Change dnd pacakges

[guyluz11]

It looks like there are some errors with the dnd package while running the app using the latest Flutter version

$ flutter --version
Flutter 3.27.1 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 17025dd882 (8 days ago) • 2024-12-17 03:23:09 +0900
Engine • revision cb4b5fff73
Tools • Dart 3.6.0 • DevTools 2.40.2

The error:

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

FAILURE: Build failed with an exception.

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

Error: Gradle task assembleDebug failed with exit code 1

We should consider moving to a different package like do_not_disturb
