AlwaysDisabledFocusNode()

Properties

ancestors Iterable<FocusNode>
An Iterable over the ancestors of this node. [...]
read-only, inherited
canRequestFocus bool
If true, this focus node may request the primary focus. [...]
@mustCallSuper, read / write, inherited
children Iterable<FocusNode>
An iterator over the children of this node.
read-only, inherited
context BuildContext?
The context that was supplied to attach. [...]
read-only, inherited
debugLabel String?
A debug label that is used for diagnostic output. [...]
read / write, inherited
descendants Iterable<FocusNode>
An Iterable over the hierarchy of children below this one, in depth-first order.
read-only, inherited
descendantsAreFocusable bool
If false, will disable focus for all of this node's descendants. [...]
@mustCallSuper, read / write, inherited
enclosingScope FocusScopeNode?
Returns the nearest enclosing scope node above this node, or null if the node has not yet be added to the focus tree. [...]
read-only, inherited
hasFocus bool
Whether this node has input focus. [...]
read-only, override
hashCode int
The hash code for this object. [...]
read-only, inherited
hasListeners bool
Whether any listeners are currently registered. [...]
@protected, read-only, inherited
hasPrimaryFocus bool
Returns true if this node currently has the application-wide input focus. [...]
read-only, inherited
highlightMode FocusHighlightMode
Returns the FocusHighlightMode that is currently in effect for this node.
read-only, inherited
nearestScope FocusScopeNode?
Returns the nearest enclosing scope node above this node, including this node, if it's a scope. [...]
read-only, inherited
offset Offset
Returns the global offset to the upper left corner of the attached widget's RenderObject, in logical units. [...]
read-only, inherited
onKey FocusOnKeyCallback?
Called if this focus node receives a key event while focused (i.e. when hasFocus returns true). [...]
read / write, inherited
onKeyEvent FocusOnKeyEventCallback?
Called if this focus node receives a key event while focused (i.e. when hasFocus returns true). [...]
read / write, inherited
parent FocusNode?
Returns the parent node for this object. [...]
read-only, inherited
rect Rect
Returns the global rectangle of the attached widget's RenderObject, in logical units. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
size Size
Returns the size of the attached widget's RenderObject, in logical units. [...]
read-only, inherited
skipTraversal bool
If true, tells the focus traversal policy to skip over this node for purposes of the traversal algorithm. [...]
read / write, inherited
traversalChildren Iterable<FocusNode>
An iterator over the children that are allowed to be traversed by the FocusTraversalPolicy.
read-only, inherited
traversalDescendants Iterable<FocusNode>
Returns all descendants which do not have the skipTraversal and do have the canRequestFocus flag set.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes. [...]
inherited
attach(BuildContext? context, {FocusOnKeyEventCallback? onKeyEvent, FocusOnKeyCallback? onKey}) FocusAttachment
Called by the host StatefulWidget to attach a FocusNode to the widget tree. [...]
@mustCallSuper, inherited
consumeKeyboardToken() bool
Removes the keyboard token from this focus node if it has one. [...]
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() → 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 and removeListener will throw after the object is disposed). [...]
inherited
focusInDirection(TraversalDirection direction) bool
Request to move the focus to the nearest focus node in the given direction, by calling the FocusTraversalPolicy.inDirection method. [...]
inherited
nextFocus() bool
Request to move the focus to the next focus node, by calling the FocusTraversalPolicy.next method. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
notifyListeners() → void
Call all the registered listeners. [...]
previousFocus() bool
Request to move the focus to the previous focus node, by calling the FocusTraversalPolicy.previous method. [...]
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes. [...]
inherited
requestFocus([FocusNode? node]) → void
Requests the primary focus for this node, or for a supplied node, which will also give focus to its ancestors. [...]
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. [...]
inherited
unfocus({UnfocusDisposition disposition = UnfocusDisposition.scope}) → void
Removes the focus on this node by moving the primary focus to another node. [...]
inherited

Operators

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