Methods

addEarlyKeyEventHandler(OnKeyEventCallback handler) → void
Adds a key event handler to a set of handlers that are called before any key event handlers in the focus tree are called.
inherited
addHighlightModeListener(ValueChanged<FocusHighlightMode> listener) → void
Register a closure to be called when the FocusManager notifies its listeners that the value of highlightMode has changed.
inherited
addLateKeyEventHandler(OnKeyEventCallback handler) → void
Adds a key event handler to a set of handlers that are called if none of the key event handlers in the focus tree handle the event.
inherited
addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
applyFocusChangesIfNeeded() → void
Applies any pending focus changes and notifies listeners that the focus has changed.
inherited
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
dispose() → Future<void>
Do super.dispose and close all the streams.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
registerGlobalHandlers() → void
Registers global input event handlers that are needed to manage focus.
inherited
removeEarlyKeyEventHandler(OnKeyEventCallback handler) → void
Removes a key handler added by calling addEarlyKeyEventHandler.
inherited
removeHighlightModeListener(ValueChanged<FocusHighlightMode> listener) → void
Remove a previously registered closure from the list of closures that the FocusManager notifies.
inherited
removeLateKeyEventHandler(OnKeyEventCallback handler) → void
Removes a key handler added by calling addLateKeyEventHandler.
inherited
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
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
