带Firestore（21122）：（24.7.0）[WatchStream]：（6db 20 e0）流已关闭，状态为：状态{code=PERMISSION_DENIED，description=资源项目resturant的权限被拒绝。原因=null}。
每当我运行flutter应用程序时，它会在控制台中显示这条消息，而且它不会从数据库中获取任何数据。

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write;
    }
  }
}

我试过了，但是没有用。
