MissingPluginException(No implementation found for method checkUpgrade on channel crazecoder/flutter_bugly)

实现一个检查更新的功能，使用checkUpgrade 写了一个demo跑了下，报下面的错，看起来是插件内部报错了

demo代码片段：

` onTap: () {

          /// 手动检查更新
          ///参考文档：
          ///   https://github.com/crazecoder/flutter_bugly/blob/7b71c8644085ed843db61b75aa868fbfd4d85af3/example/lib/main.dart

          FlutterBugly.checkUpgrade(isManual: true, isSilence: false, useCache: false).then((UpgradeInfo info) {

            if (info != null && info.id != null) {
              //upgradeType = 1;//2为强制更新
              String message = sprintf('title: %s newFeature: %s apkUrl: %s upgradeType: %s versionCode: %s versionName : %s publishTime: %s', [
                info.title, 
                info.newFeature,
                info.apkUrl,
                info.upgradeType,
                info.versionCode,
                info.versionName,
                info.publishTime,
              ]);
              print("检查更新信息： " + message);
              Fluttertoast.showToast(msg: message,);
            }
          });
        },
