Xamarin forms monkey chat - xamarin

Question

I am using monkey chat in my mobile application(Xamrin forms based). While sending a message on IOS, on a real device, I have to click the send button 2 times. First time when I click, it minimizes the keyboard and 2nd time, it sends the message. Please suggest.
How do I send a message on one click?
Here is my send message function
namespace Budocode.ViewModels
{
public class MainChatViewModel : BaseViewModel
{
public ObservableRangeCollection Messages { get; }
ITwilioMessenger twilioMessenger;
string outgoingText = string.Empty;
public string OutGoingText
{
get { return outgoingText; }
set { SetProperty(ref outgoingText, value); }
}
public ICommand SendCommand { get; set; }
public ICommand LocationCommand { get; set; }
public MainChatViewModel()
{
// Initialize with default values
twilioMessenger = DependencyService.Get<ITwilioMessenger>();
Messages = new ObservableRangeCollection<ChatMessage>();
SendCommand = new Command(() =>
{
var message = new ChatMessage
{
Text = OutGoingText,
IsIncoming = false,
ProfileId = "profile" + GlobalSettingsDataSource.Current.SelectedProfileImageId + ".png",
MessageDateTime = DateTime.Now,
FromUser = GlobalSettingsDataSource.Current.SelectedProfile
};
if (string.IsNullOrWhiteSpace(OutGoingText))
return;
Messages.Add(message);
twilioMessenger?.SendMessage(message.Text, message.ProfileId, GlobalSettingsDataSource.Current.SelectedProfile);
OutGoingText = string.Empty;
});
LocationCommand = new Command(async () =>
{
try
{
var local = await CrossGeolocator.Current.GetPositionAsync(TimeSpan.FromSeconds(15));
var map = $"https://maps.googleapis.com/maps/api/staticmap?center={local.Latitude.ToString(CultureInfo.InvariantCulture)},{local.Longitude.ToString(CultureInfo.InvariantCulture)}&zoom=17&size=400x400&maptype=street&markers=color:red%7Clabel:%7C{local.Latitude.ToString(CultureInfo.InvariantCulture)},{local.Longitude.ToString(CultureInfo.InvariantCulture)}&key=";
var message = new ChatMessage
{
Text = "I am here",
AttachementUrl = map,
ProfileId = "profile" + GlobalSettingsDataSource.Current.SelectedProfileImageId + ".png",
IsIncoming = false,
MessageDateTime = DateTime.Now
};
Messages.Add(message);
twilioMessenger?.SendMessage("attach:" + message.AttachementUrl, message.ProfileId, GlobalSettingsDataSource.Current.SelectedProfile);
}
catch (Exception ex)
{
}
});
if (twilioMessenger == null)
return;
twilioMessenger.MessageAdded = (message) =>
{
//if (message.ProfileId == "Icon.png")
Device.BeginInvokeOnMainThread(() =>
{
if (message.FromUser != GlobalSettingsDataSource.Current.SelectedProfile)
{
message.IsIncoming = true;
}
else
{
message.IsIncoming = false;
}
Messages.Add(message);
});
};
}
public async void InitializeMock(string channelName)
{
try
{
var id = CrossDeviceInfo.Current.Id;
var userId = PersistantData.Current.UserAccount.Properties["user_id"];
HttpResponseMessage appResponse = CommonUtility.GetApiContent(
String.Format(ClientConfiguration.TwilioServiceChatHistory, id, GlobalSettingsDataSource.Current.SelectedProfile, channelName));
if (appResponse.IsSuccessStatusCode)
{
var chatContent = await appResponse.Content.ReadAsStringAsync();
List<ChatMessage> chatMsgs = JsonConvert.DeserializeObject<List<ChatMessage>>(chatContent);
Messages.ReplaceRange(chatMsgs);
}
}
catch
{
// ignore if there are any issues with twilio
}
}
}
}
