You can use a ViewModel and bind a property to your label in xaml and call a function from your page constructor to update it.

Or you can try this:

    public Data(String data)
    {
        InitializeComponent();

        Task.Run(async() => await GetinfoAsync());
    }

    public async Task GetinfoAsync()
    {

        var responseString = await 
        client.GetStringAsync("https://reqres.in/api/users/2");
        show = responseString;
       // DisplayAlert("text", responseString, "ok");

       Device.BeginInvokeOnMainThread(()=>{
          displaylabel.Text = show;
       });
    }
