XAML

Define the DataTemplates for LeftSwipeTemplate and RightSwipeTemplate in Application.Resources.

<Application xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="ListViewXamarin.App">
    <Application.Resources>
        <ResourceDictionary>
            <DataTemplate x:Name="RightSwipeTemplate" x:Key="RightSwipeTemplate">
                <Grid BackgroundColor="#009EDA" HorizontalOptions="Fill" VerticalOptions="Fill">
                    <Label Text="Right Swipe template" Padding="10" TextColor="White" HorizontalOptions="Center" VerticalOptions="Center"/>
                </Grid>
            </DataTemplate>
 
            <DataTemplate x:Name="LeftSwipeTemplate" x:Key="LeftSwipeTemplate">
                <Grid BackgroundColor="#DC595F" HorizontalOptions="Fill" VerticalOptions="Fill">
                    <Label Text="Left Swipe template" Padding="10" TextColor="White" HorizontalOptions="Center" VerticalOptions="Center"/>
                </Grid>
            </DataTemplate>
        </ResourceDictionary>
    </Application.Resources>
</Application>

C#

Change the FlowDirection property in the Button Command execute method.

namespace ListViewXamarin
{
    public class ContactsViewModel : INotifyPropertyChanged
    {
        private FlowDirection listViewFlowDirection;
        public FlowDirection ListViewFlowDirection
        {
            get { return listViewFlowDirection; }
            set
            {
                listViewFlowDirection = value;
                this.RaisedOnPropertyChanged("ListViewFlowDirection");
            }
        }
 
        public Command ButtonCommand { get; set; }
        
        public ContactsViewModel()
        {
            ButtonCommand = new Command(OnButtonClicked);
        }
        
        private void OnButtonClicked(object obj)
        {
            if (this.ListViewFlowDirection == FlowDirection.RightToLeft)
                this.ListViewFlowDirection = FlowDirection.LeftToRight;
            else
                this.ListViewFlowDirection = FlowDirection.RightToLeft;
        }
    }
}

C#

Converter to return the DataTemplate for LeftSwipeTemplate and RightSwipeTemplate based on the FlowDirection.

namespace ListViewXamarin
{
    public class SwipeTemplateConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            if ((string)parameter == "RightSwipeTemplate")
            {
                if ((FlowDirection)value == FlowDirection.RightToLeft)
                    return App.Current.Resources["LeftSwipeTemplate"] as DataTemplate; 
                else
                    return App.Current.Resources["RightSwipeTemplate"] as DataTemplate;
            }
            else
            {
                if ((FlowDirection)value == FlowDirection.RightToLeft)
                    return App.Current.Resources["RightSwipeTemplate"] as DataTemplate;
                else
                    return App.Current.Resources["LeftSwipeTemplate"] as DataTemplate;
            }
        }
 
        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }
}
