fast_i18n changelog | Flutter package

5.12.6 #

fix: add missing fallback for flat map if configured

5.12.5 #

In parallel with a new federated package structure, we have rebranded this library to slang.

It is recommended to migrate to slang as new features are only implemented there.

fast_i18n will only receive bug fixes.

You can read the migration guide here.

docs: add slang notice

5.12.4 #

fix: Flutter 3.0.0 compatibility

5.12.3 #

fix: resolve some linting errors in generated file

5.12.2 #

fix: handle csv files with 1st level lists

Add plural support: Swedish (thanks to Johannes Löhnn)

fix: migrate ARB files with plurals/selects correctly

5.12.0 #

feat: add comments feature for json and csv files
feat: new command flutter pub run fast_i18n:migrate arb en.arb en.json to migrate ARB files

5.11.0 #

feat: new command flutter pub run fast_i18n stats to get number of words, characters, etc.
fix: create missing directories instead of throwing an error

5.10.0 #

feat: add option locale_handling: false to not generate t and LocaleSettings (suitable for dependency injection)

5.9.0 #

Dependency Injection (optional)

Plural resolvers are now part of the translation class.

Meaning, you can now build your own instance without relying on LocaleSettings or any other side effects.

This is entirely optional! You can still use the included LocaleSettings solution.

// riverpod example
final english = AppLocale.en.build(cardinalResolver: myEnResolver);
final german = AppLocale.de.build(cardinalResolver: myDeResolver);
final translationProvider = StateProvider<StringsEn>((ref) => german);

// access the current instance
final t = ref.watch(translationProvider);
String a = t.welcome.title;

5.8.0 #

feat: allow custom parameter names in plurals or contexts (count and context were hardcoded previously)
feat: add path comment to every generated class

5.7.0 #

feat: add option timestamp to disable timestamp generation
feat: add option output_format to split output file
perf: flat translation map now declared separately for each locale

5.6.0 #

feat: add CSV support
feat: improve generic type detection for lists (e.g. List<List<String>>,List<Map<String, String>>)
feat: make optional class members (from interfaces) non-nullable when possible

5.5.0 #

Namespaces

Split your translations into different files. Each file represents a namespace:

i18n/
  widgets/
    - widgets.i18n.json
    - widgets_fr.i18n.json
  dialogs/
    - dialogs.i18n.json
    - dialogs_fr.i18n.json

Interfaces

Create common super classes for different nodes. This allows for more type safety. Instead of List<dynamic>, we can have List<PageData>

{
  "pages": [
    {
      "title": "E2E encryption",
      "content": "Your data is safe!"
    },
    {
      "title": "Sync",
      "content": "Synchronize all your devices!"
    }
  ]
}

With the generated mixin:

mixin PageData {
  String get title;
  String get content;
}

See updated README for further information about those features.

feat: different casing for map keys via key_map_case

New recommended setup (see README):

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  // LocaleSettings.useDeviceLocale();
  runApp(TranslationProvider(child: MyApp())); // Wrap your app with TranslationProvider
}

MaterialApp(
  locale: TranslationProvider.of(context).flutterLocale, // use provider
  supportedLocales: LocaleSettings.supportedLocales,
  localizationsDelegates: GlobalMaterialLocalizations.delegates,
)

5.1.0 #

feat: add param_case configuration to recase parameters

5.0.4 #

5.0.2 #

fix: transform keys with multiple digits according to key_case correctly

5.0.1 #

fix: Missing PluralResolver when pluralization is not used in project

This release mostly focuses on simplifications of build.yaml.

Breaking: builder name renamed from fast_i18n:i18nBuilder to fast_i18n
Breaking: plural auto detection is on by default (auto: cardinal)
Breaking: fallback strategy option strict is now none
Breaking: key paths in build.yaml must be cased according to key_case if specified
Breaking: your project must be null safe

You can read the detailed migration guide here.

4.11.0 #
