Features #

To be added...

Android specification #

If you subscribe to volume button events, this plugin will inevitably request for ACTION_MANAGER_OVERLAY_PERMISSION, since we found out this was the only way to do it well in Flutter Plugin environment. We do show permission request window for you, so there's nothing you should do other than subscribing to the event channel. However, since users may be surprised why your app needs this permission, we suggest notifying users beforehand why this permission will be requested.
Migrated to AndroidX as of version 1.0.0. To use with original support libraries, use version 0.2.4. Note, however, pre-AndroidX will no longer be supported.

iOS specification #

No VOLUME_DOWN events are emitted when the volume is already at its minimum. VOLUME_UP events vice versa. On the other hand, events always occur whenever user presses the button on Android.

Usage #
Import the package #
To use this plugin, follow the plugin installation instructions.
To use with AndroidX, install the latest version as above instructions. To use with original support libraries, install version 0.2.4 instead.
Use the plugin #
Add the following import to your Dart code:
import 'package:hardware_buttons/hardware_buttons.dart';
copied to clipboard
In order to listen to volume button events, use volumeButtonEvents.listen as below:
StreamSubscription _volumeButtonSubscription;

@override
void initState() {
super.initState();
_volumeButtonSubscription = volumeButtonEvents.listen((VolumeButtonEvent event) {
// do something
// event is either VolumeButtonEvent.VOLUME_UP or VolumeButtonEvent.VOLUME_DOWN
});
}

@override
void dispose() {
super.dispose();
// be sure to cancel on dispose
_volumeButtonSubscription?.cancel();
}
copied to clipboard
Besides volume button events, there are also:

Home button events, via homeButtonEvents.listen.
Lock button events, via lockButtonEvents.listen.
