Flutter Marketplace Listing App

I’m building the first release of a marketplace-style e-commerce app and I need a Flutter developer who can focus exclusively on the catalogue side of things. For this phase the scope is narrow: create a smooth, production-ready product-listing experience that can sit at the heart of a multi-vendor marketplace later on.

Here’s what I need built:
• A product list view wired to a real or mock back-end, able to display hundreds of items without jank
• Category navigation that lets shoppers drill down quickly
• Robust search with filters (price, tags, or any meta data we define) and clear empty-state handling
• Clean, themeable UI that follows Material 3 guidelines and is ready for light / dark modes
• Well-structured, documented code so future modules—vendor dashboards, checkout, payment gateways—can slot in without rewrites

Please use modern Flutter best practices (Riverpod or Bloc for state, null-safety, responsive layouts). Submit the full Dart source, a brief setup guide, and a short screen-recording that proves search and category filtering work on both Android and iOS emulators.

If you enjoy building elegant UI and performant lists, let’s get this core piece shipped so we can move on to the fun stuff like payments and vendor tools in the next milestone.
