About this gig
Need a FlutterFlow developer to turn your idea into a working Android or iOS app?
I build responsive FlutterFlow mobile apps and MVPs for startups, founders and businesses. I can handle the UI, app logic, backend and integrations so you get one organized project instead of juggling several freelancers.
I can build:
· Startup MVPs and SaaS apps
· Booking, marketplace and ecommerce apps
· Delivery, social, chat and community apps
· Fintech, education, restaurant and custom business apps
Services include FlutterFlow development, Flutter/Dart custom code, Firebase or Supabase, authentication, database setup, REST API integration, payments, push notifications, admin dashboards, Figma-to-app conversion and Android/iOS deployment support.
You receive responsive screens, clean workflows and FlutterFlow project/source access based on the agreed package.
Please message me before ordering if your app needs complex APIs, AI, maps, subscriptions, multi-vendor logic or advanced admin features so I can confirm the correct scope.

FAQ
Can you build for both Android and iOS?
Yes. I build cross-platform FlutterFlow apps for Android and iOS and configure responsive layouts for the required devices.
Can you build an MVP for my startup?
Yes. I can build a lean MVP around your core user flow so you can test the idea, demonstrate it to stakeholders and collect early feedback.
Do you work with Firebase and Supabase?
Yes. I can configure authentication, databases, storage and backend workflows using Firebase or Supabase depending on your project needs.
Can you integrate REST APIs and third-party services?
Yes. Please provide the API documentation or service name. I can integrate supported REST APIs, payment services, maps, AI services and other third-party systems after reviewing the scope.
Can you convert my Figma design to FlutterFlow?
Yes. I can recreate your Figma screens in FlutterFlow and connect the required navigation, backend and app logic.
Will I get the FlutterFlow project or source code?
Yes. Project/source access is provided according to the agreed package and any FlutterFlow plan requirements that apply to code export.
Can you publish the app to Google Play and the Apple App Store?
Yes. I can provide submission and deployment support. You must provide the required developer accounts, store information, privacy details and assets. Store approval is controlled by Google and Apple and cannot be guaranteed.
Can you add payments, subscriptions and push notifications?
Yes. These can be included in the appropriate package or added through a custom offer after the required provider and workflow are confirmed.
Can you improve or fix an existing FlutterFlow project?
Yes. Send the existing project details and a clear list of bugs, UI changes or features you want added so I can review the scope.
Should I contact you before ordering?
Yes, especially for apps with backend logic, APIs, payments, AI, maps, dashboards or more screens than the package includes. This prevents scope and delivery-time misunderstandings.
