La instrucción técnica y profesional habrá de ser generalizada; el acceso a los estudios superiores será igual para todos, en función de los méritos respectivos.';
  TranslationModel _translated = TranslationModel(translatedText: '', detectedSourceLanguage: '');
  TranslationModel _detected = TranslationModel(translatedText: '', detectedSourceLanguage: '');

  @override
  void initState() {
    _translation = Translation(
      apiKey: 'YOUR_API_KEY',
    );
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
