Dart Jobs

Building a new mobile app in Flutter and I need a developer who already has three to four solid years working with the framework and, in particular, with the BLoC state-management pattern. The project targets both iOS and Android from a single codebase, so your experience shipping apps to the App Store and Google Play will matter. You will take charge of the full Flutter layer: setting up the architecture with clean, well-documented BLoCs, wiring up screens, and ensuring smooth performance on each platform. A clean folder structure, readable Dart code, and clear separation of concerns are non-negotiable, as this codebase will grow over time. Typical day-to-day work will include: • Converting Figma (or comparable) designs into responsive Flutter widgets • Implementing new feat...

I’m expanding our mobile team and need a Flutter front-end developer who can take full ownership of the customer-facing side of a new e-commerce app. The work is 100 % Flutter, so solid Dart fundamentals and at least two years of hands-on experience are non-negotiable. You’ll be shaping every screen in line with our in-house Custom Design System, not off-the-shelf Material or Cupertino components, so an eye for detail and comfort with bespoke styling is essential. Scope of work You’ll turn Figma mock-ups into smooth, production-ready code, wire the UI to the REST endpoints our back-end team exposes, and make sure performance holds up across Android and iOS. While the app may later grow into social or utility features, your immediate focus is strictly e-commerce. Core ...

I have a complete Figma design for an crypto mobile application and now need it built in Flutter and published under your own Google Play developer account. The core goal is to move from design files to a live, downloadable Android app that meets Google’s current policy requirements.

Because the purpose of this project is strictly crypto, smooth product browsing and purchasing flow must remain central throughout your implementation. Deliverables • Fully functional Flutter project (Dart source, assets, ) matching my approved UI • Release-ready AAB signed with your Play signature, plus a debug build for testing...
