@juanagu you need to set your fromLanguage, since you're translating from English, set that to SupportedLanguages.English

Thanks! @rishab2113 I had an error on my code. I Replaced: String fromLanguage = languages.first.toString();

To

String fromLanguage = languages.first.languageCode.toString();
