‘无法获取远程配置。缓存或默认值将“使用”flutter

Question

我已经为flutter设置了firebase配置

根据文档https://pub.dev/packages/firebase_remote_config#-readme-tab-

我的钥匙是

Flutter应用程序中的远程配置在获取时引发异常

try {
              remoteConfig.getString('welcome')[![enter image description here][1]][1]
              // Using default duration to force fetching from remote server.
              await remoteConfig.fetch(expiration: const Duration(seconds: 0));
              await remoteConfig.activateFetched();
     } on FetchThrottledException catch (exception) {
              // Fetch throttled.
              print(exception);
    } catch (exception) {
              print(
                  'Unable to fetch remote config. Cached or default values will be '
                  'used');
}

通常当你与这些问题斗争时，最后一切都搞混了。我想在发布后，您已经可以看到配置的值，但在查询另一个参数名时会发生错误。添加以下行以查看得到的实际错误。

打印('exception:$exception')；

try {
      await remoteConfig.fetch(expiration: const Duration(seconds: 0));
      await remoteConfig.activateFetched();
      String forceUpdateCurrentVersion =
          remoteConfig.getString('force_update_current_version');
      double newVersion =
          double.parse(forceUpdateCurrentVersion.trim().replaceAll(".", ""));
      if (newVersion > currentVersion) {
        _showVersionDialog(context);
      }
    } on FetchThrottledException catch (exception) {
      // Fetch throttled.
      print(exception);
    } catch (exception) {
      print('EXCEPTION: $exception');
      print('Unable to fetch remote config. Cached or default values will be '
          'used');
    }
