[agrawalharsh90]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Flutter Facebook App Events gives the error: kotlin.UninitializedPropertyAccessException: lateinit property appEventsLogger has not been initialized

I am using the latest version of FaceBook App Events plugin in Flutter with the latest version of Flutter as well. On click event, I am calling the logEvent method like this:

facebookAppEvents.logEvent(
    name: 'Link Clicked',
    parameters: {'url': request.url},
);

where the facebookAppEvents defined and initialized in the class itself:

static final facebookAppEvents = FacebookAppEvents();

Expected Behavior

It should properly log the event the properly without any error.

Steps To Reproduce

[DennisAlund]

I find 8 results when searching issues for "sdk initialized" please search, read and see if it is already discussed and solved

[agrawalharsh90]

@DennisAlund no solution is in any of the issue,
There is one issue that has exact same problem but no solution is present in it.
#186

Can you please provide me the solution as to solve this?

[DennisAlund]

Seems to be a configuration error by the user since the OP of #186 closed his own issue. I don't know what the solution was since he reported problem but closed it himself.

My assumption would be that he had misconfigured the setup. There was no explanation afterwards what he had missed. But if you find that you have a misconfiguration, I would really appreciate if you share with the community what it was and how you solved it.

But from my side, I can't reproduce it.

Have you tried comparing your project with the example project in the repo?

[AbdulrazakZakieh]

I am facing the same problem and I did all the configurations as instructed. setAdvertiserTracking is working but events are not.
I searched for similar problems but found none and all the issues you mentioned are irrelevant as I see it.

not put id here manifest like this

        <meta-data
            android:name="com.facebook.sdk.ApplicationId"
            android:value="xxxxxxxxxx" />

add like this

        <meta-data
            android:name="com.facebook.sdk.ApplicationId"
            android:value="@string/facebook_app_id" />

create strings.xml file in android/app/src/main/res/values/ and put id here

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="facebook_app_id">xxxxxxxxxx</string>
</resources>

After adding <string name="facebook_client_token">YOUR_TOKEN</string> it's working

I have the same problem.

[Ahmedklai]

So the solution was basically to put the :
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/> <meta-data android:name="com.facebook.sdk.ClientToken" android:value="@string/facebook_client_token"/>

in the right spot , they need to be under the application Tag , in the first range so not under appliction and then activity tag just under the application tag in the androidManifest just as in the pic below !
