FlutterFlow

Drag-drop interface for composing Flutter widget trees from a palette of 200+ pre-built widgets (buttons, forms, lists, cards, etc.) onto a canvas. Each widget's properties (colors, fonts, spacing, constraints) are edited via a property inspector UI that generates corresponding Dart property assignments. Real-time preview renders the widget tree in the browser using Flutter's rendering engine, with hot-reload capability for instant feedback during development.

Node-based visual programming interface for defining app logic without code. Users connect nodes representing conditions (if-then branching), API calls, state mutations (variable assignments), and custom Dart functions into directed acyclic graphs. The editor compiles these visual flows into Dart code that executes on user interactions (button taps, form submissions, etc.). Supports complex branching, loops, and error handling through visual node composition.

Test apps on iOS/Android emulators or physical devices connected via USB without deploying to app stores. Users can run the app locally, interact with it, and see changes in real-time (hot reload). Supports debugging via browser DevTools or Android Studio debugger. Requires Android SDK/iOS SDK installed locally.

Automatically generate test cases for app screens and interactions, and execute them to validate functionality. Tests are generated based on the visual composition and action flows (e.g., 'tap button → verify API call → check UI update'). Tests are executed in a headless environment and report pass/fail status. Limited to 3 tests per project on Business tier.

Escape hatch for complex logic that cannot be expressed visually. Users can write custom Dart functions and inject them into action flows, or create custom Flutter widgets for advanced UI. Custom code is integrated into the exported source code and can be modified post-export. Supports importing external Dart packages via pubspec.yaml.

Create custom UI components (combinations of widgets with predefined properties and logic) and reuse them across multiple screens and projects. Components are stored in a library and can be instantiated with different property values. Changes to a component definition automatically update all instances across the app. Supports component versioning and deprecation.

Write and deploy Google Cloud Functions directly from the FlutterFlow IDE without leaving the platform. Users can create serverless backend functions (e.g., API endpoints, scheduled tasks, webhooks) and deploy them to Google Cloud. Functions are triggered from action flows (e.g., button tap → call Cloud Function → update UI). Requires Google Cloud project and billing.

Automatic layout adaptation for different device sizes (mobile, tablet, desktop) and orientations (portrait, landscape). Users define layouts once, and the system generates responsive Dart code using Flutter's layout constraints and media queries. Property inspector includes device-specific overrides (e.g., different button size on tablet vs phone). Real-time preview shows how layouts adapt to different screen sizes.

LLM-powered code generation that creates Flutter screens, components, and logic from text descriptions. Users describe a desired UI or interaction (e.g., 'create a login form with email and password fields, validate on submit, call /api/login endpoint') and the system generates corresponding widget composition, property assignments, and action flows. The underlying LLM model is not disclosed; generation is rate-limited by tier (5 lifetime on Free, 50-500/month on paid tiers).

Built-in connectors for Firebase (Firestore, Realtime DB, Auth, Cloud Functions, Storage) and Supabase (PostgreSQL, Auth, Vector search) that allow users to bind UI widgets to backend data without writing backend code. Users configure data sources visually (select collection/table, filter, sort), and the system generates Dart code that fetches, caches, and syncs data. Supports real-time listeners for live data updates and automatic UI re-rendering on data changes.

Allows users to connect to any REST API by providing endpoint URLs or importing OpenAPI/Swagger specifications. The system parses the schema and generates Dart code for HTTP requests, response parsing, and error handling. Users can call APIs from action flows (e.g., button tap → POST /api/login → handle response) and bind responses to UI widgets. Supports authentication headers, request/response transformation, and error handling.

One-way import of design systems from Figma files, extracting colors, typography, and component definitions into FlutterFlow's design system. Users select a Figma file, and the system maps Figma styles (colors, text styles, components) to Flutter equivalents. Once imported, the design system is available in the property inspector for consistent styling across all screens. Changes to the Figma design system do not automatically sync back to FlutterFlow.

One-click export of the entire app as Flutter/Dart source code, including all widgets, logic, data bindings, and API integrations. Exported code is clean, readable, and maintainable — not minified or obfuscated. Users can download the source, open it in VSCode or Android Studio, and continue development using standard Flutter tooling. No proprietary runtime or vendor lock-in — exported code is fully portable.

Automated deployment pipeline that builds APK/IPA files and submits them directly to Google Play Store and Apple App Store without users needing to manage signing certificates, provisioning profiles, or build configurations. Users provide app metadata (name, description, screenshots, pricing) and FlutterFlow handles the rest: code signing, build optimization, and store submission. Supports multi-language localization via Google Translate integration.

Publish Flutter web apps to custom domains (e.g., myapp.com) without managing hosting infrastructure. FlutterFlow handles server provisioning, SSL certificates, and CDN distribution. Users configure custom domain DNS settings, and the system automatically deploys the web app. Supports multi-language web apps via Google Translate integration.

Multiple team members can edit the same FlutterFlow project simultaneously, with real-time synchronization of changes (widget additions, property edits, logic changes). Supports branching (2-5 open branches depending on tier) for parallel development of features. Changes are merged back to the main branch, with conflict resolution handled by the system. Includes comments and task assignment for team communication.
