# 🔔 smart_firebase_fcm

A plug-and-play Firebase FCM (Push Notification) package for Flutter — with full support for foreground/background notifications, deep link redirection, local notifications, and manual toggles for Firebase Analytics and Crashlytics.

---

## ✨ Features

- ✅ One-line Firebase + FCM initialization
- ✅ Foreground + background + terminated notification redirection
- ✅ Foreground local notifications via `flutter_local_notifications`
- ✅ Android notification channel configuration
- ✅ Optional: Firebase Analytics and Crashlytics (enabled/disabled via flags)
- ✅ Clean, modular code — easy to extend

---

## 🚀 Quick Start

### 1. Enable or disable Firebase features

```dart
import 'package:smart_firebase_fcm/smart_firebase_fcm.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  FirebaseFeatureFlags.enableAnalytics = false;
  FirebaseFeatureFlags.enableCrashlytics = true;
  FirebaseFeatureFlags.enableFCM = true;

  await FCMInitializer.initialize(
    onTap: FCMHandler.handleMessage,
  );

  runApp(const MyApp());
}

2. Handle redirection from notification tap #

void handleMessage(RemoteMessage message) {
  final type = message.data['type'];

  switch (type) {
    case 'order':
      // Navigate to order screen
      break;
    case 'chat':
      // Navigate to chat screen
      break;
    default:
      // Fallback or log unknown type
      break;
  }
}

3. Get the FCM device token #

final token = await FCMInitializer.getDeviceToken();
print("FCM Token: $token");

📦 Installation #

Add to your pubspec.yaml:

dependencies:
  smart_firebase_fcm: ^1.0.0

🔧 Notification Payload Structure (Recommended) #

Make sure your backend sends data payload for redirection:

{
  "notification": {
    "title": "New Order!",
    "body": "You have a new order."
  },
  "data": {
    "type": "order",
    "order_id": "12345"
  }
}

🧱 Under the Hood #

• ✅ Firebase.initializeApp() + permission handling

• ✅ FCM listeners for:

  • onMessage (foreground)
  • onMessageOpenedApp (background)
  • getInitialMessage() (terminated)

• ✅ Local notifications via flutter_local_notifications

• ✅ Android notification channel setup

• ✅ Feature flags to disable/enable:

  • Firebase Analytics
  • Firebase Crashlytics
  • Firebase Messaging

🧪 Example App #

❓ FAQ #

Q: Will it work without Firebase Analytics or Crashlytics? A: Yes! You can disable them individually using FirebaseFeatureFlags.

Q: Can I customize redirection behavior? A: Absolutely. Modify the FCMHandler.handleMessage() function with your own navigation logic.

Q: Does this support iOS and Android? A: Yes, both are supported. Make sure you configure notification permissions on iOS correctly.
