안드로이드쪽에서 발생하는 문제입니다.

final KakaoLoginResult result = await _kakaoSignIn.logIn();
카카오톡이 설치되어있고 로그인되어 있으면 이 코드가 제대로 실행되지만
아니라면
AUTHORIZATION_FAILED: Failed to get Authorization Code.
이 에러가 발생합니다.

Android studio의 Logcat에서는 아래의 오류가 발생합니다.

이리 저리 많이 찾아 보고 있는데.. 도와주세요.

https://devtalk.kakao.com/t/ios-14-5-2/115366

카카오톡을 설치하지 않은 기기에서 종료가 되고 있습니다.
위의 링크에서는 sdk 버전을 업데이트 하면 된다고 하네요.
혹시 업데이트 가능할까요?

Error when used with Firebase
Errors only occur on Android.

It's okay to use it alone, but when using it with the Firebase, an error such as a picture occurs.

flutter_kakao_login 버전 2.0.0 사용중이고 kakao 로그인 요청시 crash 발생하며 아래는 로그입니다.

첨부 로그 파일도 확인 부탁드립니다.

await 를 걸고 login을 할경우 ios 에서 응답이 오지 않습니다.

카카오 톡으로 넘어가지고 인증버튼을 누를뒤 앱으로 돌아오고 나서도 응답이 오지 않습니다.

해당 코드의 48번 줄이 실행 안되는 것을 보아 ios 네이티브에서 반환을 못하는거 같습니다.

Steps to reproduce:

1. After pressing login button Kakao auth screen shows up, pressing back or disagree button returns user to initial screen
2. After pressing login again and proceeding to Kakao screen again, when pressing back or disagree button for the second time, app crashes.

Started having this issue after updating to flutter_kakao_login: ^1.0.0

iOS works as expected.

Seems like key here is

FirebaseAuth로 사용하려고 하는데 구글로그인과 같이 하는 방법은 없을까요?
AuthCredential을 알아야 하는데 특별한 방법이 있나요?

혹시 userme 에서 gender 정보를 받아오는 부분에 대한 업데이트 계획은 없으실까요?

소스를 받아서 kakaosdk 업데이트 후 수정하려했는데 정보를 받아오는데 어려움이 있네요 ㅠ

iOS에서는 정상적으로 동작하는데 안드로이드에서
flutter_kakao_login: ^0.0.4
를 추가하면, 앱 설치되는 과정에서 죽습니다.

ios13에서 앱설치되어있는 경우 오류가 발생합니다

카카오 로그인화면 띄우고, 로그인 누르면 그상태로 멈춰있습니다.
해당코드는 작성한 개발자쪽에서는 실행되는 상황입니다.

Thank you for making this plugin
i'm using flutter_kakao_login 0.5.0
in android everything is ok
but iphone x and any ios device(installed kakao app) dont get any response after call kakaoSignIn.login() even i dont get any error
//my code

Future<List> kakaoAuth() async {
result = await kakaoSignIn.logIn();
print("login") . <--------------------- ---------------- this print never call;
switch (result.status) {
case KakaoLoginStatus.loggedIn:
try {
KakaoAccessToken accessToken = await (kakaoSignIn.currentAccessToken);

      if (accessToken != null) {
        return [result.account.userID, accessToken.token];
      }
    } catch (err) {
      FlutterCrashlytics().log(err.toString(), tag: "currentAccessToken");
      throw err.toString();
    }

    break;
  case KakaoLoginStatus.loggedOut:
    logger.e("loggedOut");
    break;
  case KakaoLoginStatus.error:
    logger.e("error : ${result.errorMessage}");
    FlutterCrashlytics().log(result.errorMessage, tag: "kakaoAuth");
    throw result.errorMessage;
    break;
}

}

샘플 pubspec.yaml에 google_sign_in: ^3.2.4 를 추가하면 앱이 죽습니다.

카카오로그인과 구글 버전 충돌이 나 빌드가 안되서, project level의 build.gradle에 아래와 같이 추가하니,
빌드 오류는 나지 않습니다.
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "27.0.1"
}
}
}
}

아래와 같은 노트가 나타나기는 하지만, 샘플만 돌렸을때 잘 동작합니다.
Note: /.../flutter/.pub-cache/hosted/pub.dartlang.org/flutter_kakao_login-0.0.5/android/src/main/java/com/josephnk/flutterkakaologin/FlutterKakaoLoginPlugin.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

왜 앱이 죽는지 원인을 모르겠네요?

