    ...and database change we discussed in chat. After reviewing it together, the next step is to build the add-on that extends my current Flutter mobile app and the accompanying Laravel admin panel. Here’s what I need completed: • Implement the new Flutter screens, widgets, and business logic exactly as outlined in the PDF, keeping full compatibility with the existing app architecture (Flutter 3.x, Dart). • Expand the Laravel 10 backend—routes, controllers, models, and migrations—for the extra data points and transactions detailed in the document. • Update the admin panel so the new records can be created, edited, filtered, and reported without breaking any current functionality. • Maintain the coding conventions already in place, include c...

    I have the core concept for a new application and have decided to build it entirely in FlutterFlow. I’m looking for someone who already knows their way around this no-code/low-code builder—someone who can move quickly from screen layouts to fully func...logic. I’ll provide wireframes, brand assets, and a shortlist of third-party APIs as soon as we kick off. You’ll handle setting up the project, wiring the UI to data, configuring Firebase, testing on both platforms, and handing me a working build I can submit to the App Store and Google Play. If you’re comfortable with FlutterFlow’s visual builder, Firebase integration, and the occasional Dart tweak when the visual tools hit their limits, let’s talk. I’m ready to get started as so...

    ...our own internal standards while building the project; however, those rules live mostly in our heads rather than in formal documentation. That means I need someone who can dive straight into the source, interpret our style from context, and benchmark it against recognised best practices. The audit has three clear pillars: code quality, performance, and security. I expect a thorough review of the Dart/Flutter codebase, dependency tree, build configuration, and native platform integrations. On the performance side, I’m looking for concrete findings backed by profiling data—startup time, rendering speed, memory usage, and any platform-specific bottlenecks. Security concerns should include common mobile attack vectors, data storage & transmission, and third-party pac...

    This project delivers a mid-fidelity frontend prototype for a digital-health research app built with Flutter and Dart. The goal is strictly UI/UX validation; there is no backend integration or persistent data storage in this phase. The build must run smoothly on both Android and iOS. I will supply the design guidelines that drive color, typography, spacing, and component behaviour, and expect you to translate them into accessible, responsive Flutter widgets. Key screens include the onboarding series, an email-and-password sign-in flow (UI only), multi-step questionnaire and survey views, plus reminder and notification concepts. Smooth navigation, basic state handling, and adherence to accessibility best practices are all part of the brief. Deliverables • A runnable F...

Pairing succeeds at the OS level, yet nothing prints from the app and no error is thrown in the console. What I need is a clean, reproducible fix for both problems along with a brief explanation of what caused them so we can avoid regressions later. Deliverables • Updated Flutter/Dart code (or a pull request) that eliminates the post-transaction crash. • Working Bluetooth print workflow, tested from the same build of the app. • A concise changelog or README note outlining the modifications and any package or SDK updates required.
