flutter_android_volume_keydown

A simple flutter plugin for Android that listens to the volume down button. It blocks the button from lowering the volume while listening for events.

How to use

Using the plugin is very simple:

• Add flutter_android_volume_keydown to your pubspec.yaml
• Change your MainActivity.java or MainActivity.kt to extend FlutterAndroidVolumeKeydownActivity
• Implement a simple listener:

var subscription = FlutterAndroidVolumeKeydown.stream.listen((event) {
      print("Volume Keydown received");
    });

To stop listening:

subscription?.cancel();

While listening the Volume Keydown events are not handled by Android, when you stop listening the button resumes its normal functionality again.
