Simple Usage #

Creating a basic SimpleGroupedCheckbox

Declare GroupController to get selection and enabled/disabled Items #

GroupController controller = GroupController();

GroupController

PropertiesDescription
isMultipleSelection(bool) enable multiple selection in grouped checkbox (default:false).
initSelectedItem(List) A Initialize list of values that will be selected in grouped.

final selectedItems = controller.selectedItem;

enable items #

    controller.enableAll();

disable all items #

    controller.disableAll();

enabled items #

controller.enabledItemsByValues(List<T> values); 

controller.enabledItemsByTitles(List<String> itemsTitles); 

disable item #

controller.disabledItemsByValues(List<T> values);
controller.disabledItemsByTitles(List<String> items)

listener to changed values #

listener will be removed automatically when widget call dispose

controller.listen((v) {
      print("$v");
    });
