🔌 Usage

1. Create a CSV Google Sheet

Create a sheet with your translations (follow the format below; example sheet here):

2. Share the Sheet

There are two options:

• If your Google Sheet is public, keep the setup as-is.

• If your Google Sheet is private, follow these steps:

  1. Enable Google Drive API and Generate an API Key
     Follow this guide: How to Use Google Drive API and Get an API Key

  2. Set the apiKey parameter in the @SheetLocalization annotation.

---

3. Declare the Localization Delegate

Create a Dart file (lib/utils/multi-languages/locale_keys.dart) with the following content:

import 'dart:ui';
import 'package:sheet_loader_localization/sheet_loader_localization.dart';

part 'locale_keys.g.dart';

@SheetLocalization(
  docId: 'DOCID',
  version: 1,
  outDir: 'resources/langs',
  outName: 'langs.csv',
  preservedKeywords: [],
  // OPTIONAL: Only required if your sheet is private
  apiKey: 'YOUR_GOOGLE_API_KEY',
)
class _LocaleKeys {}

---

4. Generate the Localizations

Run the command below to generate the localization file:

flutter pub run build_runner build
# or
flutter pub run build_runner build --delete-conflicting-outputs

---

5. Configure Your App

Follow the setup guide from the easy_localization README.

---

⚡ Regeneration

To force regeneration of the CSV and localization files (due to caching), simply increment the version field in @SheetLocalization and rerun the build command.

❓ Why This Tool?

easy_localization supports code generation, but not directly from Google Sheets. This tool simplifies localization workflows by using Google Sheets (ideal for collaboration with non-devs) and supports Flutter null safety.
