using SfAutoComplete (VS 2017, Xamarin Forms) to select a city name from a list of cities, everything works fine but when I click the clear x button (on Android) the application crashes 

and it goes on break mode...any ideas as to what is causing this?

Hi, thanks for the reply below is the code I'm trying to implement, when deleting letters using delete from keyboard works ok, but if I click on x clear button inside the SfAutoComplete  it crashes the app.

public async void autocomplete_SelectionChanged(object sender,Syncfusion.SfAutoComplete.XForms.SelectionChangedEventArgs e)
        {
          
            if (!string.IsNullOrWhiteSpace(autoComplete.SelectedValue.ToString()))
            {
              
                city = autoComplete.SelectedValue.ToString();
              
                if (!string.IsNullOrEmpty(city))
                {
                    com = await dal.GetCompanyBySpecialityCity(city, speciality);
                }
              
                if (com!=null && com.Count > 0 && city!=null)
                {
                    lst.ItemsSource = com;
                }
                else
                {
                    await DisplayAlert("List", "No items found matching your criteria", "Ok");
                    lst.ItemsSource = null;
                    autoComplete.Clear();
                }
             

            }   
          
        },

Hi Astrit,

Thank you for your update.

We have able to reproduce the reported issue in SfAutoComplete. While clicking the Clear Button in SfAutoComplete control the SelectedItem and SelectedValue will become null. So while you have checked the SelectedValue and converted the SelectedValue to string which is null and it throws null exception and app crash occurs. We have modified your SelectionChangedEvent and attached the sample for your reference.

Please let me know if the issue resolved your side.
