translator

Free Google Translate API for Dart

See it in pub: https://pub.dev/packages/translator
and GitHub: https://github.com/gabrielpacheco23/google-translator

Usage

void main() async {
  final translator = GoogleTranslator();

  final input = "Здравствуйте. Ты в порядке?";

  translator.translate(input, from: 'ru', to: 'en').then(print);
  // prints Hello. Are you okay?
  
  var translation = await translator.translate("Dart is very cool!", to: 'pl');
  print(translation);
  // prints Dart jest bardzo fajny!

  print(await "example".translate(to: 'pt'));
  // prints exemplo
}

 

Using translate method passing the args from and to designates the language from text you're typing and the language to be translated

translator.translate("I love Brazil!", from: 'en', to: 'pt').then((s) {
    print(s);
  }); 
  // prints Eu amo o Brasil!

 

or you can omit from language and it'll auto-detect the language of source text

translator.translate("Hello", to: 'es').then(print);
// prints Hola

 

and also pass the value to a var using await

var translation = await translator.translate("I would buy a car, if I had money.", from: 'en', to: 'it');
print(translation);
// prints Vorrei comprare una macchina, se avessi i soldi.

 

The returned value is a Translation object which holds the translation stuff

var translation = await translator.translate('Translation', from: 'en', to: 'es');
print('${translation.source} (${translation.sourceLanguage}) == ${translation.text} (${translation.targetLanguage})');

// prints Translation (English) == Traducción (Spanish)

 

You can use the extension method directly on the string too

print(await "example".translate(to: 'pt'));
// prints exemplo

 

There is translateAndPrint method that prints directly

translator.translateAndPrint("This means 'testing' in chinese", to: 'zh-cn');
// prints 这意味着用中文'测试'

 

TranslatedText Widget

You can use the TranslatedText widget as a replacement for the Text widget to get the benefits of translate() method directly in the widget tree (UI Layer).

TranslatedText(
  "Hello, World!",
  loadingText: 'Loading...',
  from: 'en',
  to: 'ar',
  style: TextStyle(fontSize: 20),
)

// prints مرحبا بالعالم!
