class HomeScreen extends StatefulWidget {

  @override
  State<HomeScreen> createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {
  final LinkedInConfig _linkedInConfig = LinkedInConfig(
      clientId: 'YOUR_CLIENT_ID', // Replace with your LinkedIn client ID
      clientSecret: 'YOUR_CLIENT_SECRET', // Replace with your LinkedIn client secret
      redirectUrl: 'YOUR_REDIRECT_URL'); // Replace with your LinkedIn redirect URL

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        body: Center(
            child: ElevatedButton(
                onPressed: () async {
                  await LinkedinSigninPlus.signInWithLinkedin(context,
                      config: _linkedInConfig, 
                      onGetAuthToken: (token) {
                        inspect(token); // Inspect or use the token as needed
                      }, 
                      onGetUserProfile: (user) {
                        inspect(user); // Inspect or use user profile data
                      });
                },
                child: const Text('Sign in with LinkedIn'))));
  }
}

Explanation

  • LinkedInConfig: Configure your plugin with clientId, clientSecret, and redirectUrl obtained from the LinkedIn Developer Console.
  • signInWithLinkedin(): This function handles the authentication process. It takes a context and a configuration object.
    • onGetAuthToken: Callback function that provides the authentication token.
    • onGetUserProfile: Callback function that provides the user's LinkedIn profile details.

Replace the placeholders (YOUR_CLIENT_ID, YOUR_CLIENT_SECRET, YOUR_REDIRECT_URL) with the actual credentials from your LinkedIn app configuration.
