如果您对如何解决此问题有任何想法，请告诉我...提前致谢！
【问题讨论】：
【参考方案1】：我相信这可能是一个同步问题，因为您的 onAddPatient 函数是一个异步函数，但您没有等待 firestore 添加文档，这会产生意外状态。要修复它，您只需要等待它，所以：
onAddPatient = async () =>
await firebase.firestore().collection("Patients").add(
patientName:this.state.patientName
)
【讨论】：
嘿！您提供的解决方案对我有用，但现在我在其他屏幕上遇到了同样的错误。我个人认为这是因为 onSnapshot 函数...我会将该代码添加到问题中...但是非常感谢您！ @Vibha 我看到这是你在堆栈上的第一个帖子，所以首先，欢迎。我建议您将此作为一个单独的问题发布，因为现在我提供的答案（您提到的正确）不再有效，因为您更改了问题的代码，并且如果社区中的其他人遇到同样的问题，因此，他们将无法看到如何应用该解决方案。如果您想使用更多代码提出后续问题，您可以这样做（尽管最好发布一个单独的问题），但您必须保留原始代码。 另外，您可以阅读此article，了解当有人回答您的问题时该怎么做。 非常感谢@Rafael Lemos 如果它解决了您面临的问题，请考虑接受/投票。以上是关于使用 firestore 时出现以下错误错误：FIRESTORE (8.1.2) INTERNAL ASSERTION FAILED: Unexpected state的主要内容，如果未能解决你的问题，请参考以下文章
