[firebase_admob] "load() return" CURRENT NOT listener load event, can it update?

[peterweb2005]

ie: load return

    // load
    final bool load = await ad.load();
    log.finest('load: ', load);

ie: listener load event

    BannerAd(
      listener: (MobileAdEvent event) {
        switch (event) {
          case MobileAdEvent.loaded:

load return, return almost immediately, ad NOT finished load
listener load event, really ad load finished
