Flutter：“无法使用静态访问来访问实例成员'正在播放'。”

Question

我尝试为Flutter项目创建文字转语音功能，无法在视图中调用“播放”功能。这是我的代码：

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

未来_speak（）异步{

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是您在initSpeechRecognizer中拥有init的实例

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。但是对flutterTts错别字
