public static boolean sendBroadcast(Object instance, Intent intent) {
        return ((PluginLocalBroadcastManager) instance).sendBroadcast(intent);
    }
Like {@link #sendBroadcast(Intent)}, but if there are any receivers for
the Intent this function will block and immediately dispatch them before
returning.
