the file are constantly reloading thus creating NPE isue

The following NoSuchMethodError was thrown building Consumer<OrganizationInfoModel>(dirty, dependencies: [_InheritedProviderScope<OrganizationInfoModel>, _LocalizationsScope-[GlobalKey#78eaf]]):
The method '[]' was called on null.
Receiver: null
Tried calling: []("")

The relevant error-causing widget was
ViewModelBuilder<OrganizationInfoModel>
lib/…/auth/organization_info_screen.dart:20
When the exception was thrown, this was the stack

configuration is done in main.dart

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    precacheImage(AssetImage('assets/images/dark_logo_transparent-no-write.png'), context);
    final flutterI18nDelegate = FlutterI18nDelegate(

        useCountryCode: false,

        basePath: 'assets/i18n',
        forcedLocale: Locale('en'),
        decodeStrategies: [YamlDecodeStrategy()],
      ),
      missingTranslationHandler: (key, locale) {
        print('--- Missing Key: $key, languageCode: ${locale.languageCode}');
      },
    );

....

return MaterialApp(
      builder: ExtendedNavigator.builder<route.Router>(
        router: route.Router(),
        guards: [AuthGuard()],
      ),
      debugShowCheckedModeBanner: false,
     
      localizationsDelegates: [flutterI18nDelegate, GlobalMaterialLocalizations.delegate, GlobalWidgetsLocalizations.delegate],

when reload ends the screen is reloaded and red screen disappear

Hi Enrico,
can you reproduce the issue with the example project?
if not, can you provide me an example project in which this happens?

Miamoto-Musashi commented

Hi, I'm using the old version and cannot upgrade flutter to the new version.

here the YAML file I use maybe is related to num of rows

cheers

ilteoood commented

I tried to integrate your yml in the example app: it loads without problem.

Can you try to include WidgetsFlutterBinding.ensureInitialized(); under the delegate declaration?

Here is an example from the example app

Future main() async {
  final FlutterI18nDelegate flutterI18nDelegate = FlutterI18nDelegate(
    translationLoader: FileTranslationLoader(
        useCountryCode: false,
        fallbackFile: 'en',
        basePath: 'assets/i18n',
        forcedLocale: Locale('es')),
  );
  WidgetsFlutterBinding.ensureInitialized();
  runApp(MyApp(flutterI18nDelegate));
}
Miamoto-Musashi commented

Hi,
I have the ensure Initialized on the main class

void main() async {
  initializeReflectable();
  putLumberdashToWork(withClients: [ColorizeLumberdash(), SentryLumberdash.withDsn(dsnKey: Values.sentryDnsKey)]);

  // await setupSnackbarUi();
  WidgetsFlutterBinding.ensureInitialized();

  await setupHive();
  await setupLocator();
  await setupDialogUi();

  runApp(GetMaterialApp(home: MyApp()));
}

do you think it does change?

the problem BTW is not on first loading, the app loads well, the problem is that during a rebuild of the widget tree the .yml file is reloaded (I'm using filledstack MVVM architecture) and the rendering is done with a Null value; after the .yml reload is complete the screen reload again but now the value is correct and the rendering is successful

ilteoood commented

Can you tell me the version of the library that you're using?

Miamoto-Musashi commented

Hi, the version is flutter_i18n: ^0.21.1

ilteoood commented

On example app this issue can't be reproduced.

If you encounter this again, please reproduce it with the example app provided with this repository, or create a new one that can prove the bug.
