optionGroups property

@override List<OptionGroup<T>> get optionGroups

The groups of available options.

Do not modify this list from outside of this class. Instead, create a SelectionOptions from a stream. This list may be replaced by the data provider, so consider this list reference to be ephemeral, with the SelectionOptions object's property as the source of truth.

Implementation

@override
List<OptionGroup<T>> get optionGroups => _filteredGroups ?? [];

@override set optionGroups (List<OptionGroup<T>> groups)

Implementation

@override
set optionGroups(List<OptionGroup<T>> groups) {
  _options.optionGroups = groups;
}
