I need a message on the Exit Button (I will use the Navigation.PopAsync()) next to what I did but that works (this one doesn’t work):

//Botão Sair
void BtnSair_Clicked(object sender, EventArgs e)
{
   var result = DisplayAlert("Alerta", "Deseja realmente sair?", "Sim", "Não");
   if (result) {Navigation.PopAsync();}  
}

As for some it may be useful I managed to solve as follows:

private async Task BtnSair_Clicked(object sender, EventArgs e)
{
  var result = await DisplayAlert("Alerta", "Deseja realmente sair?", "Sim", "Não");

  if (result)
  {
    await Navigation.PopAsync();
  }
}

I noticed that Displayalert returns Task and the variable expected only bool, then in the call of the button I used private async Task and then await where you will have to wait for return.
