getToken: null token. (android)

[Tolfx]

When I call the method window.cordova.plugins.firebase.messaging.getToken() I get null.

And not entirely sure what I'm doing wrong, what I've read I should just call it and get a token. And when I looked at the Java file and compare it with the older versions I can't really understand what went wrong.

I fixed it by doing like this:

    @CordovaMethod
    private void getToken(String type, final CallbackContext callbackContext) {
        // type can still be null, so if we call type.isEmpty() and is null it will crash.
        if (type != null && type.isEmpty()) {
            callbackContext.sendPluginResult(
                    new PluginResult(PluginResult.Status.OK, (String)null));
        } else {
            firebaseMessaging.getToken().addOnCompleteListener(cordova.getActivity(), task -> {
                if (task.isSuccessful()) {
                    callbackContext.success(task.getResult());
                } else {
                    callbackContext.error(task.getException().getMessage());
                }
            });
        }
    }

But if there is another solution I wouldn't mind getting a answer. Since I rather just not mess with the source unless I really need to.
