    [tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"event"
                                                          action:@"action"
                                                           label:@"label"
                                                           value:@(1)] build]];

    [[GAI sharedInstance] dispatch];
    [[GAI sharedInstance] dispatchWithCompletionHandler:^(GAIDispatchResult result) {
