ShortcutManager class

A manager of keyboard shortcut bindings used by Shortcuts to handle key events.

The manager may be listened to (with addListener/removeListener) for change notifications when the shortcuts change.

Typically, a Shortcuts widget supplies its own manager, but in uncommon cases where overriding the usual shortcut manager behavior is desired, a subclassed ShortcutManager may be supplied.

Mixed in types


ShortcutManager({Map<ShortcutActivator, Intent> shortcuts = const <ShortcutActivator, Intent>{}, bool modal = false})
Constructs a ShortcutManager.


hashCode int
The hash code for this object.
no setterinherited
hasListeners bool
Whether any listeners are currently registered.
no setterinherited
True if the ShortcutManager should not pass on keys that it doesn't handle to any key-handling widgets that are ancestors to this one.
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
shortcuts Map<ShortcutActivator, Intent>
Returns the shortcut map.
getter/setter pair


addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
handleKeypress(BuildContext context, KeyEvent event) KeyEventResult
Handles a key press event in the given context.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
notifyListeners() → void
Call all the registered listeners.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
toString({DiagnosticLevel minLevel =}) String
A string representation of this object.
toStringShort() String
A brief description of this object, usually just the runtimeType and the hashCode.


operator ==(Object other) bool
The equality operator.
