Flutter - how to get refreshed Firebase's app token

Question

I am new to Firebase Cloud Messaging. While I was developing and using single AVD to test, I noticed that the token changed.

There is a similar question, but it does not help when developing with Flutter.

How can I get the new token? Will the token change while the app is running or in between app stop and start?

In the other question's answer, it says:

As you pointed out the token can change, in which case the onTokenRefresh() method will be called again.

How will it happen in case of Flutter?

it seems more complex with https://stackoverflow.com/questions/39157236/firebase-cloud-messaging-auth-tokens-vs-registration-token — , Mar 30 '20 at 03:27

You can listen to it in Flutter. Use,

firebaseMessaging.onTokenRefresh.listen((token) => saveOrSendToken(token));

both time. Check it with your previous saved token. – Abhay Koradiya Mar 30 '20 at 04:15
because every time when app start then this callback called. see [here](https://github.com/FirebaseExtended/flutterfire/issues/1824) – Abhay Koradiya Mar 30 '20 at 04:16
