GreenCart | Multi-Vendor Organic Grocery Marketplace Flutter App + Next.js

GreenCart Market is a 5-surface bundle: two Flutter apps (customer + rider) plus one Next.js 16 project that is the public storefront, the /vendor portal, the /admin panel, and the only backend. It is a vertical marketplace for organic / local / farm-to-table grocers, built on a modern TypeScript stack (Next.js + PostgreSQL + Drizzle) — not the PHP/Laravel platforms that dominate this category. Two differentiators the incumbents lack: subscription produce boxes and product provenance / sourcing. Highlights GreenCart Multi-vendor cart → per-vendor order split — one cart spanning many stores becomes one order + N sub-orders, each fulfilled, tracked, and settled independently. GreenCart  Product provenance / sourcing — every product carries a farm/origin “provenance card.” Subscription produce boxes — recurring weekly/biweekly boxes with skip / pause / resume. Live delivery tracking + a full rider app — turn-by-turn Google Maps navigation, proof-of-delivery photo, COD cash collection. Stripe + PayPal + COD — platform-collected, with real refunds. Commission ledger + vendor payouts — every sub-order records commission; balances accrue and settle per period. Vendor portal + super-admin panel — onboarding, products, payouts, coupons, KPIs, reports, CSV export, churn. AI recipe & seasonal picks — OpenAI or Gemini, server-side, rate-limited, with a mock fallback. “Modern Agrarian” design system — one Tailwind v4 theme + matching Flutter ThemeData, white-labelable at runtime.
