위와 같은 에러가 떴다 .....

왜일까 ....

 

찾아 보니 api랑 데이터를 주고 받는데 문제라고 한다.

 

try {
  final result =
      await http.post(url, body: encodedBody, headers: apiHeader);
  Map<String, dynamic> response = json.decode(result.body);

  print("Response: $response");

  return response;
} catch (error) {
  Map<String, dynamic> response = Map<String, dynamic>();
  response['success'] = false;
  response['message'] = error;
  return response;
}

 코드는 위와 같았는데 ㅋㅋㅋ

 

한참을 찾아도 api문제는 아니고 잘 오는데 가끔 위와 같은 connection error가 떠서

 

stackoverflow의 도움을 받으려 했지만 실패ㅋㅋㅋㅋ

 

알고 보니 .... android emulator문제.. 이놈의 에뮬...문제가 많다 ..
