Filament default language issue

Level 58

To change the default language in a Laravel application using Filament, you need to ensure a few things are correctly set up. Here are the steps to troubleshoot and resolve the issue:

Set the Locale in config/app.php: Make sure you have set the locale to ru in your config/app.php file.
```
'locale' => 'ru',
```
Check Language Files: Ensure that you have the necessary language files for Russian in the resources/lang/ru directory. If these files are missing, you need to create them or download them from a reliable source.
Clear Cache: After making changes to the configuration, clear the cache to ensure the changes take effect. Run the following commands:
```
php artisan config:cache
php artisan cache:clear
php artisan view:clear
```
Set Locale in Filament Configuration: Filament may have its own configuration for localization. Check the config/filament.php file and ensure the locale is set correctly.
```
'locale' => 'ru',
```
Middleware for Localization: Ensure that the \Illuminate\Session\Middleware\StartSession and \Illuminate\View\Middleware\ShareErrorsFromSession middleware are included in your web middleware group in app/Http/Kernel.php.
Verify Filament Translations: Filament should have its own translation files. Ensure that the translations for Filament are available in the resources/lang/vendor/filament/ru directory.

Here is a summary of the steps in code:

Update config/app.php:
```
'locale' => 'ru',
```

Clear Cache:

php artisan config:cache
php artisan cache:clear
php artisan view:clear

Update config/filament.php:
```
'locale' => 'ru',
```

By following these steps, you should be able to change the default language of your Laravel application using Filament to Russian. If the issue persists, double-check that all necessary translation files are in place and correctly named.
