Flutter Layout Rearrangement Needed

I have a working Flutter app whose look and feel I’m generally happy with—colors, fonts, icons, everything can stay as is. What I do need is a fresh, cleaner arrangement of the widgets that are already on each screen. In short, the job is purely about reorganising the current components, not creating new artwork or altering the theme.

Here’s what I’m after:
• Review the existing Dart code and propose a more intuitive flow for each screen.
• Update the widget tree so that buttons, images, text fields and other current elements are placed in a more user-friendly order.
• Keep the app fully responsive across common phone and tablet sizes.
• Return well-commented Dart files (or pull-request) so I can follow your logic easily and continue maintaining the codebase.

No assets need redesigning, no new typography, just a thoughtful layout pass that improves usability. If you’ve streamlined Flutter screens before and can turn this around quickly, I’d love to see your approach and estimated timeframe.
