ChannelBuffers class
Storage of channel messages until the channels are completely routed, i.e. when a message handler is attached to the channel on the framework side.
Each channel has a finite buffer capacity and in a FIFO manner messages will be deleted if the capacity is exceeded. The intention is that these buffers will be drained once a callback is setup on the BinaryMessenger in the Flutter framework.
Clients of Flutter shouldn't need to allocate their own ChannelBuffers
and should only access this package's channelBuffers if they are writing
their own custom BinaryMessenger.

with any size. The correct size should be chosen for the semantics of your
channel. [...]