안녕하세요. 유용한 패키지 만들어주셔서 잘 쓰고 있습니다. 카카오 로그인을 시도하는데, ios, android dev, android profile 모드에서는 로그인이 되지만 android release 로 apk 파일을 빌드해서 설치한 뒤 adb log를 찍어보면, 카카오 로그인 시도 후에 카카오 웹 페이지 열린 뒤에 다음과 같은 에러가 나옵니다.

flutter : LOGIN_ERR 로그인 실패

빌드를 하기 위해 사용하는 명령어는 다음과 같습니다.

flutter build apk --release --flavor production --dart-define=ENV=prd

flutter doctor 결과는 다음과 같습니다.

해결책이 있을지 문의드립니다. 감사합니다.

in English: My flutter app with your package works well in iOS, Android debug and Android profile environment but not working in Android release mode and got one a line of error message.

In debug mode, it works but when i login with release mode and it crashes. This is log:

@JosephNK

이메일 사용 설정을 안했을때 다음과 같이 에러가 여전히 발생 합니다.

java final String userEmail = (resultKakao.getKakaoAccount().getEmail() == null) ? "" : resultKakao.getKakaoAccount().getEmail();

getKakaoAccount() 가 null 이라 에러가 발생합니다.

이해를 돕기 위해 로그켓 내용도 같이 첨부합니다.

예제 올라온데로 돌렸는데 로그인 및 다른 기능은 문제가 없는데 unlink만 에러가 뜨네요.

java.lang.IllegalStateException: Reply already submitted 이렇게 나오는데 무슨 문제일까요?

실행하면 아래와 같이 플러그인을 로드하지 못하는 것 처럼 보이는 오류를 내고 앱이 죽습니다.

flutter clean, flutter pub get, 재부팅, flutter 재설치 등 시도해 보았습니다. ㅠㅠ

안드로이드에서 카카오톡 앱이 열리지 않습니다.

ios 에서 로그인 창에서 키보드가 올라올 때 에러가 발생합니다.
iphone 8 에서는 에러가 발생해도 로그인 버튼을 클릭하면 정상 작동하는데,
iPhone 11 pro max 에서는 같은 에러가 발생하고 로그인 버튼을 눌렀을 떄 먹통이 되버리네요.
왜그럴까요?

	Probably at least one of the constraints in the following list is one you don't want. 
	Try this: 
		(1) look at each constraint and try to figure out which you don't expect; 
		(2) find the code that added the unwanted constraint or constraints and fix it.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
	Probably at least one of the constraints in the following list is one you don't want. 
	Try this: 
		(1) look at each constraint and try to figure out which you don't expect; 
		(2) find the code that added the unwanted constraint or constraints and fix it.

다른 플러그인이 PluginRegistry.ActivityResultListener 를 사용할때 Exception 발생합니다.

@Override
public boolean onActivityResult(int requestCode, int resultCode, Intent data) {
  Log.v(LOG_TAG, "onActivityResult requestCode: " + requestCode + " resultCode: " + resultCode + " data: " + data);
  if (Session.getCurrentSession().handleActivityResult(requestCode, resultCode, data)){
    return false;
  }
  return false;
}

이렇게 작성해 놓으신 부분이 있는데 아래와 같이 변경되어야 할 것 같습니다.

@Override
public boolean onActivityResult(int requestCode, int resultCode, Intent data) {
  Log.v(LOG_TAG, "onActivityResult requestCode: " + requestCode + " resultCode: " + resultCode + " data: " + data);
  if (Session.getCurrentSession().handleActivityResult(requestCode, resultCode, data)){
    return true; // 이부분 변경
  }
  return false;
}

문서를 봐보시면 아시겠지만 onActivityResult가 handle이 되었을때 true 를 반환해야합니다.

boolean onActivityResult(int requestCode,
                         int resultCode,
                         Intent data)
Returns:
true if the result has been handled.

Is there any plan in migrating to null-safety for Flutter 2.0.0?

Here's a kind guide about migrating. (dart.dev)

Thanks for that great flutter plugin
I'm trying to set it up for iOS and I have that error message after accepting kakao login

Any idea what causing this error?
Thanks!

KakaoLoginResult result = await kakaoSignIn.logIn();
final KakaoAccountResult account = result.account;

를 하였을 때, account.userID를 제외한 모든 값들이 null입니다..

혹시 추가적으로 설정해야 할 부분이 있을까요??
#15

가이드대로 모든 절차를 다 했는데도
logIn() 함수 호출 시 아래와 같은 에러가 발생합니다.

테스트 단말은 안드로이드구요

빠진 설정이 있을까요?

