currently im using flutter web 3.0 . when i upgraded to this flutter version , i got this error on my consol 👍

/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/adaptive_theme-2.3.1/lib/src/adaptive_theme.dart:218:20: Warning: Operand of null-aware operation '?.' has type 'WidgetsBinding' which excludes null.

• 'WidgetsBinding' is from 'package:flutter/src/widgets/binding.dart' ('/C:/src/flutter/packages/flutter/lib/src/widgets/binding.dart'). package:flutter/…/widgets/binding.dart:1 WidgetsBinding.instance?.removeObserver(this);

Before, when i was using an older version, this error did not appear. can you please guide ? thanks

You need to upgrade adaptive_theme package to 3.0.0 too.

adaptive_theme: ^3.0.0
