Sellgram: Flutter Social Shopping App Template with Shoppable Feed and Sellgram+ Seller Tools

Sellgram is a working social shopping app, not a folder of static screens. Unzip it, run it, and the full loop is already there: post to a feed, tag an item for sale, get discovered in Explore, message the seller, and close the loop from a seller-side dashboard. Think of it less as a social app UI kit and more as a social commerce starter kit: the feed, the storefront, the messaging, the seller tools, and the localization are already built, so you connect your backend and turn it into your own product instead of starting from a blank project.

Every screen sits behind a clean, abstracted repository layer built on Riverpod and go_router, with a rule-based support assistant, six built-in languages, and a color system you can restyle from a single file. Every seeded seller and every seeded listing photo now uses real stock photography matched to what it is showing, in place of the random placeholder images an earlier build shipped with, so the demo feed reads as a real marketplace rather than a wall of unrelated stock art.

Feed and Storefront

•      Instagram-style feed of posts, any of which can be tagged for sale with a price

•      Explore grid of every for-sale listing, with search by caption keyword

•      Post detail screen with likes, comments, and a Message Seller action

•      Follow/unfollow, with a live following count on your own profile

Sellgram+ Premium

•      A Sellgram+ paywall screen with monthly and yearly plan options

•      Boosted Listings: a Sellgram+ seller can pin any of their own listings to the front of the Explore grid, marked with a Boosted tag

•      A Sellgram+ badge next to the seller’s name on their own profile

•      One extra Engagement metric unlocked on the Seller Dashboard, alongside the existing listings/views/sales stats

•      The upgrade flow is demo only. Tapping Continue flips a local flag and never collects a card number or processes a real charge, which is called out on-screen and in Settings

Seller Dashboard

•      A seller-only Dashboard tab, unlocked automatically for any account that signs up as a seller

•      Add, edit, and delete your own listings from one screen

•      Deterministic demo stats (listings, views, demo sales) so the dashboard never looks empty during a demo, clearly labeled as not connected to real traffic

Messaging and Trust

•      Direct messages between shoppers and sellers, opened straight from a for-sale post

•      Simulated seller auto-replies so a fresh conversation never sits empty during a demo

•      A verified seller badge on select seeded profiles

•      A built-in support chat powered by a local rule-based assistant, clearly labeled as automated and never presented as a live agent

Languages and Accessibility

•      English, Arabic, Spanish, French, Turkish, and German

•      Full right-to-left layout, tested with Arabic

•      Automatic device-language detection with a manual override in Settings, no restart needed

Built for Developers

•      Flutter and Dart, Android and iOS from one codebase

•      Clean repository-pattern data layer, the same swap point used across the whole app template line

•      Local demo data; no backend or API keys required to run it

•      A centralized theme file for fast rebranding

No backend, database, or API keys are needed to see the whole app working: unzip the project, run flutter pub get and flutter run, and every screen, from the Feed through the Sellgram+ paywall and the Seller Dashboard, is already populated and functional.

Every seeded seller avatar and every seeded listing photo now pulls real photography from Unsplash’s free, commercially licensed photo library at runtime rather than the random placeholder images an earlier build used. These are stock photos meant only to make the demo feed and storefront feel populated. They are not the likeness of anyone actually using this app, and pairing a real, identifiable person’s photo with a fabricated seller name and bio is a use that a standard stock license was not written for. Replace every seeded photo with real seller and product photos, or your own properly licensed placeholder set, before letting any real seller or shopper use this app.

WHAT YOU GET

•      Complete Flutter source code (Android and iOS project structure)

•      All screens and navigation, wired to working state management

•      Local demo data covering 8 seeded profiles and 18 seeded listings, with real stock demo photography for every avatar and listing photo

•      Localization files for all 6 languages, including the Arabic RTL layout

•      The full Sellgram+ flow: the premium paywall, Boosted Listings, the profile badge, and the Dashboard Engagement metric, all demo only and payment free

•      A rule-based support chat implementation

•      A centralized, easy-to-edit theme file for rebranding

Not included: a custom app icon or splash screen artwork, a written setup guide, and any commercial rights to the demo photography beyond this template. The Full Description above explains exactly what to replace before a real launch.

ARCHITECTURE

If you’re buying source code, the code is part of the product. Here is the shape of it:

 | lib/  features/       one folder per screen/flow (feed, explore, messages, newpost, post, profile, seller, premium, settings, auth, chat, shell)  

data/   models/        plain data classes (PostModel, UserProfileModel, ...)   repositories/  abstracted data layer, ready for a real backend   

services/      ai_assistant_service.dart, the local support-chat logic  

core/   theme/         app_colors.dart, single source of truth for branding   localization/  strings_en.dart, strings_ar.dart + 4 more, plus lookup/fallback logic   

router/        all named routes (go_router)  providers/       Riverpod state providers

Requirements

• Flutter SDK 3.x and Dart 3.x installed • Android Studio or VS Code with the Flutter/Dart plugins • An Android emulator, iOS simulator, or physical device • No server, database, or API keys needed to run the demo; all data ships as local seed data behind a repository interface • To go live: your own content/commerce backend, a real payment or subscription integration for Sellgram+, a messaging service (e.g. Firebase, a custom socket backend), and a moderation layer, all connected through the existing repository layer • Before inviting real sellers or shoppers: replace every seeded demo photo (see Full Description) with real photos or your own properly licensed placeholder set

Compatibility

• Single Flutter codebase, builds to Android and iOS • Flutter 3.x / Dart 3.x (null-safe) • Full RTL layout support (tested with Arabic) alongside LTR • 6 languages built in, switchable from Settings • Feed, grid, and dashboard layouts hardened against text/content overflow across phone sizes and font scales • Sellgram+ gating (Boosted Listings, the profile badge) is a local demo flag, not a real subscription or store billing integration (see Requirements)
