Flutter: One Codebase, Five Platforms

Flutter in 2026 is the most productive way to ship mobile apps. One Dart codebase → iOS, Android, web, macOS, Windows, and Linux. Google's material design components, custom rendering engine, and near-native performance have made Flutter the #1 cross-platform framework for new mobile projects.

For SaaS builders, Flutter's multi-platform output is particularly compelling — ship a native mobile app and a web app from the same code.

The Starters

ShipFlutter — Best Complete Mobile SaaS

Price: $149 (one-time) | Creator: IndependentDevs

The most complete Flutter SaaS boilerplate. Firebase or Supabase auth (your choice), RevenueCat for in-app purchases, Stripe for web billing, push notifications, analytics, onboarding flows, settings screen, dark mode, localization, and CI/CD config for App Store and Play Store.

Key features:

Firebase Auth + Firestore or Supabase Auth + PostgreSQL
RevenueCat integration (in-app purchases, subscriptions)
Stripe webhook handling for web payments
Push notifications (FCM)
Remote config / feature flags
Analytics (Firebase Analytics / Mixpanel)
App Store Connect + Play Console release automation

Choose if: You're building a mobile-first SaaS and want everything set up.

Very Good CLI — Best Production Architecture

Price: Free | Creator: Very Good Ventures

Created by Flutter's premier agency (VGV), this CLI generates Flutter apps with their opinionated architecture: Bloc state management, 100% code coverage requirements, internationalization (ARB files), flavors (dev/staging/prod), and GitHub Actions CI.

# Install
dart pub global activate very_good_cli

# Create app
very_good create flutter_app my_app

# Create feature
very_good create flutter_feature auth

Choose if: Code quality, testing, and team scalability matter. VGV's architecture scales to large teams.

Flutter Firebase Starter — Best Free Firebase

Price: Free | Creator: Community

Flutter app connected to Firebase: Firebase Auth (email, Google, Apple), Firestore database, Firebase Storage, Firebase Analytics, and Crashlytics. The fastest way to get a Flutter app to production with Firebase.

Choose if: You're committed to Firebase and want a free, battle-tested starting point.

Flutter Supabase Starter — Best Free Supabase

Price: Free | Creator: Community

Flutter app with Supabase: Supabase Auth, PostgreSQL via supabase_flutter, real-time subscriptions, and Storage. Modern alternative to Firebase with SQL querying and self-hosting options.

Choose if: You prefer PostgreSQL over Firestore or want to avoid Firebase vendor lock-in.

Flutter's Architecture Considerations

State Management

Flutter's biggest architectural decision is state management:

Package	Approach	Complexity	Best For
Riverpod	Providers	Medium	Solo dev, medium teams
Bloc	Stream-based	High	Large teams, testability
Provider	InheritedWidget	Low	Small apps
GetX	All-in-one	Low	Rapid prototyping

ShipFlutter uses Riverpod. Very Good CLI uses Bloc. Both are valid — pick based on team preference.

Mobile Billing

Flutter has two billing paths:

RevenueCat — Cross-platform in-app purchase management. Handles iOS StoreKit, Android Billing Library, and web Stripe in one SDK. The standard choice for monetized Flutter apps.
in_app_purchase — Flutter's official IAP plugin. More control, more code. Good for teams that want to manage subscriptions directly.

When to Choose Flutter

Flutter is the right choice when:

You need iOS + Android from one codebase
Native-like performance is required (Flutter renders with Skia/Impeller, not webviews)
You want to add a web or desktop app later from the same code
Your team is willing to learn Dart (most developers pick it up in 1-2 weeks)

Consider React Native when:

Your team is deeply invested in React/JavaScript
You need to reuse existing React components
Expo's OTA updates are important to your workflow
