Platform localization

Flutter localization with OTA updates on top of your existing flow.

ReRune Flutter SDK 1.0.0 adds approved OTA text to generated localization flows while widgets keep using familiar delegates, supported locales, and getters.

Common challenge

Generated delegates and ARB files cover the app runtime, but teams still need translation coordination, QA, release timing, and runtime update control.

Best fit

Flutter teams that want faster translation cycles, lower localization costs, clear ownership and review of app copy, and approved OTA text updates after the initial SDK integration without waiting for another developer release or App Store and Google Play review.

How ReRune helps

ReRune adds dashboard context, CLI/API sync, AI assistance, and OTA publish IDs around the Flutter localization workflow instead of replacing Flutter conventions.

Workflow

From app copy to release-ready localization.

ReRune connects translation management to the delivery path developers already use: dashboard work, AI assistance, CLI/API sync, and OTA updates where a supported SDK is installed.

1

Install the SDK

Connect the supported app runtime to a ReRune publish ID while keeping native or framework localization behavior in place.

2

Publish approved text

Approve translation changes in the workspace, then publish runtime updates without turning every text fix into a full store release.

3

Refresh visible copy

Let supported SDK hooks check for updates and refresh text when new approved localization payloads are available.

4

Keep fallbacks intact

When runtime updates are unavailable, the app keeps reading bundled resources so localization failures do not break the product.

Coverage

App-first does not mean mobile-only.

Start where localization creates release friction, then keep web, mobile, and cross-platform products in one shared workspace as your surface area grows.

Developer delivery

Sync through the CLI. Publish through OTA SDKs.

Use the ReRune CLI locally or in CI/CD to manage project translations, then deliver approved runtime updates through the SDK built for your app.

Companion CLI

Install the ReRune CLI

Use the ReRune CLI to sync, validate, and manage translations right from your terminal. Run syncs in CI/CD or locally whenever you need to push a new language.

Homebrew (macOS/Linux):

brew install BasalBit/tap/rerune
  • Downloadable builds for macOS, Linux, and Windows
  • Uses the API keys you generate in the dashboard
  • Fits scripted CI/CD workflows through CLI and API access
rerune

Connect the project

Create the project config and connect the repository to its ReRune workspace.

rerune --pull

Pull approved updates

Bring current dashboard translations into the app or its build workflow.

rerune --push

Push local changes

Send local translation updates back to ReRune for the team to manage and publish.

ReRune for Flutter

Add OTA localization updates on top of your generated Flutter localizations without changing how widgets read translated strings.

  • Layers server-published translations over AppLocalizations
  • Works across mobile, web, and desktop from one setup
  • Generate config with dart run rerune and keep your existing API
  • Check for updates on start or trigger refresh manually at runtime

setup

dependencies:
  rerune: ^1.0.0

flutter gen-l10n
dart run rerune

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await ReRune.setup(
    otaPublishId: 'your-ota-publish-id',
    localizations: reRuneAppLocalizationsConfig,
  );

  runApp(const MyApp());
}

MaterialApp(
  localizationsDelegates: ReRune.localizationsDelegates,
  supportedLocales: ReRune.supportedLocales,
);

Why it feels lightweight

ReRune plugs into the standard Flutter localization flow, so your UI can keep using the same generated getters while published texts update in the background.

Main runtime APIs

Use ReRune.checkForUpdates(), listen to ReRune.onFetchedTextsApplied, or wrap screens with ReRuneBuilder when you want update-aware UI.

Questions

Questions teams ask before choosing a localization platform.

Does ReRune work with Flutter localization delegates?

Yes. With rerune 1.0.0, apps initialize ReRune before runApp(...) and keep using generated delegates, supported locales, and getters while approved OTA values apply in the background.

Can Flutter teams use ReRune without OTA?

Yes. Flutter teams can still use ReRune for project management, translation keys, AI assistance, import/export, and CLI/API sync even when OTA delivery is not part of the release plan.

What happens if an OTA localization update is unavailable?

Supported SDK flows keep bundled resources as the fallback. Runtime updates add approved text delivery on top of the app's existing localization path instead of replacing the safe baseline.
