Create a recipe to demonstrate the new Cupertino-Sheet class

[sfshaza2]

What information needs to be added?

This feature was added for for the next stable release.

Where should this new content appear?

/cookbook/design/sheets ??
/cookbook/design/cupertino ??

I would like to fix this problem.

• I will try and fix this problem on docs.flutter.dev.

In the simple case it's very easy, similar to showMenu etc.

CupertinoButton.filled(
              onPressed: () {
                showCupertinoSheet<void>(
                  context: context,
                  useNestedNavigation: true,
                  pageBuilder: (BuildContext context) => const _SheetScaffold(),
                );
              },
              child: const Text('Open Bottom Sheet'),
            ),
