FloatingActionButton onpressed（）在flutter中不起作用

Question

當我點擊工廠時，這里發生的事情是我的代碼也許你們其中一個人可以幫忙:)

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

你能嘗試一下嗎？

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",
                  ),
