   Linkdy uses <a href="https://pub.dev/packages/slang">slang</a> to manage the translations of the application. To add a new translation, create a new file on <code>lib/i18n</code>, with the structure <code>strings_[lang_code].i18n.json</code>. When adding a new string, make sure to add the translation on all <code>.i18n.json</code> files. Then, run <code>dart run slang</code> to generate the translations.