Google Play 에 배포하기 전 로컬 버전에서는 카카오톡앱을 통한 인증 후에 잘 진행이 됩니다.
하지만 배포한 후에 해당 버전을 Play Store 를 통해 설치하면 카카오톡 앱을 통해 인증한 후에 반환을 받지 못하는 것인지 진행이 안됩니다.
카카오톡 앱이 없는 경우 인증을 위한 카카오톡 로그인 페이지로 넘어가는데 이런 경우에는 인증이 진행됩니다.
이 부분 혹시 챙겨서 업데이트하실 수 있을까요?

관련 버전 정보도 추가합니다.

please help me. ;(

After retrieving access token via final KakaoAccessToken accessToken = await (kakaoSignIn.currentAccessToken); ... I check it at https://kapi.kakao.com/v2/user/me and the response is "this access token does not exist"

What can be the reason?

이게 제 문제인지 모르겠는데, 카카오 연동만 시키면 로그인 하는 순간 화면이 한번 더 나타나는데 원래 그런건가요?

Do i need to add the KakaoSDK Library to Frameworks?

@JosephNK when click on continue button I am not getting any response from Kakao and I am stuck on this page, I tried different accounts but same problem

NOTE:-- If KakaoTalk app installed in my device this page wont show up and I directly login with my KakaoTalk app it's only works on android version 10 or lower wont works on android version 11

@JosephNK please let me know how to fix this problem, have a nice day.

i got issue with https://pub.dev/packages/multi_image_picker and flutter_kakao_login.
the function onActivityResult in multi_image_picker override so that function in flutter_kakao_login not working and that make crash app in android.

좋은 라이브러리 만들어 주셔서 감사합니다. 카카오 인증서 이슈에 대해 말씀드릴 내용이 있습니다.

신뢰의 고리 문제로 인해, 애플이 카카오가 사용하고 있는 시만텍 발 인증서를 루트 저장소에서 삭제할 예정입니다. 이에 따라 카카오는 자사 도메인 일부의 SSL 인증서를 변경하기로 결정했습니다. 영향을 받는 도메인은 다음과 같습니다:

• kauth.kaka.com
• kapi.kakao.com
• dapi.kakao.com

카카오는 2021/10/1에 인증서를 교체할 예정입니다. 이후 지원되는 카카오 SDK 버전은 다음과 같습니다:

• iOS SDK 2.x
• Android SDK 2.7.0+

문제가 되는 부분이 있는지 확인 부탁드립니다. 감사합니다!

본 이슈에 대한 최대한 많은 유저의 접근성을 위해, 영어로 다시 질문을 첨부하겠습니다.

Thank you for creating a great library! I want to discuss Kakao's recent certificate issue.

Due to a chain of trust problem, Apple will delete Symantec certificate Kakao corp is currently using, so Kakao corp will substitute their domains' SSL certificate. Following domains will be effected:

kauth.kakao.com
kapi.kakao.com
dapi.kakao.com
They will change the certificate on 10/1/2021. And here's the supported Kakao SDK version after then:

iOS SDK 2.x
Android SDK 2.7.0+
Please check if there would be an issue. Thank you!

좋은 package 제작 감사합니다
잘 작동하네요

로그인 후 토큰을 서버로 보내 인증이 필요한데
토큰을 가져올수있도록 구현을 해 두시고
관련 안내가 없네요

var accessToken = (await kakaoSignIn.currentAccessToken).token;

이렇게 진행하면 맞나요

First of all thank you @JosephNK for creating this, I find it much better than the other package out there since it's much easier to use 👍

My issue is that final KakaoLoginResult result = await kakaoSignIn.getUserMe(); returns null except for userId.

When I debugged kakaoSignIn.getUserMe() method, the result seems to be there.

login_page.dart

final KakaoLoginResult result = await kakaoSignIn.getUserMe();
print('userName: ${result.account.userNickname}');

flutter: userNickname: null

flutter_kakao_login.dart

// Get UserMe Method
Future<KakaoLoginResult> getUserMe() async {
    final Map<dynamic, dynamic> result =
        await _channel.invokeMethod('getUserMe');

        print('debug: ${result.toString()}');

        return _delayedToResult(
            new KakaoLoginResult._(result.cast<String, dynamic>()));
 }

flutter: debug: {status: loggedIn, userID: xxxxxxxxxx, userNickname: xxxxxxxx}

Not sure why it won't return the value.

when we login in kakao and get KakaoAccountResult, there is only name and id , we are getting mail and proifle blank , even if we have that in our kakao account.

Please help
