This workaround fixes this issue.

Basically, it adds an exception for Dart linter so that there is no warnings.

This trick is heavily used in build_value_generator.

after upgrading to Flutter 2.0 and update some package to be compatible with Flutter 2.0, i got this issue:

Because flutter_launcher_icons >=0.9.0 depends on args 2.0.0 and gen_lang 0.1.3 depends on args >=0.12.1 <2.0.0, flutter_launcher_icons >=0.9.0 is incompatible with gen_lang 0.1.3.

And because no versions of gen_lang match >0.1.3 <0.2.0, flutter_launcher_icons >=0.9.0 is incompatible with gen_lang ^0.1.3.

can you upgrade the args package?

Hello,

First thank you for the good library!

I'm facing an issue when trying to set a BottomNavigationBarItem Title.

BottomNavigationBarItem(
                icon: Icon(Icons.dialpad),
                title: new Text( S.of(context).example )
              )

It throws the following errors:

Invalid constant value.

The values in a const list literal must be constants. Try removing the keyword 'const' from the list literal.

Arguments of a constant creation must be constant expressions. Try making the argument a valid constant, or use 'new' to call the constructor

Using a simple string, such as Text('Test') it works.

Do you think it's possible to solve this issue?

Thank you!

generated files not working anymore.

is there a way to bring the gen_lang package to the current versions?

Declaring a string that contains ' (for example l'aggiornamento) the resulting generation will contains double quotes.

Futhermore if you insert a \n the resulting string will be broken because in the generated file the \n breaks the line (it's not kept inside the text) and the string it's splitted into 2 strings and this results in a broken file that cannot be compiled

Possible solution: use double quote when initialize the string object in the generated file

Location changes correctly but in application bar text always in en location

`class RegisterPage extends StatelessWidget { final UserRepository userRepository;

RegisterPage({Key key, @required this.userRepository}) : assert(userRepository != null), super(key: key);

@override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(S.of(context).app_bar_register), ), body: BlocProvider( create: (context) { return RegisterBloc( authenticationBloc: BlocProvider.of(context), userRepository: userRepository, ); }, child: RegisterForm(), ), ); } }`

Hello,

I am using last version of this package alongside with dart 2.6.1 :

dart --version output:

Dart VM version: 2.6.1 (Mon Nov 11 13:12:24 2019 +0100) on "macos_x64"

On VSCode, dart linter shows these infos on gen_lang generated files :

It concerns mostly messages with parameters :

String yearsAgo(val) {
    return Intl.message("${val} years ago", name: 'yearsAgo', args: [val]);
}

This is the link to Dart language specs about string interpolation.

Thanks

I have encountered this issue when I try using one of the following packages

firebase_crashlytics: ^2.4.4
firebase_messaging: ^11.2.4
firebase_core: ^1.10.66
flutter_local_notifications: ^9.1.5

with gen_lang: ^0.1.3 Issue seems to be related with args, cause of this log when I run flutter pub get :

Because no versions of gen_lang match >0.1.3 <0.2.0 and gen_lang 0.1.3 depends on args >=0.12.1 <2.0.0, gen_lang ^0.1.3 requires args >=0.12.1 <2.0.0. And because dbus >=0.2.0 depends on args ^2.0.0, gen_lang ^0.1.3 is incompatible with dbus >=0.2.0. And because flutter_local_notifications >=9.1.5 <10.0.0-dev.1 depends on flutter_local_notifications_linux ^0.4.0 which depends on dbus ^0.6.0, gen_lang ^0.1.3 is incompatible with flutter_local_notifications >=9.1.5 <10.0.0-dev.1.

Is there any planned update for this? Or am I missing anything!?

Hi!

It would be nice to be able to put nested objects in the JSON file to sort properties by more intuitive groups rather than separating them by a prefix.

Hello,

Getting the following error when trying to run flutter pub run gen_lang:generate

Hello.

There is some issue with random sort order of locales in generated files (i18n.dart and messages_all.dart). Maybe platform related. For example: i18n.dart on Max OS: return const [ Locale("en", ""), Locale("uk", ""), Locale("pl", ""), Locale("ru", ""),
]; On Ubuntu: return const [ Locale("en", ""), Locale("ru", ""), Locale("pl", ""), Locale("uk", ""), ];

messages_all.dart - even worse. We want this files to be included in git, instead of regenerate them each time we run build. So it would be great if sort could be fixed.
