Summary of Changes

Hello @fulleni, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refactoring the authentication module's UI logic by simplifying a buildWhen condition. The intent is to streamline how the user interface reacts to changes in the authentication status, ensuring that the UI rebuilds whenever the status transitions, without being constrained by specific status values.

Highlights

• Authentication UI Logic: The buildWhen condition within the BlocBuilder in _RequestCodeView has been simplified. It now triggers a rebuild whenever the AuthenticationStatus changes, removing the previous, more restrictive checks for specific status values (initial, requestCodeInProgress, failure).
• Code Refactoring: The change removes unnecessary complexity from the buildWhen predicate, making the UI's reaction to authentication state changes more general and potentially more robust by ensuring all status changes are considered for a rebuild.

Code Review

This pull request simplifies the buildWhen condition in RequestCodePage. The change makes the code more concise by removing specific status checks. My review suggests a further refinement to the condition to make it more performant by only rebuilding when the UI-affecting state actually changes, which aligns with the best practices for using buildWhen in flutter_bloc.
