Flutter_facebook_login: App Crashes On launch with The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first

[kotlincodes]

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.

Error Log

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)

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 with static final FacebookLogin facebookSignIn = new FacebookLogin(); method.

I have browsed a lot but I am not able to solve out this issue.

I am Using the latest version of the plugin.

Issue will be solved with flutter clean

Flutter clean doesn't work for me. I hope the error message from this plugin and facebook could had been more detailed for troubleshooting purposes.

flutter clean isn't solving. Any ideas?

I had this error as well, thought this should have been called. After looking into it more, sdkInitialized is deprecated, and as far as I can tell facebook api will call it on it's own, assuming you have defined meta-data with key "com.facebook.sdk.ApplicationId", and a non empty value.

In my case, I provided a value from a string, created a string value for debug and release directories, and left the main one empty. Now I just moved my release values to the main, and left my debug values at their place and it's working.

Has anyone been able to solve this? flutter clean does not work for me either.

You should be write bellow code in MainActivity.kt

super.onCreate(savedInstanceState)
FacebookSdk.setApplicationId(getString(R.string.facebook_app_id))
FacebookSdk.sdkInitialize(getApplicationContext());
