flutterjanus

Flutter plugin for Janus Gateway. flutterjanus is port of janus.js. All the functions and calls are mapped in flutter to make things easy for porting an existing javascript app for flutter. The calls are modified only to suit the static typing of the flutter.

Organisation

The code is organised in four files

  • janus.dart - This file contains the static calls and basic transport mechanism with the backend janus server
  • session.dart - This file is the heart of the whole plugin. All the janus.js calls are mapped in this file with same nomenclature. Some of the code inside the files are commented with // FIX ME to take care of the flutter requirements. A lot of code inside this file is not required as those are browser specific which will be cleaned at later date when all the tests are working properly.
  • plugin.dart - This file defines the template plugin which is initialised when a webrtc session is set. In janus.js this is defined a dictionary one time for websocet and one time for the http. This has been moved to seperate file to provide a template strucutre and also to enable static type checking in flutter.
  • callbacks.dart - This file defines the template callbacks which are used in janus.js. A single point definition of the callback structure enables better code checking in flutter.
