Facebook Login Integration With Flutter
Solution 1
The issue is solved. Just need to run flutter clean
and re run the project.
Solution 2
The plugin you mentioned is correct. I guess you have missed initializing the SDK according to the Error log.
I will recommend you to follow the steps from the below-mentioned tutorial written by Rohan Taneja.

I am trying to integrate facebook login with Flutter using the instructions provided here for android.
I think it is a official plugin , I have followed everything in this documentation but I am getting the following error and app crashes on Launch.
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.shrishtionline.quikpayagent/com.shrishtionline.quikpayagent.MainActivity}: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first. at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2724) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2789) at android.app.ActivityThread.-wrap12(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1527) at android.os.Handler.dispatchMessage(Handler.java:110) at android.os.Looper.loop(Looper.java:203) at android.app.ActivityThread.main(ActivityThread.java:6251) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1075) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:936) Caused by: The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first. at com.facebook.internal.Validate.sdkInitialized(Validate.java:143) at com.facebook.login.LoginManager.<init>(LoginManager.java:79) at com.facebook.login.LoginManager.getInstance(LoginManager.java:92) at com.roughike.facebooklogin.facebooklogin.FacebookLoginPlugin$FacebookSignInDelegate.<init>(FacebookLoginPlugin.java:109) at com.roughike.facebooklogin.facebooklogin.FacebookLoginPlugin.<init>(FacebookLoginPlugin.java:38) at com.roughike.facebooklogin.facebooklogin.FacebookLoginPlugin.registerWith(FacebookLoginPlugin.java:42) at io.flutter.plugins.GeneratedPluginRegistrant.registerWith(GeneratedPluginRegistrant.java:23) at com.shrishtionline.quikpayagent.MainActivity.onCreate(MainActivity.java:11) at android.app.Activity.performCreate(Activity.java:6666) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1118) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2677)
I have integrated google sign-in for both IOS and Android but I got stuck here in facebook login.
The error log says to call
FacebookSdk.sdkInitialize()
, But in dart I am not able to call this code. But I have initialized Facebook SDK withstatic final FacebookLogin facebookSignIn = new FacebookLogin();
method.I have browsed a lot but I am not able to solve out this issue.
