12-23: Consider improving test setup clarity and error handlingA few suggestions to enhance the test setup:
- Consider adding a comment explaining the purpose of the 'fb' locale (fallback?)
- The error handler could include assertions or test failures for better error visibility
- The hardcoded 'path' value could be made more meaningful or documented
var r = EasyLocalizationController( - forceLocale: const Locale('fb'), + // 'fb' represents a fallback locale for testing + forceLocale: const Locale('fb'), supportedLocales: [const Locale('en'), const Locale('ar'), const Locale('ru'), const Locale('fb')], fallbackLocale: const Locale('fb'), - path: 'path', + path: 'test/fixtures', // Path to test translation files useOnlyLangCode: true, useFallbackTranslations: true, onLoadError: (FlutterError e) { - log(e.toString()); + log(e.toString()); + fail('Failed to load translations: ${e.toString()}'); }, saveLocale: false, assetLoader: const JsonAssetLoader());
29-74: Consider adding edge cases to English pluralization testsThe English pluralization tests are comprehensive for positive integers, but consider adding:
- Tests for negative numbers
- Tests for decimal numbers
- Documentation explaining the behavioral differences between
ignorePluralRules=true/falsegroup('English plural', () { + // Tests behavior with decimal numbers + test('English decimal numbers (no ignorePluralRules)', () async { + Localization.load( + const Locale('en'), + translations: r.translations, + fallbackTranslations: r.fallbackTranslations, + ignorePluralRules: false, + ); + expect(Localization.instance.plural('hat', 1.5), 'other hats'); + expect(Localization.instance.plural('hat', 0.5), 'other hats'); + }); + + // Tests behavior with negative numbers + test('English negative numbers (no ignorePluralRules)', () async { + Localization.load( + const Locale('en'), + translations: r.translations, + fallbackTranslations: r.fallbackTranslations, + ignorePluralRules: false, + ); + expect(Localization.instance.plural('hat', -1), 'other hats'); + expect(Localization.instance.plural('hat', -2), 'other hats'); + });
76-127: Add documentation explaining Russian plural rulesThe Russian pluralization tests are comprehensive but would benefit from documentation explaining the language-specific rules. Consider adding comments explaining:
- The rules for 'few' (2-4, 22-24, etc.)
- The rules for 'many' (5-20, 25-30, etc.)
- Special cases like numbers ending in 1 but not 11
group('Russian plural', () { + // Russian has complex plural rules: + // one: n mod 10 = 1 and n mod 100 != 11 + // few: n mod 10 = 2..4 and n mod 100 != 12..14 + // many: n mod 10 = 0 or n mod 10 = 5..9 or n mod 100 = 11..14 + // other: everything else + test('Russian one', () async {
129-192: Add documentation for Arabic plural rules and verify issue #729 fixThe Arabic pluralization tests address the issue mentioned in #729, but would benefit from:
- Documentation explaining Arabic plural rules
- Comments linking these tests to issue Plural Support Missing 'Few' Case for Some Languages Like Arabic | Default Behavior of ignorePluralRules #729
- Additional test cases for boundary conditions
group("Arabic plural", () { + // Arabic plural rules: + // zero: n = 0 + // one: n = 1 + // two: n = 2 + // few: n mod 100 = 3..10 + // many: n mod 100 = 11..99 + // other: everything else + // + // Related to issue #729: Missing 'few' case for numbers <= 10 + test('Arabic few (no ignorePluralRules)', () async {
1-212: Consider structuring tests for better maintainabilityWhile the tests are comprehensive, consider these architectural improvements:
- Extract test data into fixture files to separate test logic from test data
- Create shared setup functions for common locale configurations
- Add a test matrix to ensure consistent coverage across all locales
Would you like assistance in implementing any of these improvements?

320-324: Enhance the introduction with specific language examples.The introduction effectively explains the default behavior but could be more helpful by explicitly mentioning which languages require the
fewandmanycategories.Consider expanding the introduction like this:
-In some languages, pluralization is simple and only involves using zero, one, two, and other forms, without needing to handle the `few` or `many` categories. +In some languages like English, pluralization is simple and only involves using zero, one, two, and other forms. However, other languages like Arabic, Russian, and Polish require additional plural categories such as `few` or `many` for grammatically correct translations.
329-337: Add a practical example demonstrating plural forms.While the configuration example is clear, it would be more helpful to include a practical example showing the actual plural forms in use.
Consider adding this example after the configuration:
EasyLocalization( ignorePluralRules: false, // Set this line to false to enable 'few' and 'many' plural categories supportedLocales: [Locale('en', 'US'), Locale('de', 'DE')], path: 'assets/translations', fallbackLocale: Locale('en', 'US'), child: MyApp() ) +// Example for Arabic pluralization with all forms: +{ + "items": { + "zero": "لا يوجد عناصر", + "one": "عنصر واحد", + "two": "عنصران", + "few": "{} عناصر", // For numbers 3-10 + "many": "{} عنصراً", // For numbers 11-99 + "other": "{} عنصر" // For everything else + } +}

338-341: LGTM! Clear explanation of the configuration impact.
The final explanation clearly states the effect of setting ignorePluralRules: false.
320-341: Documentation changes successfully address issue #729.
The new section effectively documents the solution to the missing 'few' plural case issue in Arabic and similar languages. The content is well-structured and provides clear guidance for users needing to handle additional plural categories.
✅ Verification successful
Documentation accurately reflects implementation and test coverage
The documentation changes are well-aligned with the codebase implementation, as evidenced by comprehensive test coverage across multiple test files. The tests verify:
- Proper handling of 'few' and 'many' plural cases when
ignorePluralRules: false - Language-specific plural rules (including Russian and Arabic)
- Widget integration with plural rules
- Various numeric cases for different plural forms

Fix incorrect locale in Arabic test case
There appears to be a bug in the test setup. The test is titled "Arabic all cases" but uses the English locale ('en') instead of Arabic ('ar').
Localization.load(
- const Locale('en'),
+ const Locale('ar'),
translations: r.translations,
fallbackTranslations: r.fallbackTranslations,
ignorePluralRules: true,📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
