Flutter Revamp & Laravel API

I already have a live Flutter app backed by a Laravel-PHP server. I need to move fast on a small but important upgrade cycle. First, the front-end. I want the current screens re-laid out so they feel lighter and more intuitive; that means rearranging widgets, spacing, and visual hierarchy...
