# startChunkedConversion method

ChunkedConversionSink<Object> startChunkedConversion (Sink<String> sink)
override

Starts a chunked conversion.

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

Returns a chunked-conversion sink that accepts at most one object. It is an error to invoke `add` more than once on the returned sink.

## Implementation

    ChunkedConversionSink<Object> startChunkedConversion(Sink<String> sink) {
      if (sink is _Utf8EncoderSink) {
        return _JsonUtf8EncoderSink(
            sink._sink,
            _toEncodable,
            JsonUtf8Encoder._utf8Encode(indent),
            JsonUtf8Encoder._defaultBufferSize);
      }
      return _JsonEncoderSink(
          sink is StringConversionSink ? sink : StringConversionSink.from(sink),
          _toEncodable,
          indent);
    }
