When validatorof TextFormField widget returns an AppLozalizations.of(context).translationKey value, error message does not refresh with locale change #143729
Description
Steps to reproduce
- Create a Form in your Flutter App using a
TextFormField(). - Localize your Flutter app according to the docs.
- Build simple form validation according to the docs, by returning a localized string via the
validator(e.g.AppLocalizations.of(context).myTranslation). - Test the app using
flutter run, and provide invalid input and trigger validation. - This will show an according error message displayed in the current app locale.
- Trigger a locale language switch in your app (we're currently doing this using a provider to whose value the
localeproperty of theMaterialApp/CupertinoApplistens to).
Expected results
The locale should be switched in the entire app, to the language to which the locale switch occurred.
Actual results
Every string present in the app via AppLocalizations.of(context)... changes, except for the strings returned via the validator property in the TextFormField() widget & displayed in the way mentioned above before the language switch. Only a new call to formKey.currentState.validate() will refresh the validation error messages according to the newly selected language.
This issue has also been mentioned on so, still without a really viable solution.
