void hideCurrentMaterialBanner({ MaterialBannerClosedReason reason = MaterialBannerClosedReason.hide }) {
  assert(reason != null);
  if (_materialBanners.isEmpty || _materialBannerController!.status == AnimationStatus.dismissed)
    return;
  final Completer<MaterialBannerClosedReason> completer = _materialBanners.first._completer;
  if (_accessibleNavigation!) {
    _materialBannerController!.value = 0.0;
    completer.complete(reason);
  } else {
    _materialBannerController!.reverse().then<void>((void value) {
      assert(mounted);
      if (!completer.isCompleted)
        completer.complete(reason);
    });
  }
