setState(() => _currentLocale = locale));
_speech.setRecognitionStartedHandler(()
=> setState(() => _isListening = true));
// this handler will be called during recognition.
// the iOS API sends intermediate results,
// On my Android device, only the final transcription is received
_speech.setRecognitionResultHandler((String text)
=> setState(() => transcription = text));
_speech.setRecognitionCompleteHandler(()
=> setState(() => _isListening = false));
// 1st launch : speech recognition permission / initialization
_speech
.activate()
.then((res) => setState(() => _speechRecognitionAvailable = res));
//..
speech.listen(locale:_currentLocale).then((result)=> print('result : $result'));
