IOSink abstract class A combined byte and text output. An IOSink combines a StreamSink of bytes with a StringSink, and allows easy output of both bytes and text. Writing text (write) and adding bytes (add) may be interleaved freely. While a stream is being added using addStream, any further attempts to add or write to the IOSink will fail until the addStream completes. It is an error to add data to the IOSink after the sink is closed.  Implements   
StreamSink<List<int>> StringSink   Implemented by  HttpClientRequest HttpResponse Socket Stdout   Constructors   IOSink(StreamConsumer<List<int>> target, { Encoding encoding: UTF8 }) factory
  Create an IOSink that outputs to a target StreamConsumer of bytes.   Properties   done → Future read-only
  Get a future that will complete when the consumer closes, or when an error occurs. This future is identical to the future returned by close.   encoding → Encoding read / write
  The Encoding used when writing strings. Depending on the underlying consumer this property might be mutable.   hashCode → int read-only, inherited
  The hash code for this object.   runtimeType → Type read-only, inherited
  A representation of the runtime type of the object.   Operators   operator ==(other) → bool inherited
  The equality operator.   Methods   add(List<int> data) → void    Adds byte data to the target consumer, ignoring encoding.   addError(error, [ StackTrace stackTrace ]) → void    Passes the error to the target consumer as an error event.   addStream(Stream<List<int>> stream) → Future   Adds all elements of the given stream to this.   close() → Future   Close the target consumer.   flush() → Future   Returns a Future that completes once all buffered data is accepted by the underlying StreamConsumer.   write(Object obj) → void    Converts obj to a String by invoking Object.toString and adds the encoding of the result to the target consumer.   writeAll(Iterable objects, [ String separator = "" ]) → void    Iterates over the given objects and writes them in sequence.   writeCharCode(int charCode) → void    Writes the character of charCode.   writeln([Object obj = "" ]) → void    Converts obj to a String by invoking Object.toString and writes the result to this, followed by a newline.   noSuchMethod(Invocation invocation) → dynamic  inherited
  Invoked when a non-existent method or property is accessed.   toString() → String inherited
  Returns a string representation of this object.
