CLDialog<T> class abstract

Base class for CL dialogs with title, optional subtitle, and confirm/cancel actions.

Subclasses implement buildContent to provide the dialog body. The onConfirm callback may be synchronous or asynchronous and its return value is used as the result passed to Navigator.pop.

Example:

class MyDialog extends CLDialog<String> {
  const MyDialog({super.key}) : super(title: 'Esempio');

  @override
  Widget buildContent(BuildContext context) => const Text('Body');
}
