To apply a set of keyboard shortcuts to a large section of the tree, use the Shortcuts widget:
// Define a class for each type of shortcut action you want
class CreateNewItemIntent extends Intent {
const CreateNewItemIntent();
}
Widget build(BuildContext context) {
return Shortcuts(
// Bind intents to key combinations
shortcuts: const <ShortcutActivator, Intent>{
SingleActivator(LogicalKeyboardKey.keyN, control: true):
CreateNewItemIntent(),
},
child: Actions(
// Bind intents to an actual method in your code
actions: <Type, Action<Intent>>{
CreateNewItemIntent: CallbackAction<CreateNewItemIntent>(
onInvoke: (intent) => _createNewItem(),
),
},
// Your sub-tree must be wrapped in a focusNode, so it can take focus.
child: Focus(
autofocus: true,
child: Container(),
),
),
);
}
The Shortcuts widget is useful because it only allows shortcuts to be fired when this widget tree or one of its children has focus and is visible.
