ShortcutManager class Null safety
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.

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

read-onlyinherited
- hasListeners → bool
- Whether any listeners are currently registered.

-
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.
final
- runtimeType → Type
-

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
override
-
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).
mustCallSuper">@mustCallSuperinherited
-
handleKeypress(
BuildContext context, RawKeyEvent event) → KeyEventResult -
Handles a key press
event
in the givencontext
.protected">@protected -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited
-
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.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(
{DiagnosticLevel minLevel = DiagnosticLevel.info}) → String -
A string representation of this object.
inherited
-
toStringShort(
) → String -
A brief description of this object, usually just the runtimeType and the
hashCode.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
