Getting the result of a method Future<T> flutter

I have a method 

Future<FirebaseUser> getCurrentUser() async {
    FirebaseUser user = await _firebaseAuth.currentUser();
    return user;
}

I want to be able to call it in some other module by doing :

if (class.getCurrentUser() != null) {
    // Do something
}

I cannot seem to figure out how to get the actual value, and not the Future object storing the value. In C++ for instance, I can just do future.get(), which will block and return the value to me. Is there an equivalent in flutter? I am new to the language and have searched for hours and cannot seem to find a solution to this exact problem.

From your code, it seems you actually need 1 await only:

Future<FirebaseUser> getCurrentUser() async {
    return _firebaseAuth.currentUser();
}

if (await class.getCurrentUser() != null) {
    // Do something
}

You have to await for the result in your method call as well like this:

FirebaseUser currentUser = await class.getCurrentUser();
if (currentUser != null) {
    // Do something
}
