StreamReader<T> class

Use for get stream element by read StreamReader can get one element from stream by read method

Design

StreamReader has only one constructor and one parameter, call "RawDataStream". While StreamReader creating, subscribe RawDataStream and control it.

read :

RawDataStream -> Completer -> Read

When read method call, _subscription will call resume, recv new data to Completer as result read return, and then _subscription call pause again.

releaseStream:

If you need data stream instead of read again and again, call releaseStream. Subscription will always resume and never pause again until it done. At this time, read return null forever.
