df_localization 0.7.1

A package that simplifies adding localization to your Flutter app.

Changelog

0.7.1

• feat: Add source-text translation versioning to AutoTranslationController (versionBySourceText, default true). Translations are stored under <key>@@<hash(sourceText)>, so rewording a string in a new release adds a new entry instead of overwriting the one already-deployed builds read — a one-string change costs one entry, not a database snapshot. Fixing a bad translation (same source) still propagates to all builds. Lookups fall back to legacy plain-key entries whose stored from matches, so pre-versioning databases keep resolving; run migrateToVersionedKeys(locales) once to additively snapshot them. RemoteTranslationController gets the same flag (default false) for servers that key their maps with versionedTranslationKey(key, sourceText).
• feat: The versioning helpers (versionedTranslationKey, translationSourceHash, kTranslationVersionSeparator) live in df_config ≥ 0.8.1 (pure Dart) and are re-exported here — Dart backends producing translation maps server-side can depend on df_config alone to key them. The hash is deterministic across platforms including web, and is pinned by a golden test.
• chore: Remove the df_log dependency — the runtime library never imported it, and the gen-translations CLI now prints with self-contained ANSI colors. Its ^0.5.1 constraint previously conflicted with hosts pinning newer df_log versions.

0.7.0

• Tagged but never published (pub.dev validation failure); all changes shipped in 0.7.1.

0.6.0

• breaking: Remove ClaudeTranslatorBroker, GeminiTranslatorBroker, OpenAITranslatorBroker — replaced by the unified LlmTranslatorBroker with .claude() / .gemini() / .openai() factory constructors that drive any AiBroker from ai_broker.
• breaking: Rename the gen-translations-gemini CLI to gen-translations. Adds a --provider claude|gemini|openai flag and drops the google_generative_ai dependency in favour of ai_broker.
• breaking: Bump df_config to ^0.8.0. Code that previously assigned TranslationManager.config = ... must switch to await TranslationManager.setConfig(...).
• feat: Add RemoteTranslationController for apps where translations are fetched from a backend via a single Future<Map<String, String>> Function(Locale) callback. Includes built-in stale-load protection for rapid locale switches.
• feat: Add .trIcu({args, preferKey, locale}) extension — full ICU MessageFormat support (plural, select, gender, selectordinal) with CLDR rules per locale, backed by intl's MessageFormat.
• feat: Add getSystemLocale() / getSystemLocales() / bestLocale(supported, {preferred}) — cross-platform locale helpers (iOS, Android, macOS, Windows, Linux, Web). bestLocale is a drop-in for MaterialApp.localeListResolutionCallback.
• feat: Add isRtlLocale(locale) / getTextDirection(locale) helpers for right-to-left languages.
• feat: Add ActiveLocale — process-wide active locale read by .trIcu() for plural rules and updated automatically by every controller's setLocale.
• fix: AutoTranslationController no longer poisons the new-locale cache or DB path when the user switches locale mid-translation.
• fix: First auto-translation against an empty remote database no longer crashes with Cannot modify unmodifiable map.
• fix: TranslationController.setLocale now awaits the file read so .tr() calls fired immediately after are guaranteed to see the new translations.
• fix: TranslationController.createInstance accepts the fileType parameter documented in the README.
