Firebase Configuration

Create a Firebase project

Before you can add Firebase to your Flutter app, you need to create a Firebase project to connect to your app. Visit Understand Firebase Projects to learn more about Firebase projects.

Important:

If you're releasing your Flutter app on both iOS and Android, register both the iOS and Android versions of your app with the same Firebase project.
