How to get the ID token from FirebaseAuth

Question

I am reading some Json files from my firebase database and I am trying to obtain an ID token for the current user to be used in the header as follows:

 var respo         


        

Answer 1

I think that there is a bug in Flutter.

Now to call the method getIdToken() you need to do this:

FirebaseUser user = await FirebaseAuth.instance.currentUser();

String token;

user.getIdToken().then((result) {

    token = result.token;
});

You can't call FirebaseAuth.instance.currentUser().getIdToken()
