A problem occurred configuring project ':system_settings'.

Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
Namespace not specified. Please specify a namespace in the module's build.gradle file like so:

 android {
     namespace 'com.example.namespace'
 }

It's been 2.5 years since the last commit, it might be dead or forgotten.

Here are some alternatives:
https://pub.dev/packages/app_settings <- I switched to this one
https://pub.dev/packages/open_settings_plus

Yeah, I sadly had the feeling it would x)

Funny enough, I found those two as well when looking for alternatives. Thanks for letting me know that the first one you mentioned (app_settings) is working :)
