Methods
-
addListener(VoidCallback listener)
→ void
-
Register a closure to be called when the object changes. [...]
inherited
-
attach(BuildContext context, { 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. [...]
@protected, @visibleForTesting, inherited
-
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.debug })
→ String
-
Returns a string representation of this object.
inherited
-
toStringDeep({String prefixLineOne: '', String prefixOtherLines, DiagnosticLevel minLevel: DiagnosticLevel.debug })

-
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()
→ void
-
Removes focus from a node that has the primary focus, and cancels any
outstanding requests to focus it. [...]
