   </ContentPage.BindingContext>
<StackLayout>
    <buttons:SfRadioGroup x:Name="radioGroup" 
  BindableLayout.ItemsSource="{Binding Cities}">
        <BindableLayout.ItemTemplate>
            <DataTemplate>
                <buttons:SfRadioButton 
                  Text="{Binding CityName}" />
            </DataTemplate>
        </BindableLayout.ItemTemplate>
    </buttons:SfRadioGroup>
    <Button WidthRequest="200" Text="Get Checked RadioButton" Clicked="Button_Clicked"/>
</StackLayout>

C#:

public partial class MainPage : ContentPage
{
    
    public MainPage()
    {
        InitializeComponent();
    }

    private void Button_Clicked(object sender, EventArgs e)
    {
        var selectedRadioButton = radioGroup.CheckedItem.Text;
        App.Current.MainPage.DisplayAlert("Hello", "Selected " + selectedRadioButton, "Ok");
    }
}

public class City
{
    public string CityName { get; set; }

}

public class ViewModel
{
    private ObservableCollection<city> cities;

    public ObservableCollection<city> Cities
    {
        get { return cities; }
        set { cities = value; }
    }
    public ViewModel()
    {
        Cities = new ObservableCollection<city>();
        Cities.Add(new City() { CityName = "Tokyo" });
        Cities.Add(new City() { CityName = "Paris" });
        Cities.Add(new City() { CityName = "New York City" });
