CRUD Operations with the Firebase Realtime Database in Flutter

A Guide to Storing and Syncing Data in Realtime

Firebase is a popular backend service that provides a realtime database for storing and syncing data across multiple clients. In this post, we’ll learn how to use the Firebase Realtime Database in a Flutter app to store and retrieve data in realtime.

Setting up a Firebase project and adding the Realtime Database to a Flutter app

Before we can start using the Firebase Realtime Database in our Flutter app, we need to set up a Firebase project and add the Firebase Realtime Database to our app. Here’s how to do it:

1. Go to the Firebase console and create a new project.
2. Click the “Add Firebase to your Android app” or “Add Firebase to your iOS app” button (depending on which platform you’re developing for) and follow the prompts to set up your app in the Firebase console.
