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 the link below to learn more about Firebase projects.
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.
