flutter_naver_login
A Flutter plugin for using the native Naver Login SDKs on Android and iOS.
AndroidX support
Installation
To get things up and running, you'll have to declare a pubspec dependency in your Flutter project. Also some minimal Android & iOS specific configuration must be done, otherise your app will crash.
On your Flutter project
See the installation instructions on pub.
Android
This assume that you have performed the "link app to package name and base class the Naver Login documentation for Android site.
Your Application Info is shown in the for Naver Developer Website.
Then find out what the Client ID is. The Naver Client ID can be found on the Naver App Dashboard from the Naver Developer Console.
Once you find out your Naver Client ID, URL Scheme and Set Package Name you'll have to do some things.
Then simply copy and paste into ROOT.

It is also necessary to uses FlutterFragmentActivity instead of FlutterActivity since uses of naver sdk 5.4.0.

iOS
\
pod installThis assumes that you've done the "Register and Configure Your App with Naver" step in the the Naver Login documentation for iOS site. (Note: you can skip "Step 2: Set up Your Development Environment").
After you've done that, find out what your Naver App Client ID is. You can find your Client ID, Client Secret, URL_SCHEME, in your Naver App's dashboard in the Naver developer.

}if you use xcode version is over 10
- When FlutterNaverLogin.logIn() doesn't return anything. if your Naver Social Login works in Android and ios(Naver app is not installed). Especially if you already face this error with modifing "AppDelegate.swift". Then you should check xcode version.
Swift Compiler Error (Xcode): 'UIApplicationOpenURLOptionsKey' has been renamed to 'UIApplication.OpenURLOptionsKey'import NaverThirdPartyLogin
override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool { var applicationResult = false if (!applicationResult) { applicationResult = NaverThirdPartyLoginConnection.getSharedInstance().application(app, open: url, options: options) } // if you use other application url process, please add code here.
if (!applicationResult) {
applicationResult = super.application(app, open: url, options: options)
}
return applicationResult}
## How do I use it?
The library tries to closely match the native Android & iOS login SDK APIs where possible. For complete API documentation, just see the [source code](). Everything is documented there.
Since sample code is worth more than one page of documentation, here are the usual cases covered:
### Getting the Naver acccount of a signed in user
```dart
NaverLoginResult res = await FlutterNaverLogin.logIn();
setState(() {
name = res.account.name;
});The account variable will now contain the following information:
final String nickname;
final String id;
final String name;
final String email;
final String gender;
final String age;
final String birthday;
final String birthyear;
final String profileImage;
final String mobile;
final String mobileE164;Getting the Naver currentAccessToken of a signed in user
import 'package:flutter_naver_login/flutter_naver_login.dart';
NaverLoginResult res = await FlutterNaverLogin.logIn();
final NaverLoginResult result = await FlutterNaverLogin.logIn();
NaverAccessToken res = await FlutterNaverLogin.currentAccessToken;
setState(() {
accesToken = res.accessToken;
tokenType = res.tokenType;
});ios issue
- CocoaPods could not find compatible versions for pod "naveridlogin-sdk-ios" Specs satisfying the
naveridlogin-sdk-ios (~> 4.0.12)dependency were found, but they required a higher minimum deployment target.- runner target - required a higher deployment target 10.0.
