feat(i18n): localize the 4.x plugin, theme, and tools UI - #195
The ARB files cover the original screens, but most of the 4.x additions never
went through AppLocalizations: the plugin store, the Orplug Builder Studio,
the theme editor, the skin controls in Settings, the deep-link dialogs, the
batch summary, the Hasheous card, and the Watch Folder tab are all hard-coded
English. As a result, switching to zh_TW or zh still leaves large parts of the
new UI in English.
Change
Add 196 new keys to app_en.arb and wire the affected widgets and screens
through AppLocalizations.
Provide complete Traditional Chinese (app_zh_TW.arb) and Simplified Chinese
(app_zh.arb) translations for every new key. Other locales fall back to the
English template, matching the current behaviour of the existing untranslated
keys.
Keep file-picker titles, snackbars, dialog labels, empty states, validation
headings, and the new tools surfaces in the same localization path.
Regenerate with Flutter 3.47.9. This generator emits zh and zh_TW in one
app_localizations_zh.dart, so the old generated
app_localizations_zh_TW.dart is removed.
Update the widget tests that pump the new screens to install the localization
delegate, and format batch_stats.dart so the GUI formatting gate is clean.
Validation
flutter analyze — no issues.
dart format --output=none --set-exit-if-changed . in gui — clean.
flutter test — all localization-related suites pass; the only failure is
skinning_v2_test.dart failing to delete a temp directory on Windows because
a file is still open. The same test fails identically on an unmodified
origin/main checkout, so it is unrelated to this change.
Added a temporary smoke test rendering the plugin screen under
Locale('zh', 'TW') and Locale('zh'), confirming the translated tabs and
drop zone appear; the temporary test was not committed.
Summary by CodeRabbit
Localization
Expanded localized interface text across plugin management and the marketplace, theme editing, settings, batch results, game identification, and ROM tools.
Updated visible labels, prompts, and dialogs to use localized text, including media-type selection and mobile navigation.
Added Traditional Chinese translations and language-aware naming for Simplified and Traditional Chinese.
Move hard-coded English strings from the plugin store, Orplug Builder
Studio, theme editor, theme settings, deep-link dialogs, batch summary,
Hasheous card, and Watch Folder into ARB and wire them through
AppLocalizations.
Add the new keys in English plus Traditional and Simplified Chinese, then
regenerate the localization code with Flutter 3.47. The generator now emits
zh and zh_TW in a single app_localizations_zh.dart, so the stale
app_localizations_zh_TW.dart is removed. Widget tests that pump the new
screens now install the localization delegate.
Also apply dart format to batch_stats.dart so the GUI formatting gate stays
clean.
No actionable comments were generated in the recent review.
Walkthrough
The GUI now uses localized text across navigation, plugin interfaces, theme editing, settings, batch results, Hasheous results, and ROM tools. Localization resources expand across supported locales. Native locale-name lookup accepts a Locale. Several core code and test lines receive formatting-only changes.

Layer / File(s)
Summary
Localization messages gui/lib/l10n/*
Localization resources and accessors add labels and parameterized messages for navigation, plugin features, themes, settings, batch results, Hasheous, and ROM tools. Traditional Chinese messages move into the Chinese localization class.
Navigation and plugin interfaces gui/lib/app.dart, gui/lib/screens/plugins_screen.dart, gui/lib/widgets/{deep_link_dialog,sidebar,storefront_view}.dart, gui/test/*
Navigation, media prompts, plugin screens, storefront content, and deep-link dialogs use localized text. Related widget tests configure localization delegates and supported locales.
Studio, theme, and settings interfaces gui/lib/widgets/orplug_builder_studio.dart, gui/lib/screens/{theme_editor_screen,settings_screen}.dart
The plugin builder, theme editor, and settings screen use localized labels, picker titles, and status messages. Their operations remain unchanged.
Tools and result messages gui/lib/screens/tools_screen.dart, gui/lib/widgets/{batch_complete_dialog,hasheous_result_card}.dart, gui/lib/models/batch_stats.dart, gui/test/hasheous_result_card_test.dart
The tools screen, batch-completion dialog, and Hasheous result widgets use localized text. Tool workflows and the batch percentage calculation remain unchanged.
Blank theme names remain stable across UI languages, so the previously identified persistence risk is resolved. No actionable merge-blocking issue remains after normal checks.
Security architecture risk: Low · up to a12f7
The inspected changes preserve plugin-install confirmation and watch-folder behavior. The main behavioral difference is that saving an unnamed theme can produce different stored identities in different languages. No introduced security issue was established, but coverage remains incomplete.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The demonstrated theme-identity effect is bounded to custom-theme files in the application's support directory, selected-theme preferences, and exported theme metadata. The inspected change does not add authority to those operations.
Trust Boundaries and Controls
observed — An externally supplied deep-link target is still resolved against catalogue entries before installation. Missing entries return without installation; matching entries require explicit confirmation, and dialog dismissal returns false. Localization changes the displayed copy, not these controls. The dialog's checksum assurance text is not independent verification of the download implementation.
Resilience and Maintainability Implications
observed — Theme saving retains the existing write-then-reload sequence followed by theme selection. Save exceptions remain swallowed by the service, and the asynchronous save action remains nonserialized; these failure and repetition characteristics predate this PR rather than constituting newly introduced concerns.

These four files were already unformatted on main, so the GUI changes could
not get a green Quality Gate. Apply dart format only; no behaviour changes.
Added a follow-up commit formatting four core files (bin/openrom.dart, lib/src/watch_folder.dart, and two tests). They were already unformatted on main, and the Quality Gate checks core formatting after the GUI steps.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
English fallback text in the Arabic locale.
The new entries use English strings. The PR states that other locales fall back to the English template. This behavior is intentional. Users with the ar locale see mixed-language UI.

Use stable fallback names for persisted themes.
If the name field is blank, saving in different languages can create separate theme files and entries. Export also writes the localized fallback into the skin manifest. Keep the persisted fallback names non-localized.

getNativeName only received languageCode, so both zh and zh_TW mapped to
"简体中文". Pass the full Locale and derive languageCode_countryCode before
selecting the native name, and add a unit test for the two Chinese entries.
Keep the default theme and skin names as stable English constants so exported
manifests do not change with the active UI language.
Updated the PR with two fixes: (1) the language picker now passes the full Locale, so zh_TW shows 繁體中文 instead of a second 简体中文, with a unit test for both Chinese entries; (2) the default theme/skin names stay as stable English constants, so exported manifests do not depend on the active UI language (CodeRabbit finding).
