/**************************************************************************************************
 This demo application implements real-time messaging, calls, and conferencing capabilities in a 
 Flutter application. It can serve as a guide for integrating these features into your own Flutter 
 projects. Please refer to the tutorial link below for details on getting started, obtaining 
 authentication tokens and other implementation specifics.

 https://docs.mesibo.com/tutorials/get-started/

 You MUST create tokens and initialize them for user1 and user2 in the code below.

 **************************************************************************************************/

/* ============= IMPORTANT NOTE ============
   
   Although the mesibo Flutter SDK includes all essential messaging, call, and conferencing features, 
   it is a limited version compared to the complete native Android and iOS mesibo APIs. 
   The Flutter SDK is actively expanding and will soon have all native mesibo API features. 
   However, if you need any specific native mesibo API not yet in the Flutter SDK, 
   please write to us, and we will prioritize adding that feature.
