Not building with AGP8

[Ravensof]

Hello. can you update your lib to agp 8?

Launching lib\main.dart on sdk gphone64 x86 64 in debug mode...
Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':headset_connection_event'.
> 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.

You should add namespace to gradle.build like this

android {
  // Conditional for compatibility with AGP <4.2.
  if (project.android.hasProperty("namespace")) {
    namespace 'com.example.app'
  }
...
}

and remove manifest.package from AndroidManifest.xml
