edit: it is supposed to look like it does on the device log, according to Firebase support
I am adding push notifications via FCM to my Flutter app, but the message format is very different on the iOS Simulator vs. my iPhone 5s.
When receiving a push notification from the Firebase console to an active/opened app.
Problem: What do I need to do to make sure the real device receives the message in the correct format?
Log from Simulator (iPhone XR, 12.2) (looks like in the official code examples):
onMessage: {
from: 123000000000,
collapse_key: com.mydomainnamehere,
notification: {
body: Lorem ipsum,
title: Title,
e: 1,
tag: campaign_collapse_key_9876543210011223344
}
}
Log from real device (iPhone 5s, 12.2) (can't find any references online to this):
onMessage: {
google.c.a.c_l: notif_name,
google.c.a.e: 1,
aps: {
alert: {
title: Title,
body: Lorem ipsum
}
},
gcm.n.e: 1,
google.c.a.c_id: 9876543210011223344,
google.c.a.udt: 0,
gcm.message_id: 1234567800998877,
google.c.a.ts: 1234567800
}
The notification is sent from the Firebase console to all devices, the logs are taken from the same notification (but I anonymized the id's).
The Device and Simulator is running the same Flutter code from Android Studio, at the same time.
Parts of my pubspec.yaml that refers to FCM
firebase_core: ^0.4.0+1
firebase_auth: 0.11.1
cloud_firestore: ^0.11.0+2
firestore_ui: ^1.4.0
firebase_messaging: ^5.0.2
Software and SDK Versions
Flutter Channel dev, v1.8.4,
Mac OS X 10.14.5,
Android SDK version 28.0.3,
Xcode 10.2.1,
Android Studio version 3.4
Flutter message-handling code
void initState() {
super.initState();
if (Platform.isIOS) {
iosSubscription = _fcm.onIosSettingsRegistered.listen((IosNotificationSettings settings) {
print("FCM settings received: $settings");
});
_fcm.requestNotificationPermissions(IosNotificationSettings());
}
_fcm.configure(
onMessage: (Map message) async {
print("onMessage: $message");
},
);
getFcmToken();
}
void getFcmToken() async {
var token = await FirebaseMessaging().getToken();
print("Token $token");
}
I was expecting that the JSON format would be the same on both the simulator and a real device. But the real device isn't even receiving all of the notification.
