Default language not working about i18n_extension

[marcglasberg]

By reading https://api.flutter.dev/flutter/widgets/WidgetsApp/localeResolutionCallback.html and https://api.flutter.dev/flutter/widgets/WidgetsApp/supportedLocales.html I'd say it's defaulting to NL because that's the first locale in the supportedLocales list you provided.

When you provide your localeResolutionCallback you are overriding the supportedLocales list, and then it really uses the de_DE locale, which doesn't exist, so it will then default to English.

You probably can obtain the same result by removing localeResolutionCallback and then putting Locale('en', 'US') as the first item in the supportedLocales list.

My i18n_extension can't really change the way the proper locale is decided by the MaterialApp widget.

Read that somewhere before, but didn't seem to make a difference. I'll try agian
