Question

How do I access the variable "selectedTag" from this statefulWidget:

class _AlertDialogOneState extends State<AlertDialogOne> {
  Item selectedTag;
...
  }
}

inside this statelessWidget :

class CardTile extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(...

class CardTile extends StatelessWidget {
  final Item selectedTag;// Add this
  CardTile(this.selectedTag); // Add this

  @override
  Widget build(BuildContext context) {
    return Container(...
