11 months ago Thanks for the report. I am able to replicate this running the plugin example on web. Tried the same on mobile wherein, the said error doesn't occur. Also, this isn't specific to Windows, as I am on mac and the error is replicable on it. Upon hot restarting the app, the token is generated successfully.

11 months ago @daniel-jaramillo-expe I have the same issue two days ago. But then I realized that FirebaseMessaging.instance.requestPermission is future method, so I have to make await before get the result.
Future<void> requestPermission() async {
NotificationSettings settings = await FirebaseMessaging.instance.requestPermission(
alert: true,
announcement: false,
badge: true,
carPlay: false,
criticalAlert: false,
provisional: false,
sound: true,
);
debugPrint('User granted permission: ${settings.authorizationStatus}');
if (settings.authorizationStatus == AuthorizationStatus.authorized) {
final fcmToken = await _instance.getToken(vapidKey: kIsWeb ? webPushCertificate : null);
debugPrint('fcmToken => $fcmToken');
}
}
I hope it can solve your problem.

@daniel-jaramillo-expe - does this resolve your issue?

11 months ago @russellwheatley yes, it is in fact a synchrony problem as @tontonanrakyat states. To test it, I just change _TokenMonitor class in permissions.dart repo example file to this
class _TokenMonitor extends State<TokenMonitor> {
String? _token;
late Stream<String> _tokenStream;
void setToken(String? token) {
print('FCM Token: $token');
setState(() {
_token = token;
});
}
@override
void initState() {
super.initState();
getToken();
_tokenStream = FirebaseMessaging.instance.onTokenRefresh;
_tokenStream.listen(setToken);
}
void getToken() { // This a new method
FirebaseMessaging.instance
.getToken(
vapidKey:
'BHPVRHXKku9DXdy1X_WY-Bfdy4gf0WuTctbfqCwktI9kVTAYwos-FGsWInnl96P13sXiOd09JxHNGACpjRhTcZc')
.then(setToken);
}
@override
Widget build(BuildContext context) {
return Column(
children: [
widget._builder(_token),
ElevatedButton(onPressed: getToken, child: const Text('Get token')) // This a new button
],
);
}
}After accepting the required permissions, if I hit the new Get token button, it fetches the token correctly. Thanks! 😊

11 months ago Still, I get this error even with await getToken. It happens only on first time when I request it. Similar issue on firebaseJS https://github.com/firebase/firebase-js-sdk/issues/5797

11 months ago hi. i have the same issue. I get this error: "Error: AbortError: Failed to execute 'subscribe' on 'PushManager': Subscription failed - no active Service Worker " when I run my Flutter app for the first time on Chrome browser, but if I restart the app or refresh the browser page, the error disappears.

11 months ago Hi all... After upgrade to latest flutter and all packages, I have the same problem again. (it happened after "flutter clean") But I can handle this with "deleteToken()" before "requestPermission()".
Future<void> requestPermission() async {
try {
NotificationSettings settings = await _instance.requestPermission();
debugPrint('User granted permission: ${settings.authorizationStatus}');
if (settings.authorizationStatus == AuthorizationStatus.authorized) {
if (kIsWeb) {
await _instance.deleteToken();
}
//! not works on web
_instance.onTokenRefresh.listen(
(fcmToken) => debugPrint('fcmToken [stream] => $fcmToken'),
onError: (err) => debugPrint(err),
);
_instance
.getToken(vapidKey: kIsWeb ? webPushCertificate : null)
.then((value) => debugPrint('fcmToken [future] => $value'));
}
} catch (e) {
debugPrint(e.toString());
}
}And I found that "onTokenRefresh" not works on web, but works properly on android

Thanks, using deleteToken before getToken works, this error does not show up

Deleting the token worked for me too. Thank you.

Deleting a token that doesnt exists causes an error.
Will wait for a real fix for this issue, as of right now the examples and documentations are wrong so how can this be closed?

11 months ago @RomanIvn This seems to be a different issue than the one reported in this issue. You may file a separate issue for better tracking.

This only happens in iOS I believe when the user has not seen notification permission. You can solve it via getNotificationSettings method. If you see that user was shown the permission dialog from ios before and it was granted then you can delete it otherwise don't need to delete token for iOS.
Bug report
Describe the bug When I run the project for the first time, it is unable to get the FCM Token. It is needed that the page to be reloaded.
Steps to reproduce
Steps to reproduce the behavior:
Expected behavior
It would be expected that as soon as the app get permisions to receive notifications, it can get the FCM Token successfully
Sample project
Run the firebase_messaging repo example at: https://pub.dev/packages/firebase_messaging/example
