What methods of adding localization to Flutter do you know?

In Flutter, there are several ways to add localization (i18n/l10n):

1. Using the flutter_localizations package — the official package from Flutter that provides basic localizations for widgets and materials.

2. Using the intl package — for working with formatting dates, numbers, and messages.

3. ARB (Application Resource Bundle) files — JSON-like files that store string translations for different languages.

4. flutter_intl package — a plugin to automate the generation of localized resources from ARB files.

5. Manual creation of a localization class — you can create your own class with methods to retrieve translated strings.

Example of using ARB and flutter_intl:

• Create files intl_en.arb, intl_ru.arb with keys and translations.
• The plugin generates Dart code with a localization class.
• In your code, call AppLocalizations.of(context).yourKey to get the translation.

This makes it easy to add new languages and maintain translations centrally.
