Error when building iOS app

[Jan Brinkmann]

Getting the following error after upgrading to 4.0.0:

../../../Flutter/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_translate-4.0.0/lib/src/utils/device_locale.dart:11:49: Error: Property 'window' cannot be accessed on 'WidgetsBinding?' because it is potentially null.
     - 'WidgetsBinding' is from 'package:flutter/src/widgets/binding.dart' ('../../../Flutter/flutter/packages/flutter/lib/src/widgets/binding.dart').
    Try accessing using ?. instead.
      final deviceLocales = WidgetsBinding.instance.window.locales;

Yes it seems this issue occurs in stable channel.

Seems like 4.0.1 doesn't contain the changes i made

[Florin Bratan]

Fixed now in 4.0.2

[Jan Brinkmann]

Confirm, thanks for the quick response!
