Flutter app - repost 2 due to christmas

ENGAGEMENT TYPE Hourly (Time & Materials) Estimated effort: 22–26 hours total Start: Immediate Level required: Senior / Very Senior Flutter Developer ONLY WHAT THIS JOB IS (READ CAREFULLY) This is a small, precise repair task in an existing Flutter app. There is no greenfield work involved. There will be: No new features No refactors No architecture changes No redesigns No experiments No “suggested improvements” No “I found another bug” unless it can be reproduced locally You are fixing known, clearly scoped issues only. IMPORTANT BACKEND & API CONTEXT (NON-NEGOTIABLE) All APIs and server-side code have been working as late as December 2025. A full Postman collection exists and can be executed at any time to verify API functionality. The backend is Magento 2.4. No backend work is required. No Magento developer work is required. Stripe APIs are live and working. This task is Flutter-only. Any attempt to reframe this as a backend, API, or Magento issue is incorrect. REQUIRED SKILL LEVEL (MANDATORY) You must be: A Senior or Very Senior Flutter developer Comfortable fixing Stripe and Apple Pay issues in production apps Able to read existing code and fix it without rewriting it Able to work independently without supervision If you are not senior, do not apply. NON-NEGOTIABLE ENGINEERING RULE Never update Flutter, packages, or plugins before the existing code is confirmed working. This is a basic rule, yet one that many so-called “senior” developers still get wrong. IMPORTANT CONTEXT (PLEASE READ) The app already compiles. A previous developer requested payment before automated tests were run. That is not acceptable under PPH standards. Testing comes first. Payment comes after. For this reason, the previous contract was terminated. This is shared for clarity so expectations are fully aligned. APPLICATION FILTERS (STRICT) If you present web pages as Flutter references, you are not of interest. If you have no verifiable references, you are not of interest. If you describe yourself as a “full-stack developer”, you are not of interest. If you over-explain, bloat, or try to over-engineer, you are not of interest. I am looking for a specialist, not someone who knows a little about everything. This is a razor-sharp task. Change existing code. Nothing more.

Complete InDriver-Style Flutter App (Bidding System) for Study

I would like to take this opportunity to honestly explain the context of my request. I am currently a university programming student, and I am about to take a very important practical exam related to the analysis of a complete InDriver-style system. The goal of this exam is not just to see screens, but to deeply understand the source code, project architecture, ride flows, the bid/price negotiation system, map integration, backend logic, and the administrative panel. For this reason, it is essential that the system is truly functional, even if only in test mode. I need to be able to run the project, explore the flows, and study the full logic behind it. I want to be completely transparent:

Gui and save realtime process debugging code

I have two standalone Python scripts: • a real-time antenna control loop that streams data perfectly on its own, and • a small Tkinter interface with Start, Stop, and End buttons that also works when run separately. As soon as I merge them into a single file, the window still appears but none of the buttons respond. The antenna logic keeps running in the background, yet every GUI click is ignored, so I end up force-closing the app. I’m looking for someone who can: 1. inspect the merged code, identify why the Tkinter callbacks aren’t firing (likely event-loop or thread conflict), 2. refactor or restructure it so the GUI remains responsive while the antenna loop runs, and 3. hand back a single, clearly commented .py file plus a brief summary of what you fixed. The ideal result is: • Start → begins the real-time antenna routine; • Stop → pauses or safely halts that routine without freezing the window; • End → closes the program and releases any resources cleanly. and when u start to stop save the process as a file No need to alter antenna functionality—just make the integration solid and maintainable so I can learn from your approach.

.NET 8 MAUI macOS Installer Expert (ARM64 / Apple Silicon)

Summary We are looking for an experienced .NET developer with strong macOS deployment expertise to create a professional installer for an existing .NET 8 MAUI application. The application is already developed, and the primary goal is to package it specifically for macOS ARM64 (Apple Silicon) machines. Key Deliverables: 1- Production-Ready Installer: A fully functional .pkg or .dmg installer for the macOS ARM64 platform. 2- Source Script: The complete automation script (e.g., Shell script, PowerShell, or Azure DevOps/GitHub Actions YAML) used to generate the installer. 3- Documentation: A brief guide on how to run the script and any prerequisites (certificates, provisioning profiles, etc.) required for code signing and notarization. Requirements: - Deep understanding of .NET 8 MAUI and Mac Catalyst publishing. - Proven experience with macOS code signing and the Apple Notarization process. - Ability to handle ARM64-specific architecture identifiers (osx-arm64). Here is a video, as this will give you LOT better idea about our issue: https://drive.google.com/file/d/1indamIuFhIpwHFQgmpv08VFzXOZmKjkD/view?usp=sharing ---- NOTE: Please understand that we are also able to create a .DMG file, it is also installing but after installation, when we run the Application, certain control does not work. Similarly, on Windows, we are able to install and everything is working perfectly fine. Our assumption is that the Database path is not being picked when we install it on ARM64 / Apple Silicon BUT this is OUR ASSUMPTION, you can find the actual cause and resolve this issue. Payment ONLY on the successful completion & proof of work acknowledgement.
