SparkMatch: Flutter Dating App Template with Swipe Matching, SparkMatch+ Paywall and Verification

SparkMatch is a working dating app, not a folder of static screens. Unzip it, run it, and the full swipe-to-chat loop is already there: discovery, matching, messaging, and a premium upsell path, all wired together and demoable from the first launch. Think of it less as a dating app UI kit and more as a dating app starter kit: the discovery experience, the monetization screens, the safety 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. It ships with a deep rose and violet love palette and a separate champagne gold reserved only for premium and verified moments, so upgrading and getting verified both read as distinct, intentional visual events rather than one flat accent color doing every job.

Discovery and Matching

•      Drag-to-swipe discovery deck with like, pass, and Super Like, plus tap-to-view full profiles

•      Deterministic mutual matching, so testing the app always produces a realistic mix of matches

•      Rewind to undo your last swipe, gated behind SparkMatch+

•      An AI Match compatibility score on every profile, backed by a transparent local formula rather than a trained model

SparkMatch+ Premium

•      A Who Liked You screen: candidates who already liked the user first, shown blurred and locked until upgrading

•      A premium paywall screen with monthly and yearly plan options

•      Rewind and Who Liked You are both gated behind the same local SparkMatch+ flag

•      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

Profile and Trust

•      An editable profile with photos, bio, interests, and Hinge-style prompt questions

•      A simulated photo verification flow that adds a verified badge next to a profile

•      Report and block actions available from any profile or conversation

Matches and Messaging

•      A matches list with unread indicators and a per-match last message preview

•      In-app chat, with new matches sending a short simulated opening line

•      A built-in support chat powered by a local rule-based assistant, clearly labeled as automated and never presented as a real match or a real person

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 Discover through the SparkMatch+ paywall, is already populated and functional.

Every seeded profile, including the guest profile, uses real photography pulled from Unsplash’s free, commercially licensed photo library at runtime rather than bundled as local files. These are stock model photos meant only to make the demo feel populated. They are not the likeness of anyone actually using this app, and pairing a real, identifiable person’s photo with a fabricated name, age, and bio is a use that a standard stock license was not written for. Replace every seeded photo with real user photos, or your own properly licensed placeholder set, before letting any real person swipe on 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 18 seeded discovery profiles plus a guest profile, with real stock demo photography

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

•      The full SparkMatch+ flow: Who Liked You, the premium paywall, gated Rewind, and profile verification, 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 (discover, likes, matches,messages/chat, profile, premium, verification, preferences, safety, auth, settings, shell)  

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

services/      match_service.dart, the local AI Match scoring 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 backend (or BaaS) for matching and chat, a real payment or subscription integration for SparkMatch+, push notifications, and a moderation/reporting layer, all connected through the existing repository layer • Before inviting real users: replace every seeded demo photo (see Full Description) with real user 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 • Swipe-deck, grid, and list layouts hardened against text/content overflow across phone sizes and font scales • SparkMatch+ gating (Who Liked You, Rewind) is a local demo flag, not a real subscription or store billing integration (see Requirements)
