I keep getting an error when trying to run on an Android Simulator. I have firebasecore and Square in app payments in this app. This is the error:
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':package_info_plus'.
> 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'
}
If the package attribute is specified in the source AndroidManifest.xml, it can be migrated automatically to the namespace value in the build.gradle file using the AGP Upgrade Assistant; please refer to https://developer.android.com/studio/build/agp-upgrade-assistant for more information.

This is what I have done so far:

I have tried switching distributionUrl=https://services.gradle.org/distributions/gradle-8.1.1-bin.zip
to 7.6.1 but it did not work either. As you can see I’ve also assigned a namespace. What do you recommend I do?

The problem can be the version of Gradle, not all package support version 8.x.x yet.
I suggest you stay on version 7.
from experimentation, the problem is that ‘namespace’ needs to be specified in all modules, which includes ones from flutter packages..
coincidentally, i also had the same problem with package_info_plus.
with this SO thread, i managed to fix this specific error by adding this in the global build.grade:
