I'm developing a flutter app with a feature where users can chat in real time and make audio/video calls. can I use Twilio's APIs for them. It seems Twilio have no flutter packages for these APIs. Is it possible to use Twilio in my app and what are the alternatives if not.
There is no reason that you cannot use Twilio in your Flutter application to do real time chat and audio/video calls. At Twilio we do not officially support Flutter as a platform, but there are community built plugins that wrap both the Video and Conversations API that might help you out.
