Null Safety issue

Throws this error due to WidgetsBinding being nullable:

/C:/SDKs/flutter/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_screenutil-5.5.3/lib/src/screen_util.dart:104:29: Error: Method 'addPostFrameCallback' cannot be called on 'WidgetsBinding?' because it is potentially null.
- 'WidgetsBinding' is from 'package:flutter/src/widgets/binding.dart' ('/C:/SDKs/flutter/flutter/packages/flutter/lib/src/widgets/binding.dart').
package:flutter/…/widgets/binding.dart:1
Try calling using ?. instead.
    WidgetsBinding.instance.addPostFrameCallback((_) {
                            ^^^^^^^^^^^^^^^^^^^^

Can we update this with the nullish access operator? Or a non-null assertion, if we're sure WidgetsBinding is initialized.

Thank you, I didn't pay attention to that. In Flutter SDK 3.0.0, WidgetsBinding.instance wouldn't return nullable anymore, that's why I didn't get an error.
