A problem occurred evaluating project tflite

I tried to use the tflite package to create a live object detection app, but it seems that after I installed both the packages: tflite, and also wrote the detection code it didn't seem to run.

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':tflite'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
   > Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

     If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

* 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.

This issue occurs because the library is not updated for three years. To fix this you can try out this PR.

If not solved than have a look in the GitHub repo and PR section, which will be really helpful because of the contributors.
