Can we use CometChat, if so Can we customize the cometchat plugin UI?
Suggest some best one to one chat plugin.
There's no best one. I think you should find out which one is the most suitable for you.
And there're so many libraries you could choose i.e.https://forums.xamarin.com/discussion/155769/please-provide-me-source-to-create-chat-application
In the above link they had mentioned a solution with signalR, can we make video call and voice calls with signalR?
@Swarupa2398 You can have a try. There're many samples on the internet.
