Flutter – Widget builded with null value from api call in initState

I’m having trouble displaying the result of api call in widget.
I’m getting "Unexpected null value" error.
From some reasons I don’t want to use FutureBuilder in this case. With FutureBuilder everything is ok.

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

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

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

void main() => runApp(const MyApp());

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  Album ? myAlbum;
  Future<void>  fetchAlbum() async {
    final response = await http
        .get(Uri.parse('https://jsonplaceholder.typicode.com/albums/1'));

    if (response.statusCode == 200) {
      // If the server did return a 200 OK response,
      // then parse the JSON.
      myAlbum= Album.fromJson(jsonDecode(response.body));
    } else {
      // If the server did not return a 200 OK response,
      // then throw an exception.
      throw Exception('Failed to load album');
    }
  }
  @override
  void initState() {
    fetchAlbum();
    super.initState();
  }
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Fetch Data Example',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Fetch Data Example'),
        ),
        body: Center(
          child: Text(myAlbum!.title)
        ),
      ),
    );
  }
}

I assume that problem is because widget is builded before initState call.
