# startChunkedConversion method Null safety

ByteConversionSink startChunkedConversion (

1. Sink<String> sink

)

Starts a chunked conversion.

The converter works more efficiently if the given `sink` is a StringConversionSink.

## Implementation

    ByteConversionSink startChunkedConversion(Sink<String> sink) {
      StringConversionSink stringSink;
      if (sink is StringConversionSink) {
        stringSink = sink;
      } else {
        stringSink = StringConversionSink.from(sink);
      }
      // TODO(lrn): Use stringSink.asUtf16Sink() if it becomes available.
      if (!_allowInvalid) return _Latin1DecoderSink(stringSink);
      return _Latin1AllowInvalidDecoderSink(stringSink);
    }
