      refreshToken = decodedData['refreshToken'];
    }
    return response.body;
  }

You are running your 2nd call with refreshed token after a delay; and you would print out response.body from the original call that failed. Did you try to remove Future.delayed? — Andrija, Jun 14 '22 at 12:13

Remove last return response; and unnecessary Future.delayed. Something like this could work:

  Future<http.Response> _getAPIById(String pathURL) async {
    try {
      http.Response response = await _ioClient.get(
        Uri.http(ApiConstants.baseUrl, pathURL),
        headers: {
          'Content-Type': 'application/json',
          'Authorization': 'Bearer ' + accessToken!
        },
      );
      if (response.statusCode == 401) {
        await  refreshAccessToken();
        return await _ioClient.get(
          uri,
          headers: {
            HttpHeaders.contentTypeHeader: 'application/json',
            'x-access-token': 'Bearer ' + accessToken!
          },
        );
      } else {
        return response;
      }
    } catch (e) {
      throw Exception('Error occurred');
    }
  }
