Developer Guide: FlutterFlow for Engineers

Custom Actions & Widgets

Extend FlutterFlow's capabilities by writing custom Dart code. Custom Actions let you run arbitrary Dart logic triggered by the Action Flow Editor. Custom Widgets allow you to embed fully custom Flutter widgets into your visual layout.

Code Export

Export your entire project as a standard Flutter project at any time:

  • Navigate to Developer Menu → Download Code
  • The export produces a standard pubspec.yaml, widget tree, and Dart source files
  • Continue development in any IDE (VS Code, Android Studio) using standard Flutter tooling

REST API Integration

  1. Navigate to API Calls in the left sidebar
  2. Define endpoints, set headers, query params, and body schemas
  3. Map response JSON fields to FlutterFlow variables or state
  4. Call the API from the Action Flow Editor on any trigger

Firebase & Supabase Setup

  • Firebase: Connect via the Firebase panel — FlutterFlow auto-generates Firestore collections, Auth flows, and Cloud Function triggers
  • Supabase: Link your Supabase project URL and anon key; FlutterFlow generates table-aware CRUD queries visually

Figma Import

Import design tokens, color styles, and component themes directly from a Figma file URL to keep your FlutterFlow project in sync with your design system.
