Cloud Firestore helps us store data in the cloud. It supports offline mode so our app will work fine (write, read, listen to, and query data) whether device has internet connection or not, it automatically fetches changes from our database to Firebase Server. We can structure data in our ways to improve querying and fetching capabilities. This tutorial shows you a Flutter app that can do Firestore CRUD Operations with ListView widget.
