aljohara556 commented 3 years ago

I have a problem, when I try to converter the app language, I faced a problem,

[ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: NoSuchMethodError: The method 'restart' was called on null. E/flutter ( 6490): Receiver: null E/flutter ( 6490): Tried calling: restart() E/flutter ( 6490): #0 Object.noSuchMethod (dart:core-patch/object_patch.dart:51:5) E/flutter ( 6490): #1 LocalizedApp.restart (package:localize_and_translate/src/main.class.dart:258:11) E/flutter ( 6490): #2 LocalizeAndTranslate.setNewLanguage (package:localize_and_translate/src/main.class.dart:197:20) E/flutter ( 6490): <asynchronous suspension> E/flutter ( 6490): #3 _settingsState._onBackPressed.<anonymous closure>.<anonymous closure>.<anonymous closure> (package:erp_accounting_app/drawer_pages/setting.dart:159:32) E/flutter ( 6490): #4 new Future.delayed.<anonymous closure> (dart:async/future.dart:326:39)

this is my code :

translator.setNewLanguage( context, newLanguage: translator.currentLanguage == 'ar' ? 'en' : 'ar', remember: true, restart: true, );

what is the problem ??

Please share your flutter doctor -v output and initialization code

aljohara556 commented 3 years ago

this is the responce of flutter doctor ..

and the is the initialization code

void main() async { WidgetsFlutterBinding.ensureInitialized(); await translator.init( localeDefault: LocalizationDefaultType.device, languagesList: <String>['ar', 'en'], assetsDirectory: 'assets/langs/', );

msayed-net commented 3 years ago

okay, thanks for the details I will check it

msayed-net commented 3 years ago

Please test version 3.0.3, I believe it's solved

This is my code .

initialize


  WidgetsFlutterBinding.ensureInitialized();

  await translator.init(
    localeDefault: LocalizationDefaultType.device,
    languagesList: <String>['da', 'en'],
    assetsDirectory: 'language/',
  );

and the toggle

translator.setNewLanguage(
  context,
  newLanguage:
      translator.currentLanguage == 'en' ? 'da' : 'en',
  restart: true,
);

@mjmon did you wrap your main class inside runApp() method with LocalizedApp() !

example

mjmon commented 3 years ago

LocalizedApp() in main.dart fixed the error and converting the widget that contains the toggle button to a StatefulWidget solves it.

you can close it now. Thank you for your help.

Glad to hear that, thanks for sharing..
