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.

Simple Android OBD-II Diagnostic App

I need an Android application that pairs with an ELM327 Bluetooth OBD-II adapter and performs a very limited set of diagnostic tasks. The goal is to give me a clean, lightweight tool rather than a full-blown scanner. Core behaviour • When the user taps “Connect”, the app must discover and bond with a standard ELM327 device and keep the link alive. • Once connected, it should read live PIDs for engine RPM and battery voltage/status and refresh them smoothly on screen. • A single button should read any stored trouble codes and, when pressed again, clear them. No additional graphs, logging or fuel-consumption features are required. Tech notes I am comfortable with you writing the project in either Kotlin or Java inside Android Studio; please use the standard Bluetooth APIs (or a lightweight library if it speeds development). PID queries can be hard-coded—no dynamic command builder is necessary. The interface can be minimal: two large numeric fields for RPM and battery, plus the read/clear button. Deliverables Full Android Studio project with well-commented source. One signed release APK I can load directly onto my phone. A short README explaining how to pair the adapter and which PIDs you used. Acceptance I will test by pairing the app with my own ELM327 dongle; connection must succeed within 10 seconds, RPM values should update at least twice per second, and clearing codes must return the standard success response. If this sounds straightforward to you, let me know your timeline and any questions you have.
