使用hardware_buttons包（https://pub.dev/packages/hardware_buttons）应该很容易实现，它允许你在Flutter应用中监听硬件按钮事件。
由于耳机上的硬件按钮触发与手机甚至键盘上的按钮相同的事件，所以这应该是可能的：
void _listenToHardwareButtons() {
hardwareButtons.volumeButtonEvents.listen((event) {
if (event == hardwareButtons.VolumeButtonEvent.VOLUME_UP) {
print('耳机上的音量增加按钮被按下');
} else if (event == hardwareButtons.VolumeButtonEvent.VOLUME_DOWN) {
print('耳机上的音量减小按钮被按下');
}
});
}
你可能需要在androidmanifest.xml中添加所需的权限以监听硬件按钮事件，但出乎意料的是，我并不需要这样做。
现在这应该也可以在iOS上工作，但我无法尝试，因为我目前没有iPhone。
如果你只想监听音量键，你可以查看：https://pub.dev/packages/volume_watcher
对于桌面/网络应用：###
你可以使用Focus widget或RawKeyboardListener widget来监听键盘事件：
Focus(
autofocus: true,
focusNode: FocusNode(),
onKeyEvent: (node, event) {
if (event.physicalKey == PhysicalKeyboardKey.audioVolumeUp) {
return KeyEventResult.handled;
}
return KeyEventResult.ignored;
},
child: Container(),
),
英文:
It should be easily possible with the hardware_buttons package (https://pub.dev/packages/hardware_buttons), which allows you to listen to hardware button events in your Flutter app.
Since the Hardwarebuttons on a headset fire the same event as the buttons on your phone or even keyboard this should be possible:
void _listenToHardwareButtons() {
hardwareButtons.volumeButtonEvents.listen((event) {
if (event == hardwareButtons.VolumeButtonEvent.VOLUME_UP) {
print('Volume Up button pressed on headset');
} else if (event == hardwareButtons.VolumeButtonEvent.VOLUME_DOWN) {
print('Volume Down button pressed on headset');
}
});
}
You might need to add the required permissions for listening to hardware button-events in the androidmanifest.xml. I did not need to surprisingly.
This should even work on iOS now. But i could not try this out since i don't have an iPhone with me currently.
If you only want to listen to the VolumeKeys you might want to check out: https://pub.dev/packages/volume_watcher
For Desktop/Web:
You can use Focus widget or RawKeyboardListener widget to listen to keyboard events:
Focus(
autofocus: true,
focusNode: FocusNode(),
onKeyEvent: (node, event) {
if (event.physicalKey == PhysicalKeyboardKey.audioVolumeUp) {
return KeyEventResult.handled;
}
return KeyEventResult.ignored;
},
child: Container(),
),
