You can use this code according to your need. It works perfect.

 Future<bool?> showDeleteDialog(BuildContext context) async {
    return await showDialog<bool>(
      context: context,
      builder: (BuildContext context) {
        return AlertDialog(
          title: const Text('Delete Account'),
          content: const Text('Are you sure you want to delete your account?'),
          actions: <Widget>[
            TextButton(
              child: const Text('Cancel'),
              onPressed: () {
                Navigator.of(context).pop(false);
              },
            ),
            TextButton(
              child: const Text(
                'Delete',
                style: TextStyle(color: Colors.red),
              ),
              onPressed: () {
                Navigator.of(context).pop(true);
              },
            ),
          ],
        );
      },
    );
  }
