flutter_linkedin_login

A Flutter plugin for Sign in with LinkedIn

IMPORTANT NOTICE

LinkedIn is discontinuing their mobile SDKs, which this plugin depends on. iOS 12 seems to already be not working anymore. The LinkedIn app, doesn't ask for 3rd party app permissions like it used to. Support will end March 2019. The fate of this plugin is undetermined. It may be redesigned to use LinkedIn's OAuth 2.0 APIs. Stay tuned. See [https://engineering.linkedin.com/blog/2018/12/developer-program-updates]

Installation

See the installation instructions on pub

Android

Follow the "Associate your Android app with your LinkedIn app" section of LinkedIn's Getting started with Android. Find your package name in the android/app/src/main/AndroidManifest.xml file. For the debug key hash value generation, remember to use 'android' as your password. Click update after adding your package and key in LinkedIn's developer console for your changes to take.

Open your MainActivity in your Android app/src/main/ directory and override the onActivityResult method with the following

import android.content.Intent
import io.tuantvu.flutterlinkedinlogin.FlutterLinkedinLoginPlugin

//kotlin
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
  FlutterLinkedinLoginPlugin.onActivityResult(this, requestCode, resultCode, data)
  super.onActivityResult(requestCode, resultCode, data)
}

import android.content.Intent
import io.tuantvu.flutterlinkedinlogin.FlutterLinkedinLoginPlugin

//java
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
  FlutterLinkedinLoginPlugin.onActivityResult(this, requestCode, resultCode, data);
  super.onActivityResult(requestCode, resultCode, data);
}

iOS

• May not work with iOS 12

Follow the "Associate your iOS app with your LinkedIn app" section of LinkedIn's Getting started with iOS.

Open your AppDelegate in your ios/Runner directory and add the following function

//swift
//add #import <flutter_linkedin_login/FlutterLinkedinLoginPlugin.h>
//to your Running-Bridging-Header.h file
override func application(_ app: UIApplication, open: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    if (FlutterLinkedinLoginPlugin.shouldHandle(open)) {
        return FlutterLinkedinLoginPlugin.application(app, open: open, sourceApplication: nil, annotation: nil)
    }
    return true
}

//objective-c
//add #import <flutter_linkedin_login/FlutterLinkedinLoginPlugin.h> at top of your AppDelegate.m
- (BOOL)application:(UIApplication *)application open:(NSURL *)open options:(UIApplicationOpenURLOptionsKey *)options {
    if ([FlutterLinkedinLoginPlugin shouldHandleUrl:url]) {
        return [FlutterLinkedinLoginPlugin application:application open:open sourceApplication:nil annotation: nil];
    }
    return YES;
}
