I had a similar issue with Firebase realtime database, where once the app goes offline there was a console log spam (caused by fb attempting to establish connection), where I had to use .goOffline() method provided by the SDK to prevent it. 我在Firebase实时数据库中遇到了类似的问题，即该应用程序离线后，就会出现控制台日志垃圾邮件（由fb试图建立连接引起），在该应用程序中，我必须使用SDK提供的.goOffline（）方法来阻止它。
With Firestore SDK there are similar methods: 使用Firestore SDK，有类似的方法：
- Disable: https://firebase.google.com/docs/reference/js/firebase.firestore.Firestore.html#disablenetwork 禁用： https : //firebase.google.com/docs/reference/js/firebase.firestore.Firestore.html#disablenetwork
- Enable: https://firebase.google.com/docs/reference/js/firebase.firestore.Firestore.html#enablenetwork 启用： https : //firebase.google.com/docs/reference/js/firebase.firestore.Firestore.html#enablenetwork
Which you could call programmatically in the online/offline network listener callback. 您可以在联机/脱机网络侦听器回调中以编程方式进行调用。 If you can share your particular implementation I could help you show how. 如果您可以共享您的特定实现，那么我可以帮助您展示如何实现。
