How to prevent flutter app from crashing after Dio error?

I am using the flutter-dio package to make HTTP requests and have made a wrapper on it from my convenience like so

  Future<dynamic> post(String uri, dynamic body, {String authKeyCust}) async {
    authKey = await SecureStorage.getAuthKey();
    try {
      Response response = await dio.post(
        uri,
        data: body,
        options: Options(headers: {"authkey": authKeyCust ?? "$authKey"}),
      );
      return response.data;
    } on DioError catch (error) {
      print('error: $error');
    } on SocketException catch(error) {
      print('No net');
    }
  }

All I want is the app to not crash/pause on exception when any error occurs.
