          width: 40,
          color: Colors.green,

          recognizer: TapGestureRecognizer()
            ..onTap = () {
              showDialog<String>(
                context: context,
                builder: (BuildContext context) => AlertDialog(
                  title: const Text('AlertDialog Title'),
                  content: const Text('AlertDialog description'),
                  actions: <Widget>[
                    TextButton(
                      onPressed: () => Navigator.pop(context, 'Cancel'),
                      child: const Text('Cancel'),
                    ),
                    TextButton(
                      onPressed: () => Navigator.pop(context, 'OK'),
                      child: const Text('OK'),
                    ),
                  ],
                ),
              );
            }),
