FlutterBugly.postCatchedException((){false;runZonedGuarded(() { runApp(MyApp()); }, reportError);
});???????void reportError(Object, StackTrace) async {// print('收集到错误: $Object, $StackTrace');var path = await getFilePath('error');var name = utils.CustomStampToTime_str(Date: '${userInfo.userid}@YY.MM.DD');var _has = await checkCache('$name', file: 'error');File _errFile = File('${path}/${name}');String errMsg = await readCache(name, type: 'error');errMsg += '\n==================';errMsg += '\n';errMsg += '时间：${utils.CustomStampToTime_str(Date: 'YY-MM-DD hh:mm:ss')}';errMsg += '\n';errMsg += '$Object';errMsg += '\n';errMsg += '$StackTrace';errMsg += '\n';await _errFile.writeAsString(errMsg);// print('完成');
