startChunkedConversion method Null safety

ChunkedConversionSink<Object?> startChunkedConversion (
  1. 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);
}
