If true, this widget may request the primary focus.
Defaults to true. Set to false if you want the FocusNode this widget manages to do nothing when FocusNode.requestFocus is called on it. Does not affect the children of this node, and FocusNode.hasFocus can still return true if this node is the ancestor of the primary focus.
This is different than Focus.skipTraversal because Focus.skipTraversal still allows the widget to be focused, just not traversed to.
Setting FocusNode.canRequestFocus to false implies that the widget will also be skipped for traversal purposes.
- FocusTraversalGroup, a widget that sets the traversal policy for its descendants.
- FocusTraversalPolicy, a class that can be extended to describe a traversal policy.
bool get canRequestFocus => _canRequestFocus ?? focusNode?.canRequestFocus ?? true;
