Resolving Flutter Firebase Auth Version Update While Retaining the StreamProvider

Updating dependencies in a Flutter application can sometimes feel like navigating a minefield, especially if breaking changes occur. If you find yourself in the situation of needing to update the Firebase Auth plugin from version 0.15.5+ 3 to 0.18.3, yet want to retain the functionality of your StreamProvider for user authentication, you’re not alone. This guide will walk you through the steps necessary to achieve this successfully.

Understanding the Problem

When Flutter's firebase_auth plugin was updated, significant breaking changes were introduced that could disrupt existing code. A common pain point noted by many developers is how to handle user authentication streams efficiently while transitioning from the earlier version to the more recent one.

Ensuring seamless access to the authenticated user throughout the application.

Step-by-Step Solution
