remove_unused_localizations

A Flutter development tool that automatically detects and removes unused localization keys from .arb files, keeping your project clean and optimized.

Features

✅ Scans all .arb files dynamically (supports multiple languages).
✅ Detects and removes only truly unused keys (avoiding false deletions).
✅ Works with global localization variables like:

localizations.welcome
S.of(context).welcome
AppLocalizations.of(context)!.welcome

✅ Excludes important files (e.g., app_localizations.dart).
✅ Provides a detailed report of removed keys.

Installation

Add the package to your dev dependencies in pubspec.yaml:

dev_dependencies:
  remove_unused_localizations: ^1.0.0

Run:

flutter pub get

Usage

Run the Package from the Terminal

You can run the package directly as a CLI tool using:

dart run remove_unused_localizations

This will automatically scan all .arb files in your project, detect unused keys, and remove them, keeping your localization files clean and optimized.

If you want to keep the unused keys in order to delete it manually you can use this command:

dart run remove_unused_localizations --keep-unused

Example Output

Unused keys found: welcome_message, login_button
Updated lib/l10n/app_en.arb, removed unused keys.
Updated lib/l10n/app_ar.arb, removed unused keys.
✅ Unused keys successfully removed.
