Project Overview We are seeking an external contractor to develop a Flutter-based cross-platform system supporting the following platforms: Web (browser-based) Android App (APK) iOS App (IPA) The system is a pawn loan application system designed to allow the general public to submit loan applications to a pawn shop by filling in basic information. The mobile applications do not need to be published to Google Play or the App Store. Installation packages will be used for internal testing only. System Objectives and Scope Provide a loan application entry point (no instant lending or payment processing) Collect applicant basic information and device-authorized data Serve as a data source for backend review and risk assessment Mobile App Required Functions (Key Scope) The mobile applications must be able to obtain and transmit the following data only after explicit user authorization: The first five photos from the user’s device Contact list data Location data (GPS) Basic information form (e.g., name, phone number; exact fields to be confirmed during the design phase) Backend APIs will be provided by us. The contractor is only responsible for frontend integration and testing according to the API documentation. Web Version Requirements Functional flow consistent with the mobile apps No requirement to access device photos, contacts, or GPS Implemented using Flutter Web Technical Requirements Flutter must be used as the primary development framework A single codebase should output Web, Android, and iOS builds Deliverables must include: Android APK iOS IPA Project Milestones and Payment Structure Phase 1: UI/UX Design (Figma) Deliver complete Figma designs for Web and Mobile Include: User flow diagrams Form screens Permission and authorization explanation screens Payment for Phase 1 will be made after design review and formal approval. Phase 2: Technical Proof of Concept (POC) Develop a minimal test version (full features not required) to validate the following: Android and iOS apps can be installed and launched successfully Successful integration with our provided APIs Ability to retrieve and transmit: First five photos Contacts Location data Deliverables for this phase: Android APK iOS IPA Payment for Phase 2 will be made after all above items pass testing and acceptance. Phase 3: Full Feature Development Implement all system features based on the approved Figma designs Complete Web, Android, and iOS versions Bug fixes and basic testing Payment details for Phase 3 can be discussed separately. Contractor Qualifications Proven experience with Flutter (Web, Android, and iOS) Hands-on experience accessing the following device permissions: Photos / storage Contacts GPS location Ability to clearly explain Android and iOS permission handling and limitations Comfortable working with milestone-based delivery and acceptance

Hi jianyingc, We’ve developed multiple web and mobile apps using Flutter, including solutions that required extensive device permission handling. We understand the nuances of both Android and iOS permissions, and we can guide you on best practices to ensure a smooth user experience. For your project, we can also provide a dedicated backend developer to create robust APIs that ensure data security and integrity. We’ve built several products with similar workflows, so we know how to design effective user flows that lead to higher conversion rates. Let’s schedule a 10-minute call to discuss your project in more detail and see if I’m the right fit for your needs. Best, Adil

Hi there. Building a single Flutter codebase for a pawn loan application across Web, Android, and iOS while securely handling sensitive data like the first five photos, contacts, and GPS is highly complex—if device permission integration fails the Phase 2 PoC, your entire project timeline will collapse. I specialize in cross-platform development where secure, authorized access to device hardware is non-negotiable, ensuring your critical data collection requirements for risk assessment are met flawlessly on both Android and iOS from the very first test build. I will structure the permission handling and API integration logic specifically to pass your Technical Proof of Concept milestone and guarantee reliable data submission for backend review. Here are my questions: 1. Given the sensitivity of contacts and photos, what are the specific iOS and Android best-practice strings/explanations required in the permission authorization pop-ups for compliance? 2. Are you utilizing a standard REST API for the backend, and is the photo/file upload mechanism (e.g., base64 or multipart form data) already defined in the provided API documentation? Let’s discuss your project now!

HELLO, WE’VE CAREFULLY REVIEWED YOUR FULL PROJECT BRIEF AND TECHNICAL SCOPE, AND THIS IS A SYSTEM WE CAN CONFIDENTLY DELIVER. WE HAVE WORKED ON SIMILAR PROJECTS AND CAN PROVIDE EXAMPLES. We’ve read your requirements in detail and clearly understand the structure and intent of this pawn loan application system. This includes Flutter-based cross-platform delivery (Web, Android, iOS), strict permission handling for photos, contacts, and GPS, API-driven frontend integration, and milestone-based execution across design, POC, and full development. With 8+ years of hands-on experience building Flutter applications that handle sensitive device permissions and API-centric workflows, we’re comfortable explaining platform limitations, implementing consent-first data access, and delivering installable APK and IPA files strictly for internal testing and validation. WORKING FLOW Requirements Alignment & UX Planning → Confirm data fields, user flow, and permission logic before design begins. UI/UX Design in Figma → Create clear form screens, authorization explanations, and end-to-end user flows. Technical POC Build → Validate API connectivity, permission access, and successful APK/IPA installs. Full Flutter Development → Implement approved designs across Web, Android, and iOS from a single codebase. Testing & Delivery → Run functional testing, fix issues, and deliver final builds for acceptance. Invoke Tech

I’m glad to apply for this project, and with 6+ years of hands-on Flutter experience, I’ve built multiple cross-platform systems that handle device permissions, sensitive user data, and milestone-based delivery with strict acceptance criteria. I clearly understand the scope: Phase-wise execution starting from Figma UI/UX, followed by a technical POC validating photos, contacts, GPS access, and API connectivity, and then moving into full-feature development across Web, Android APK, and iOS IPA from a single Flutter codebase—with no backend responsibility on my side. I have practical experience handling Android & iOS permission flows, platform limitations, and user authorization screens, ensuring compliance and smooth testing in internal distribution environments. I’m comfortable working with structured milestones, clear reviews, and acceptance testing, and I can start immediately once APIs and requirements are shared. Let’s connect to align on timelines and begin Phase 1 without delay. Thanks & Regards Nikita Gupta
