# Firebase In-App Messaging Skill

This skill defines how to correctly implement Firebase In-App Messaging in Flutter applications, covering setup, programmatic triggers, privacy controls, testing workflows, and campaign management.

## When to Use

Use this skill when:

* Setting up Firebase In-App Messaging in a Flutter project.
* Triggering or suppressing in-app messages programmatically.
* Implementing opt-in data collection for GDPR or user privacy compliance.
* Testing campaigns with specific devices before rollout.
* Configuring message types, targeting rules, and A/B tests.

## 1. Setup and Configuration

```
flutter pub add firebase_in_app_messaging
```

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

- Initialize Firebase before using any In-App Messaging features.
- In-App Messaging **retrieves messages from the server once per day** by default to conserve power.

### Setup Checklist

1. Confirm `Firebase.initializeApp()` completes before accessing In-App Messaging.
2. Create a test campaign in the Firebase console to verify the integration.
3. Locate the Installation ID for device-specific testing (see Testing section).

---

## 2. Message Triggering and Display

Use Google Analytics events to trigger in-app messages without additional code. For programmatic triggering:

```dart
// Trigger a message tied to a custom event
await FirebaseInAppMessaging.instance.triggerEvent("purchase_complete");
```

### Suppress Messages During Critical Flows

```dart
class PaymentScreen extends StatefulWidget {
  @override
  State<PaymentScreen> createState() => _PaymentScreenState();
}

class _PaymentScreenState extends State<PaymentScreen> {
  @override
  void initState() {
    super.initState();
    // Suppress messages during payment
    FirebaseInAppMessaging.instance.setMessagesSuppressed(true);
  }
