To initialize Amplify Push Notifications, you will need to configure Amplify add the Auth and Push Notifications plugins. To complete initialization, call `Amplify.configure`

Your resulting code should look something like the following:

```dart
// Example main.dart

import 'package:amplify_auth_cognito/amplify_auth_cognito.dart';
import 'package:amplify_flutter/amplify_flutter.dart';
import 'package:amplify_push_notifications_pinpoint/amplify_push_notifications_pinpoint.dart';

import 'amplifyconfiguration.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

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

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();
    _configureAmplify();
  }

  Future<void> _configureAmplify() async {
    try {
      final authPlugin = AmplifyAuthCognito();
      final pushPlugin = AmplifyPushNotificationsPinpoint();
      await Amplify.addPlugins([authPlugin, pushPlugin]);
      await Amplify.configure(amplifyconfig);
    } on Exception catch (e) {
      safePrint('An error occurred configuring Amplify: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    // Your application UI
  }
}
```
