使用 flutter 构建时， flutter 终端/控制台充满 "greyList API"异常

Question

我正在 flutter 中开发，我的 logcat 总是充满了这些日志

它谈论的是一些“灰名单”API，我阅读了它，我从文档中最多可以得出灰名单 API 是安全问题。
话虽如此，我确实希望摆脱这些异常，但我无法更改任何 API。
我怀疑有问题的库是:
flutter_google_maps:^3.8.0
每次运行此特定代码时，logcat 中都充满了垃圾异常。

  class Map extends StatelessWidget {
  final GlobalKey<GoogleMapStateBase> _key;

  Map(this._key);

  @override
  Widget build(BuildContext context) {
    return Consumer<ReceiverDataModel>(
      builder: (context, state, child) => StreamBuilder<QuerySnapshot>(
        stream: Db.getStream(state.code),
        builder: (context, snapshot) {
          print(snapshot.data);
          return GoogleMap(
            key: _key,
            initialPosition: GeoCoord(30.1290, 77.2674),
            initialZoom: 20,
            mapType: MapType.roadmap,
            //markers: markers,
            mobilePreferences: MobileMapPreferences(
                myLocationEnabled: true, myLocationButtonEnabled: true),
          );
        },
      ),
    );
  }
}

logcat 使我很难看到我试图打印的一些重要信息。我只想抑制这些异常。
谢谢你的时间。

如果使用 IntelliJ 控制台，您可以通过右键单击 + 像这样折叠线条来“折叠”这些无用的线条。
如果使用终端，您可以将输出通过管道传递给 grep 命令。
