flutter_android_volume_keydown

A simple flutter plugin for Android that listens to the volume up down button. It blocks the buttons from changing 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) {
      if (event == HardwareButton.volume_down) {
        print("Volume down received");
      } else if (event == HardwareButton.volume_up) {
        print("Volume up received");
      }
    });

To stop listening:

subscription?.cancel();

While listening the Volume button events are not handled by Android, when you stop listening the buttons resume their normal functionality again.
