findFirstFocus method
Returns the node that should receive focus if focus is traversing forwards, and there is no current focus.
The node returned is the node that should receive focus if focus is
traversing forwards (i.e. with next), and there is no current focus in
the nearest FocusScopeNode that currentNode belongs to.
If ignoreCurrentFocus is false or not given, this function returns the
FocusScopeNode.focusedChild, if set, on the nearest scope of the
currentNode, otherwise, returns the first node from sortDescendants,
or the given currentNode if there are no descendants.
If ignoreCurrentFocus is true, then the algorithm returns the first node
from sortDescendants, or the given currentNode if there are no
descendants.

Implementation
FocusNode? findFirstFocus(FocusNode currentNode, {bool ignoreCurrentFocus = false}) {
return _findInitialFocus(currentNode, ignoreCurrentFocus: ignoreCurrentFocus);
