Implementation

Future<Map<String, dynamic>> post(Uri url, dynamic data) async {
  try {
    final HttpClientRequest req = await HttpClient().postUrl(url);
    req.headers.contentType = ContentType.json;
    req.write(jsonEncode(data));
    final HttpClientResponse res = await req.close();
    final responseBody = await res.transform(utf8.decoder).join();
    final responseJson = jsonDecode(responseBody) as Map<String, dynamic>;
    return {'error': false, ...responseJson};
  } catch (e) {
    return {'error': true, 'errorData': e};
  }
}
