@domesticmouse, could you take a look?

I ran the following code in a new Dart project under Dart 2.9.1. This code is a lightly edited version of the complete example in the linked page:

import 'dart:async';
import 'dart:convert';
import 'dart:io';

import 'package:http/http.dart' as http;

Future<Album> fetchAlbum() async {
  final response = await http.get(
    'https://jsonplaceholder.typicode.com/albums/1',
    headers: {HttpHeaders.authorizationHeader: 'Basic your_api_token_here'},
  );
  final responseJson = json.decode(response.body);

  return Album.fromJson(responseJson);
}

class Album {
  final int userId;
  final int id;
  final String title;

  Album({this.userId, this.id, this.title});

  factory Album.fromJson(Map<String, dynamic> json) {
    return Album(
      userId: json['userId'],
      id: json['id'],
      title: json['title'],
    );
  }

  @override
  String toString() {
    return 'Album(userId: $userId, id: $id, title: $title)';
  }
}

void main(List<String> arguments) async {
  var album = await fetchAlbum();
  print(album);
}

It worked as expected:

$ pub run bin/main.dart 
Album(userId: 1, id: 1, title: quidem molestiae enim)

The code looks fine to me. What do you think @domesticmouse ?

As far as I can tell, the cookbook code is working as intended.
