Navigation through volume physical keys

The app uses a cross-platform framework, making it difficult to implement platform-specific features. I won't add support for this unless there's a well-maintained package that handles hardware physical buttons.

There are actually two packages in the wild that can do this:

• https://github.com/meetleev/flutter_volume_key_board (last commit 7 months ago)
• https://github.com/dart-tools/flutter_android_volume_keydown (last commit 2 years ago)

There aren't any well-maintained packages for now, but the existing ones seem to do the trick.

I've been burnt way too many times in the past by abandoned packages so I will just wait for a better one.
