@xster

This is probably due to #22443, where we have started adding cupertino localizations. The problem should go away if you provide the defaultCupertinoLocalizations to the material app, though perhaps we need to include them by default>

cc @xster

This is terrible. Hope the patch land soon.

@alardizabal

@alardizabal Thanks for observe this bug, it's emergency for now, I can reproduce this both on Cupertino APP and Material APP on iOS. Waiting for Flutter team fix this, otherwise copy and paste the basic usage are limited and buggy.

The patch is on head

@xster

@xster @zoechi

If I use themeData platform is TargetPlatform.ios in MaterialApp on android device, then the pasteButtonLabel warning is showing like the issue. Not warning on iOS device. but i18n not valid.

like the code https://github.com/CaiJingLong/localization_error_example/blob/master/lib/main.dart
github repo

If I delete

GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,

then i18n not valid, and language is english, not chinese.

Everything was normal before the update in v0.9.1, and there was a problem after the 0.10.

before upgrade flutter version 0.9.1 ,anything is true

@DJafari

@DJafari I don't understand what you're asking. Can you please file a new bug describing the issue you're seeing?
https://github.com/flutter/flutter/issues/new

@eseidelGoogle

@eseidelGoogle bug described in this issue, please read this issue

example :

import 'package:flutter/material.dart';
import 'package:flutter_localizations/flutter_localizations.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      localizationsDelegates: [
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
      ],
      supportedLocales: [
        Locale("fa", "IR")
      ],
      locale: Locale("fa", "IR"),
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatelessWidget {
  MyHomePage({Key key, this.title}) : super(key: key);
  final String title;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(title),
      ),
      body: Container(
        child: Padding(
          padding: EdgeInsets.all(8),
          child: TextFormField(

          ),
        ),
      ),
    );
  }
}

note:
run in iOS and hold on textfield to show Copy/Paste menu

@DJafari

@DJafari regardless, this issue is has been closed for 6 months. :) Even if this issue contains some of the right information, a new issue is likely still going to be needed to cause it to be resolved. Please file a new issue if you would like this resolved. Thank you!

@xster is likely the person who would resolve issues in this code.

@eseidelGoogle

@eseidelGoogle ok thanks :-) #30722

This issue was regarding a crash that was happening on 0.9.6 with the default English implementation.

#13452 is the issue tracking the flutter_localizations package providing bundled language translations for 52 other languages such as Farsi. The work is done but not all the PRs are merged into head yet.

@xster

ok @xster thanks
can you give a ETA ? because of this bug caused app can't production ready

@OverRide

I've found a solution to the problem, had to add fallback to localizationsDelegates, as follows:

localizationsDelegates: [ ..... const FallbackCupertinoLocalisationsDelegate(), ]

And the delegate:

`class FallbackCupertinoLocalisationsDelegate
extends LocalizationsDelegate {
const FallbackCupertinoLocalisationsDelegate();

@OverRide
bool isSupported(Locale locale) => true;

@OverRide
Future load(Locale locale) =>
DefaultCupertinoLocalizations.load(locale);

@OverRide
bool shouldReload(FallbackCupertinoLocalisationsDelegate old) => false;
}`

@MohamedSayed9392

@MohamedSayed9392 tried but didn't work, could you be more specific ? In the class Fallback(...) you import LocalizationsDelegate from material or cupertino ? And when you use it in
localizationsDelegates: [ ..... const FallbackCupertinoLocalisationsDelegate(), ], what else is written before or after const FallbackCupertinoLocalisationsDelegate() ?
My initial code :
localizationsDelegates: [ const LocalizationDelegate(), GlobalMaterialLocalizations.delegate, GlobalWidgetsLocalizations.delegate ],
I tried replacing the const by yours it didn't work.

@Mayaela

@Mayaela

This solution worked for me:

class FallbackCupertinoLocalisationsDelegate
    extends LocalizationsDelegate<CupertinoLocalizations> {
  const FallbackCupertinoLocalisationsDelegate();

  @override
  bool isSupported(Locale locale) => true;

  @override
  Future<CupertinoLocalizations> load(Locale locale) =>
      DefaultCupertinoLocalizations.load(locale);

  @override
  bool shouldReload(FallbackCupertinoLocalisationsDelegate old) => false;
}

Notice the that here CupertinoLocalizations was provided as type for generics.

Not sure about what exactly it does, but I fix this bug using platform at Android for my ThemeData above my form :

                          child: Theme(
                            data: new ThemeData(
                              platform: TargetPlatform.android,
                              hintColor: Style.circleGrey,
                              primaryColor: Style.redDarkAccent,
                              primaryColorDark: Style.redDarkAccent,
                            ),

the navigation back in the drag is interrupted in iOS, when we force the platform: TargetPlatform.android

@OverRide

I've found a solution to the problem, had to add fallback to localizationsDelegates, as follows:

localizationsDelegates: [ ..... const FallbackCupertinoLocalisationsDelegate(), ]

And the delegate:

`class FallbackCupertinoLocalisationsDelegate
extends LocalizationsDelegate {
const FallbackCupertinoLocalisationsDelegate();

@OverRide
bool isSupported(Locale locale) => true;

@OverRide
Future load(Locale locale) =>
DefaultCupertinoLocalizations.load(locale);

@OverRide
bool shouldReload(FallbackCupertinoLocalisationsDelegate old) => false;
}`

Thank you, this worked for me as well.
Created a new .dart file with:

import 'package:flutter/cupertino.dart';

class FallbackCupertinoLocalisationsDelegate
    extends LocalizationsDelegate<CupertinoLocalizations> {
  const FallbackCupertinoLocalisationsDelegate();

  @override
  bool isSupported(Locale locale) => true;

  @override
  Future<CupertinoLocalizations> load(Locale locale) =>
      DefaultCupertinoLocalizations.load(locale);

  @override
  bool shouldReload(FallbackCupertinoLocalisationsDelegate old) => false;
}

then added that class as the last in the main file:

MaterialApp(
...
localizationsDelegates: [
          ...
          GlobalMaterialLocalizations.delegate,
          GlobalWidgetsLocalizations.delegate,
          const FallbackCupertinoLocalisationsDelegate(),
        ],

and worked perfectly

Hi from Flutter 1.10.12:

now you can use:

localizationsDelegates: [
              ...
              GlobalMaterialLocalizations.delegate,
              GlobalWidgetsLocalizations.delegate,
              GlobalCupertinoLocalizations.delegate,
              DefaultCupertinoLocalizations.delegate
],

GlobalCupertinoLocalizations.delegate,

Yes, adding this line does the trick.
