Dart jobs

I’m expanding our mobile team and want an experienced developer who is equally comfortable in Flutter (Dart) and React Native (JavaScript/TypeScript). Our live products run on both iOS and Android, so every feature you tackle must compile cleanly and perform smoothly on each platform from the first build. THIS JOB IS IN THE US TIME ZONE ONLY + NEED WEEKEND AVAILABILITY The initial assignment is urgent—bug squashes and a small new module need to ship ASAP—yet the larger goal is an ongoing collaboration. Once we clear this immediate milestone together, you’ll roll straight into our regular sprint cycle, building new screens, integrating REST/GraphQL APIs, writing unit tests, and taking part in code reviews on GitHub. To get a quick read on your fit, please l...

...front-end and Laravel back-end source, along with current store credentials. What I need now is a hands-on developer who can streamline the online payment flow—specifically, cut down the transaction time from the moment a customer taps “Pay” until confirmation appears—then produce fresh production builds and submit them to both stores. Scope of work • Review the existing Flutter checkout screens, Dart services, and the Laravel payment API. • Pinpoint and refactor any latency bottlenecks (network calls, serialization, DB look-ups, third-party SDK latency, etc.). • Where viable, introduce caching, parallel requests, or optimized queries so the entire payment round-trip feels markedly faster to end users. • Keep current payment ga...

...improving the current Flutter codebase so the UI feels smoother and the overall performance is more consistent across Android and iOS. On the server side, the Laravel project requires the same depth of care—refactoring where necessary, tightening security, and making sure every existing endpoint responds quickly and reliably to the updated client. You will have direct access to: • Flutter project repo (Dart, latest stable channel) • Laravel 9 repo (PHP 8+, MySQL) Deliverables • Updated Flutter project that compiles without warnings and runs on both major platforms • Refreshed Laravel code pushed to the main branch, with all unit tests passing • Brief change log summarising what was touched on each side of the stack Acceptance criteria 1.

I need a senior-level Flutter engineer (5 + years hands-on) to take charge of a peer-to-peer mobile application that must run seamlessly on both iOS and Android from a single codebase. The core job is to own feature development end-to-end: architecting clean Dart code, wiring up real-time data flow, refining UI components for multiple screen sizes, then shipping fully tested builds to the App Store and Google Play. The project already has a high-level product roadmap; you will turn that vision into production-ready widgets, state management (Bloc or Provider is fine), secure API integrations, and smooth animations. Regular collaboration with our designer and back-end team happens in Slack and Jira, with code reviews in Git. I release milestones every two weeks, and each sprint shou...

I already have a working Flutter project that runs perfectly on my Dev AI box. The next step is polishing it for real-world distribution. The job in a nutshell • Tidy up the existing Dart code so it scales cleanly across phones and tablets without layout glitches. • Track down and solve the Play Store build issue where the release APK cannot detect network connections that work fine in debug. Any permission, manifest or network-security-config adjustments are fair game as long as they keep the codebase neat and maintainable. • Build, sign and upload final releases to both Google Play Console and Apple App Store Connect, passing their standard checks and review. Typical tools in play will be Flutter 3.x, Android Studio, Xcode, App Store Connect, Play Console an...

What I need from you is a fast, reproducible diagnosis, a clean code fix (whether in Dart, the REST endpoint, or both), and a short hand-off note so my team understands the root cause. Please come with solid debugging habits—Charles/Proxyman, Flutter DevTools, Postman, whatever gets you to a reliable solution—and be ready to test on bo...

...every five feed items a native ad should appear, matching the app’s current look and feel so users experience it as part of the content rather than a banner. I do not yet have the specific Native ad-unit ID, so I’ll need you to walk me through creating it in the AdMob console and wiring it up in code. The project is straightforward: plug the Google Mobile Ads SDK into my existing Flutter codebase (Dart), build a widget that pulls and renders the Native ad, place it in the list adapter, then verify that test ads show up reliably on both Android and iOS builds. When we’re done I expect: • Updated Flutter source with clearly commented integration • One or two short code snippets showing how to control ad frequency in case I adjust it later • St...

I have a live website built with Dart/Flutter for the web, and I now need it packaged as a fully working Android APK while giving the interface a fresh look. The new styling should cover the entire color scheme—backgrounds, fonts, and buttons—along with updated typography that feels consistent across pages. I also want the layout streamlined: the navigation menu needs a cleaner structure, content blocks should align responsively on all screen sizes, and the footer should be reorganised for better usability.

I have a polished mobile UI ready and now need it brought to life for both iOS and Android. The core build will live in Flutter and Dart so that we share as much code as possible, yet some portions may call for platform-specific polish—think buttery-smooth animations or native widgets that demand Kotlin on Android or Swift on iOS.
