Flutter ：“无法使用静态访问访问实例成员“正在播放”。”

Question

我尝试为我的 Flutter 项目创建文本转语音，我无法在视图中调用“播放”功能。

这是我的代码：

void initSpeechRecognizer(){
    FlutterTts flutterTts = FlutterTts();

    Future _speak() async{

      var result = await flutterTts.speak("Hello World");

      if (result == 1) setState(() => flutterTts = _VoiceHomeState.playing);

      List<dynamic> languages = await flutterTts.getLanguages;

      await flutterTts.setLanguage("id-ID");

      await flutterTts.setSpeechRate(1.0);

      await flutterTts.setVolume(1.0);

      await flutterTts.setPitch(1.0);

      await flutterTts.isLanguageAvailable("id-ID");

    }

  }

}

Answer 1

此行导致错误

 if (result == 1) setState(() => flutterTts = _VoiceHomeState.playing);

flutterTts 是你在 initSpeechRecognizer 中的一个实例

在 Fultter_TTS 的示例代码中

TtsState ttsState = TtsState.stopped;
...
var result = await flutterTts.speak(_newVoiceText);
    if (result == 1) setState(() => ttsState = TtsState.playing);
  }

我认为您正在尝试设置 TtsState。 但是 flutterTts 的拼写错误
