Yes, it work also with Firestore. As the offical documentation says,

Cloud Firestore supports offline data persistence. This feature caches a copy of the Cloud Firestore data that your app is actively using, so your app can access the data when the device is offline. You can write, read, listen to, and query the cached data. When the device comes back online, Cloud Firestore synchronizes any local changes made by your app to the data stored remotely in Cloud Firestore.

To be more clear, every client that is using a Firestore database and sets PersistenceEnabled to true, maintains it's own internal (local) version of the database. When data is inserted/updated, it is first written to this local version of the database. As a result, all writes to the database will trigger local events immediately, before any data has even been written to the server. This means that the app will remain responsive regardless of Internet connectivity.

So, feel free to use Firestore offline capabilities.
