startChunkedConversion method
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
@override
ChunkedConversionSink<Object?> startChunkedConversion(Sink<String> sink) => jsonEncoder.startChunkedConversion(sink);
