Usage #
The usage is pretty straightforward:
import 'package:ndjson/ndjson.dart';

// Your ndjson stream.
final Stream<String|List<int>> ndjsonStream = ...

// A new stream that will parse all chunks and emit events
// for each new json object (not ndjson chunks).
final Stream<NdjsonLine> parsedNdjson = ndjsonStream.parseNdjson();

// Using converter functions:
final Stream<Dummy> ndjson = ndjsonSource.parseNdjsonWithConverter<Dummy>(
whenMap: Dummy.fromJson,
);

Supported ndjson types are:

Stream<List<int>>.
Stream<Uint8List>.
Stream<String>.


Any list-like ndjson source can be converted to Stream using:
Stream.fromIterable(ndjsonList);

You must be aware that using ndjson as list is the same as a regular json (you lose all ndjson performance benefits).
