我是react native的新手，正在尝试在我的应用程序中开发语音转录功能。我希望在人们使用麦克风时得到一个字符串。我在网上找到了几个解决方案，但对于native应用程序，我使用的是EXPO。我使用的是“react-native-google-cloud-speech-to-text”，但我一直收到以下错误：类型错误：null不是对象（计算“GoogleCloudSpeechToText. setApiKey”）
你曾经面对过这个问题吗？

      title: "Cool Photo App Camera Permission",

        "so you can take awesome pictures.",
