Firebase Setup (Flutter)

Firebase is required for Bubbl push token and delivery flows on both Android and iOS.

Android

1. Add google-services.json to android/app/.
2. Apply Google Services plugin in android/app/build.gradle.kts.
3. Ensure package name in Firebase project matches your Android applicationId.

iOS

1. Add GoogleService-Info.plist to Runner target.
2. Configure Firebase in AppDelegate before Bubbl runtime operations.
3. Set Messaging.messaging().delegate = self.
4. Forward APNs token and FCM token:

BubblPlugin.updateAPNsToken(deviceToken)
BubblPlugin.updateFCMToken(token)

Verification checklist

• boot succeeds without Firebase initialization errors.
• Device receives push token updates.
• Notification payloads reach notificationEvents() stream.
• Notifications work in foreground and background-open flows.
