How to get the device token in flutter

I'm trying to get the device token, for this i'm using FirebaseMessaging. here is my code to get the token.

@override
  void initState()  {
 FirebaseMessaging? _firebaseMessaging;
 _firebaseMessaging?.getToken().then((token){
      print("token is $token");
});
}

but it print nothing. Please help how to do this.

Solution

  • You have to create the FirebaseMessaging instance. Change to:

    @override
void initState() {
  FirebaseMessaging _firebaseMessaging = FirebaseMessaging.instance; // Change here
  _firebaseMessaging.getToken().then((token){
    print("token is $token");
  });
}
