Firebase Core for Flutter: A Comprehensive Guide

Firebase Core for Flutter is a plugin that enables developers to connect to multiple Firebase apps within their Flutter applications. It provides a convenient way to manage and access Firebase services from a centralized location. In this guide, we will delve into the setup, usage, and key benefits of Firebase Core for Flutter.

Setup

To get started with Firebase Core for Flutter, follow these steps:

1. Add the plugin dependency to your pubspec.yaml file:
