AutocompleteHighlightedOptionModifier class
An inherited widget used to indicate which autocomplete option should be highlighted for keyboard navigation.
The RawAutoComplete widget will wrap the options view generated by the
optionsViewBuilder with this widget to provide the highlighted option's
index to the builder.
In the builder callback the index of the highlighted option can be obtained
by using the static of method:
final highlightedIndex = AutocompleteHighlightedOption.of(context);
which can then be used to tell which option should be given a visual indication that will be the option selected with the keyboard.
