One Flutter codebase, both app stores
Flutter is our home ground - 3+ years of Flutter and FlutterFlow work across mobile, web, and Firebase-backed products, delivered by developers who work in it daily.
What this service covers
Flutter lets a single Dart codebase ship polished apps to Android and iOS at once - roughly one build instead of two, without the compromises of older hybrid frameworks. XCoder has specialised in Flutter and FlutterFlow for over three years, and our founder-led team has delivered Flutter work for clients internationally, including through top-rated freelance engagements.
We handle the full stack around the app: Firebase and Supabase backends, authentication, real-time databases, REST API and payment gateway integration, state management with GetX, and store-ready release builds. For fast-moving projects, FlutterFlow lets us assemble production apps at low-code speed while keeping full code ownership - and every project transfers to you completely on final payment.

Common questions about flutter development
Flutter ships one codebase to both Android and iOS with native-feeling performance, which typically means lower cost, faster delivery, and easier maintenance than building two separate native apps.
Yes - we build both. FlutterFlow is ideal for fast, budget-conscious launches, and hand-written Flutter for complex, fully custom apps. In both cases you own the code.
We work on simple fixed-quote terms: 50% advance to start the project and 50% before final delivery. Full ownership of the code and design transfers to you on final payment, and every project includes one month of free maintenance.
