Making a button visible after its past the current time using Xamarin.Forms - xamarin

Question

I have a list-view which displays the current user medication schedule it currently sorts the list by the next due date and any medications that are past the current time are moved to the bottom of the list.
I was looking to make the medications that are past the current time to have a 'Tomorrow' button visible to it. Is this possible to do?
Currently this is how I am populating my listview:
/// <summary>
/// Gets User Medication list
/// </summary>
/// <returns>The user meds.</returns>
async public Task GetUserMedsOverdue()
{
MedicationListOverdue.ItemsSource = null;
UserMedTimesOverdue.Clear(); //Clears the list before calling API (prevents duplication)
main.Children.Add(MedicationListOverdue);
main.Children.Remove(NoMeds);
if (!CrossConnectivity.Current.IsConnected)
{
main.Children.Remove(MedicationListOverdue);
main.Children.Add(NoMeds);
NoMeds.Text = "No Internet Connection - Please check your connection";
NoMeds.Margin = new Thickness(35, 35, 20, 20);
BusyIndicator.IsRunning = false;
}
else
{
BusyIndicator.IsRunning = true;
//var usermed = await medicinemanager.CurrentClient.InvokeApiAsync<IEnumerable<usermedication>>("getusermednamejoin?userid=" + Helpers.Settings.UserKey + "", System.Net.Http.HttpMethod.Get, null);
try
{
var usermeddosagetimeoverdue = await medicinemanager.CurrentClient.InvokeApiAsync("getUserMedDosageTimeOverdue?userid=" + Helpers.Settings.UserKey, null, HttpMethod.Get, await App.LoadAPIKeyAsync(), null);
var responseContentoverdue = await usermeddosagetimeoverdue.Content.ReadAsStringAsync();
var useroverdue = JsonConvert.DeserializeObject<ObservableCollection<UserMedDosagePayLoadOverdue>>(responseContentoverdue);
//var usermeddosagetime = await medicinemanager.CurrentClient.InvokeApiAsync<IEnumerable<UserMedDosagePayLoad>>("getusermeddosagetime?userid=" + Helpers.Settings.UserKey + "", HttpMethod.Get, API, System.Threading.CancellationToken.None);
//null, System.Net.Http.HttpMethod.Get, API, System.Threading.CancellationToken.None);
Debug.WriteLine("UserMedDosageTime" + usermeddosagetimeoverdue);
foreach (UserMedDosagePayLoadOverdue item in useroverdue)
{
UserMedTimesOverdue.Add(item);
}
}
catch (Exception ex)
{
Debug.WriteLine(ex.ToString());
}
FindNextDue(UserMedTimes);
//Get the List of meds the user is on
//UserMedList = await usermedicationmanager.getUserMedication();
//foreach (usermedication item in usermed)
//{
// if (item.IsActive != false)
// {
// UserMedList.Add(item);
// }
//}
if (UserMedTimes.Count != 0)
{
MedicationListOverdue.ItemsSource = UserMedTimesOverdue;
