# IOSink constructor

IOSink(StreamConsumer<List<int>> target, { Encoding encoding: utf8 })

Create an IOSink that outputs to a `target` StreamConsumer of bytes.

Text written to StreamSink methods is encoded to bytes using `encoding` before being output on `target`.

## Implementation

    factory IOSink(StreamConsumer<List<int>> target, {Encoding encoding: utf8}) =>
        new _IOSinkImpl(target, encoding);
