Build error after upgrading to gradle 8.5 and AGP to 8.3.2

After updating to Android Studio Ladybug | 2024.2.1 Patch 2
Build #AI-242.23339.11.2421.12550806, built on October 24, 2024
and flutter and dart plugins I had to update gradle version, I followed [this](https://stackoverflow.com/a/79067192/13521429) answer but then started getting this error:

```
FAILURE: Build failed with an exception.

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

BUILD FAILED in 10s
Error: Gradle task assembleDebug failed with exit code 1
```

The failure is in the :flutter_vision module; start by inspecting that module's Android build file and its source AndroidManifest.xml, both referenced by the error. Check the namespace migration guidance, then rerun assembleDebug and confirm the package builds without the namespace error.
