msgpack2 2.0.0

MsgPack for Dart

MsgPack for Dart

A full-featured MsgPack library for Dart 1.x and 2.x.

Attribution

This package was originally forked from msgpack. Due to the number of incompatible refactorings and loss of backwards compatibility, the decision was made to spin it off as a new package. This package contains numerous enhancements over the original MsgPack implementation which should help with performance in many places (see benchmarks), as well as a more complete testing suite.

Usage

Because this project relies on Dart Libraries which contain inconsistencies between Dart 1.x and Dart 2.x, there are two versions of the this package maintained.

If you want to use this package for Dart projects with Dart 2.x, please ensure your version dependencies are set to:

  dependencies:
    msgpack2: ^2.0.0

If you want to use this package for Dart projects with Dart 1.x, please ensure your version dependencies are set to:

  dependencies:
    msgpack2: ^1.0.0

Simple Example

import "dart:typed_data";

import "package:msgpack/msgpack.dart";

main() {
  var binary = new Uint8List.fromList(
    new List<int>.generate(40, (int i) => i)
  ).buffer.asByteData();

  var data = {
    "String": "Hello World",
    "Integer": 42,
    "Double": 45.29,
    "Integer List": [1, 2, 3],
    "Binary": binary,
    "Map": {
      1: 2,
      3: 4
    }
  };

  List<int> packed = pack(data);
  Map unpacked = unpack(packed);

  print(unpacked);
}
