Developer Documentation
Code Export
FlutterFlow generates idiomatic Flutter/Dart code that you can export at any time via Project Settings → Export Code. The exported code is clean, structured, and ready to open in any Flutter-compatible IDE (VS Code, Android Studio).
Custom Widgets & Actions
When the visual builder reaches its limits, developers can write raw Dart code:
- Custom Widgets: Create Flutter widgets in Dart and register them in the FlutterFlow UI for use on any canvas page.
- Custom Actions: Write Dart functions triggered by Action Flow events — useful for complex business logic, third-party SDK calls, or device APIs.
API Integrations
Project Settings → API Calls → Add API Call
- Method: GET / POST / PUT / DELETE
- Base URL + endpoint path
- Headers, query params, and JSON body (supports dynamic variables)
- Response parsing with auto-generated data types
Firebase & Supabase Setup
- Connect Firebase by importing your
google-services.json/GoogleService-Info.plistdirectly in the FlutterFlow dashboard. - Supabase integration requires your project URL and anon key — Firestore collections and Supabase tables are auto-detected and mapped to FlutterFlow data types.
Branching & Collaboration
FlutterFlow supports Git-style branching within its platform. Team members can create feature branches, make isolated changes, and merge back — all without leaving the browser.
