How to get the ID token from FirebaseAuth?

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

getIdTokenResult() returns a Future – you have to await it to actually get the token string:

IdTokenResult tokenResult = await FirebaseAuth.instance.currentUser.getIdTokenResult(); 
var response = await httpClient.get(url,headers: {'Authorization':"Bearer ${tokenResult.token}"});

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

FirebaseUser user = await FirebaseAuth.instance.currentUser;

String token;

user.getIdTokenResult().then((result) {

    token = result.token;

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

then you can access the token with

var tokenResult = await response.user.getIdTokenResult();
log('TokenID ${tokenResult.token}');

and after that, you can use it into

var response = await httpClient.get(url,headers: {'Authorization':"Bearer $token"});
