We will get exception in AdaptiveTextSelectionToolbar widget when using custom app that doesn't have DefaultCupertinoLocalizations.delegate

[EchoEllet]

We're using the AdaptiveTextSelectionToolbar widget and it requires those four delegates in the localizationsDelegates

If you are using a custom app like FluentApp you need to override the localizationsDelegates

with the following:

localizationsDelegates: const [
        DefaultCupertinoLocalizations.delegate,
        DefaultMaterialLocalizations.delegate,
        DefaultWidgetsLocalizations.delegate,
      ],

For example in FluentApp. This should be fixed once Fluent UI Issue #964 is published.

You probably experienced the issue since you were on mac platform and mac uses Cupertino locales (ig). Hence the issue.

Does every platform need to use their own locale system?

Yes, and fluent app widgets don't include Cupertino localizations by default, so you have to do this manually

The same error applies to iOS.

Can you go to the discussion and see the latest vote there??
