# startChunkedConversion method Null safety

ByteConversionSink startChunkedConversion (

1. Sink<String> sink

)
override

Starts a chunked conversion.

The returned sink serves as input for the long-running conversion. The given `sink` serves as output.

## Implementation

    ByteConversionSink startChunkedConversion(Sink<String> sink) {
      if (sink is StringConversionSink) {
        return _Utf8Base64EncoderSink(sink.asUtf8Sink(false), _urlSafe);
      }
      return _AsciiBase64EncoderSink(sink, _urlSafe);
    }
