與系結文本xamarin表單共享tex

我不能在這里共享系結名稱是代碼

我不能呼叫系結名稱，我只是共享一個字串，請有人幫助我如何呼叫系結名稱？

                            </Grid.ColumnDefinitions>

                            <Label  x:Name="Nome666"
                                                       Grid.Column="1"
                                   Text="{Binding Nome}"
                                   FontSize="Medium"
                                   TextColor="White"
                                   VerticalOptions="End"/>
                          

                            <Button x:Name="Button666"
                                Text="Compartilhar Texto"
                                    Clicked="ButtonClicked"
                                    />

                        </Grid>
                    </ViewCell>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>
    </ContentPage.Content>
</ContentPage>

這是cs中的代碼

using System;

using Xamarin.Forms;
using Xamarin.Forms.Xaml;
using XF_ListViewDetails_MVVM.ViewModels;
using Xamarin.Essentials;
using System.Threading.Tasks;


namespace XF_ListViewDetails_MVVM.Views
{
    [XamlCompilation(XamlCompilationOptions.Compile)]
    public partial class ListDetailPage : ContentPage
    {
        public ListDetailPage(string Nome, string Ingredientes, string fonte)
        {
            InitializeComponent();
            BindingContext = new ListDetailPageViewModel();
        }

          async void ButtonClicked(object sender, System.EventArgs args)
        {

         await CompartilharTexto(Nome666.Text);


        }

             public async Task CompartilharTexto(string texto)

       {

          await Share.RequestAsync(new ShareTextRequest

       {
        Text = texto,
        Title = "Compartilhando Texto"


         });
 

    }
        }}

代碼不共享我需要知道如何呼叫主頁上的系結名稱，它不會在模型中運行僅在主頁上

您可以從系結背景關系中獲取所選行的值

async void ButtonClicked(object sender, System.EventArgs args)
{
   var btn = (Button)sender;  
   var item = (YourClassNameGoesHere)btn.BindingContext;
   await CompartilharTexto(item.Nome);
}

namespace XF_ListViewDetails_MVVM.Models
{
    public class ListModel
    {
        public string Nome { get; set; }

        
        public string Detalhe { get; set; }
        public string Imagem { get; set; }
        public string Ingredientes { get; set; }
    }
}

public class ListDetailPageViewModel
{
    public ObservableCollection<ListModel> Lanches { get; set; }
    public ListDetailPageViewModel()
    {
        Lanches = new ObservableCollection<ListModel>();

        Lanches.Add(new ListModel
        {
            Nome = "Cheese Burger Completo",
        });

        Lanches.Add(new ListModel
        {
            Nome = "Cheese Salada Completo",
        });

        Lanches.Add(new ListModel
        {
            Nome = "Cheese Burger com Ovo ",
        });
    }
}
}
