Flutter Grocery App UI Revamp

I’m overhauling the user interface of my subscription-based grocery mobile application, which is already built in Flutter. The goal is purely to modernize the design and give every screen a minimalistic, clean aesthetic that feels effortless for shoppers racing through their weekly list. Functionally everything stays the same; what I need is a fresh visual layer and the accompanying Flutter code to make it real.

Scope
• Redesign all current screens: onboarding, home, product-search, cart/checkout, subscription management, order tracking, and profile.
• Produce updated, platform-compliant assets (icons, illustrations, typography, colour tokens) that follow Material 3 guidelines while keeping the palette light and uncluttered.
• Implement the new layouts directly in Flutter using best-practice architecture (widgets, themes, responsive breakpoints).
• Ensure smooth transitions/animations that do not compromise performance on mid-range Android or iOS devices.

Acceptance criteria
1. Every existing feature remains fully usable after the revamp.
2. New UI matches approved mock-ups pixel-perfectly on standard phone and tablet sizes.
3. Dark mode supported.
4. Code passes Flutter analyse and builds without warnings.
5. Delivery timeline: I’m aiming for an ASAP turnaround, so please outline how quickly you can start and a realistic milestone plan.

If this aligns with your skills, let’s modernize the app together so customers can enjoy a cleaner, faster shopping experience.
