EventChannel class
A named channel for communicating with platform plugins using event streams.
Stream setup requests are encoded into binary before being sent,
and binary events and errors received are decoded into Dart values.
The MethodCodec used must be compatible with the one used by the platform
plugin. This can be achieved by creating an EventChannel counterpart of
this channel on the platform side. The Dart type of events sent and received
is dynamic, but only values supported by the specified MethodCodec can
be used.
The logical identity of the channel is given by its name. Identically named channels will interfere with each other's communication.
