# IOSink constructor Null safety

IOSink(

1. StreamConsumer<List<int>> target,
2. {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);
