你能试试这个吗;

void initSpeechRecognizer(){
    _speechRecognition = SpeechRecognition
FloatingActionButton(
                    child: Icon(Icons.mic),
                    onPressed: () async {
                      if(_isAvailable && !_isListening){
                          var result = await _speechRecognition.listen(locale: "id_ID");
                          print('result : $result');
                      }
                    },
                     heroTag: "mic",
                  ),
