Builds Dart protocol buffers.

Example: #

Make a protobuf file:

syntax = "proto2";

package address_book;

message Person {
    required string name = 1;
    required int32 id = 2;
    optional string email = 3;

    enum PhoneType {
        MOBILE = 0;
        HOME = 1;
        WORK = 2;
    }

    message PhoneNumber {
        required string number = 1;
        optional PhoneType type = 2 [default = HOME];
    }

    repeated PhoneNumber phones = 4;
}

message AddressBook {
    repeated Person people = 1;
}

Run the command:

pbuf address_book.proto

Enjoy your new Protocol Buffer!

import 'package:dart_protobuf_example/address_book.pb.dart';

main() {
  var people = [
    new Person()..name = "Jack Ryan"..email = "jack.ryan@gmail.com",
    new Person()..name = "Brad Ryan"..email = "brad.ryan@gmail.com"
  ];
  var x = new AddressBook();
  x.people.addAll(people);
