Getting Started

Packer and Unpacker classes provide Streaming API for serializing and deserializing data.

Example

Packer

    final p = Packer();
    p.packInt(1);
    p.packInt(2);
    final bytes = p.takeBytes(); //Uint8List
    send(bytes) //send to server

Unpacker

    final List<int> rawBytes = receive() // receive List<int> bytes from server
    final u = Unpacker.fromList(rawBytes);
    final n1 = u.unpackInt();
    final n2 = u.unpackInt();
    expect(n1, equals(1));
    expect(n2, equals(2));

NOTES

Packing Maps and Iterables

• pack Map or Iterable header length
• manually pack all items

Only need put length header before packing items

After packing all items no need to stop or finish or end this map / iterable

    final list = ['i1','i2'];
    final map = {'k1': 11, 'k2': 22};
    final p = Packer();
    p.packIterableLength(list.length);
    list.forEach(p.packString);
    p.packMapLength(map.length);
    map.forEach((key, v) {
      p.packString(key);
      p.packInt(v);
    });
    final bytes = p.takeBytes();

Roadmap

• Sooner will be added convenient functions for automatically packing and unpacking from dart list / map
