Localize Firstlight Chrome

Firstlight-owned chrome (Confirm, Cancel, OK, dismiss, clear, skip, Done, crop, zoom, crop move, media source chooser, and password reveal) comes from one Laravel language file. Authored labels on Confirmation Dialog and Alert Dialog still win. Date Picker and Time Picker keep rejecting Blade confirm-label and cancel-label; their sheet buttons are package chrome only.

The package ships English, German (de), Spanish (es), French (fr), Italian (it), Japanese (ja), Dutch (nl), Polish (pl), Brazilian Portuguese (pt_BR) and Simplified Chinese (zh_CN). Laravel picks the strings for the application locale, so no setup is needed for those. There is no translation UI. To change a packaged string or add another locale, publish the language files.

Publish the language files

php artisan vendor:publish --tag=firstlight-lang

Laravel copies every packaged locale to lang/vendor/firstlight. Edit a published file to change a packaged string; your copy wins over the package. validation.php holds the pluralised error summary heading ('summary' => 'There is :count error.|There are :count errors.') used by error-summary Callouts and screen-reader announcements. Keep its :count placeholder and one plural form per rule of the language, as Polish does with three.

To add a locale Firstlight does not ship, create its directory next to the others, for example lang/vendor/firstlight/sv/chrome.php, and keep the same keys:

<?php

return [
    'confirm' => 'Bekräfta',
    'cancel' => 'Avbryt',
    'ok' => 'OK',
    'dismiss' => 'Stäng',
    'clear_search' => 'Rensa sökning',
    'show_password' => 'Visa lösenord',
    'hide_password' => 'Dölj lösenord',
    // ...the remaining keys from lang/vendor/firstlight/en/chrome.php
];

Missing keys fall back to the packaged English strings.

Date and Time picker locale and timezone

When locale or timezone is omitted, Date Picker and Time Picker inherit the application:

locale from the translator (en_AU and en_AU.UTF-8 become en-AU)
timezone from config('app.timezone') when it is a real IANA identifier

Explicit picker props still win. Invalid inherited values are omitted so the device calendar and clock are used; they do not throw. Authored malformed locale or timezone attributes still fail before publication.

Authored field labels, helpers, errors, dialog titles, and Feedback messages are ordinary Blade strings; translate those with __() as you already would.
