flutter facebook_app_events cannot load dependency for Android

Question

I am working on a Flutter App that contains the dependency facebook_app_events. It's been working completely fine so far, but now, out of NOTHING, stopped working for android.

When I build the app I get the following error:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:checkProdDebugAarMetadata'.
> Could not resolve all files for configuration ':app:prodDebugRuntimeClasspath'.
   > Could not resolve com.facebook.android:facebook-android-sdk:15.+.
     Required by:
         project :app > project :facebook_app_events
      > Failed to list versions for com.facebook.android:facebook-android-sdk.
         > Unable to load Maven meta-data from https://jcenter.bintray.com/com/facebook/android/facebook-android-sdk/maven-metadata.xml.
            > Could not HEAD 'https://jcenter.bintray.com/com/facebook/android/facebook-android-sdk/maven-metadata.xml'.
               > Read timed out

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

task clean(type: Delete) {

}

I have been trying to figure this out for hours, and nothing has worked so far. I tried using another version of the dependency, adding the dependency manually in the app/build.gradle, using different flutter versions. Nothing worked.

It was JCenter which was down and causing an error while downloading the Facebook Android dependencies.

Your app should absolutely work fine in the iOS device/simulator If Android is still not working.

You can check the status of the Gradle here.
