Deprecated version of the Android embedding

[adityathakurxd]

Describe the bug
The plugin countdown_flutter uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are the plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

To Reproduce
Steps to reproduce the behavior:

1. Add the plugin to pubspec.yaml
2. Run flutter pub get
3. See error

Expected behavior
Should run pub get without warning.

Screenshots

Additional context
If you are the plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.
