    {
        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)

CodePudding user response：

you can get the value of the selected row from the binding context

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

        public ListDetailPageViewModel()
        {
            Lanches = new ObservableCollection<ListModel>();

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