Error: Method 'readState' cannot be called on 'PageStorageBucket?' because it is potentially null

[xAlstrat]

I'm using Flutter 3.3.8v

Full error is:

../../development/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_carousel_widget-2.0.2/lib/src/_flutter_carousel_widget.dart:368:22: Error: Method 'readState' cannot be called on 'PageStorageBucket?' because it is potentially null.
 - 'PageStorageBucket' is from 'package:flutter/src/widgets/page_storage.dart' ('../../development/flutter/packages/flutter/lib/src/widgets/page_storage.dart').
Try calling using ?. instead.
                    .readState(storageContext) as double?;
                     ^^^^^^^^^

Looks like the solution is easy, but not sure if compatible with older versions of flutter.

Hey,

Thanks
