为了实现此行为，您可以用小部件包装页面内容或任何特定小部件KeyboardListener，并将其配置为监听Alt与左箭头键 ( Alt + BackArrow) 组合的键。以下是示例：
KeyboardListener(
autofocus: true, // Ensures the widget is ready to listen to keyboard events without requiring focus
focusNode: FocusNode(), // A focus node to manage focus on this widget
onKeyEvent: (event) {
// Check if the Alt key is pressed (HardwareKeyboard.instance.isAltPressed) and the left arrow key is pressed (event.logicalKey == LogicalKeyboardKey.arrowLeft) at the same time, and if it’s a key down event (event is KeyDownEvent)
if (HardwareKeyboard.instance.isAltPressed &&
event.logicalKey == LogicalKeyboardKey.arrowLeft &&
event is KeyDownEvent) {
Navigator.of(context).pop(); // Pop the current page from the navigation stack
}
},
child: MyWidget(), // Replace 'MyWidget' with your actual page or widget content
)
