You can list all files uploaded under a given path.

This will list all public files (i.e. those with `guest` access level):

```dart
Future<void> listItems() async {
  try {
    final result = await Amplify.Storage.list();
    final items = result.items;
    safePrint('Got items: $items');
  } on StorageException catch (e) {
    safePrint('Error listing items: $e');
  }
}
```
