findFirstFocus method Null safety

FocusNode? findFirstFocus(
  1. FocusNode currentNode,
  2. {bool ignoreCurrentFocus = false}
)

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.

The currentNode argument must not be null.

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.
