A simple usage example:

import 'package:firebase_cloud_messaging_flutter/firebase_cloud_messaging_flutter.dart';

void main() async {
  /// My Service Account Json File Content
  final serviceAccountFileContent = <String, String>{
    'type': '',
    'project_id': '',
    'private_key_id': '',
    'private_key': '',
    'client_email': '',
    'client_id': '',
    'auth_uri': '',
    'token_uri': '',
    'auth_provider_x509_cert_url': '',
    'client_x509_cert_url': ''

  /// Add Your Service Account File Content as Map
  var server = FirebaseCloudMessagingServer(

  /// Get Firebase  Messagin Token [Optional, If you want to send message to specific user]
  /// Don't pass token if you want to send message to all registered users
  // String? token = await FirebaseMessaging.instance.getToken();

  /// Send a Message
  var result = await server.send(
      validateOnly: false,
      message: FirebaseMessage(
        notification: FirebaseNotification(
          title: 'Package by Ottoman',
          body: 'Ottoman added something new! 🔥',
        android: FirebaseAndroidConfig(
          ttl: '3s',

          notification: FirebaseAndroidNotification(
            icon: 'ic_notification',
            color: '#009999',
