Hello! A cross-platform smart lock app with secure remote control and UWB support is a great fit for Flutter when it’s architected carefully around hardware communication and platform-level security. Here’s how I’d approach the build. Core Lock Control • Secure remote lock/unlock using encrypted API + device authentication • Real-time lock status sync with clear visual feedback • Fallback and retry handling for unreliable connectivity Access Logs & Notifications • Timestamped activity history (who accessed, how, and when) • Push notifications for lock/unlock events and failed attempts • Filterable logs stored securely and synced with backend Guest Access Management • Time-limited or recurring digital keys • Role-based access (owner, family, guest) • Easy revoke and audit trail of shared access UWB Integration • Native UWB modules bridged into Flutter via platform channels • Precise proximity detection for passive unlock scenarios • Secure distance bounding to prevent relay attacks Technical Foundation • Flutter with clean state management (Bloc/Riverpod) • Native iOS (Swift) + Android (Kotlin) layers for UWB and BLE • End-to-end encryption and secure key storage (Keychain/Keystore) • Scalable backend for device pairing, permissions, and logs Let’s discuss your lock hardware specs and communication protocol so we align the architecture from day one. Best regards, Jasmin

Hi there, I’ve read your Flutter Smart Lock App brief and I’m confident I can deliver a secure cross‑platform app for iOS and Android that enables remote locking, access logs, guest management, and UWB support. I’ve built Flutter apps for IoT/security with remote control, push notifications, and encrypted API calls. My approach: a secure architecture with a Flutter frontend, a backend API, and a device bridge for UWB/BLE; strong authentication, encrypted messages, and robust audit trails. Core features include remote lock/unlock, real-time notifications, guest access with time-bound passes, detailed access logs, and a reliable UWB pairing flow with graceful fallbacks to BLE when needed. I’ll ensure privacy, data protection, and smooth UX, with careful testing and security hardening. Timeline: discovery and scope in 1 week, MVP in 6-8 weeks, full feature set in 10-12 weeks. I can share references to similar Flutter IoT projects and secure mobile apps. Next steps: confirm scope and hardware/backend requirements, then I’ll deliver a sprint plan with milestones and a fixed quote. Could you share the exact lock hardware model and backend API specs, plus any existing authentication/tenant structure so I can align security and UWB implementation from day one? Best regards,

Hi, This is Elias from Miami. I checked your requirements and I understand you need a Flutter app for iOS + Android that controls smart locks remotely, tracks access events, manages guest keys, and supports UWB for a “walk-up / proximity” style unlock — with security and reliability being the priority. I’ve built secure mobile apps with device integrations, background events, and permission-heavy flows, and I’m comfortable designing this in a way that stays stable across both platforms (Flutter UI + platform channels for UWB / native capabilities where needed). Q1: Which lock hardware / SDK are we integrating (brand + model), and do you already have the UWB + cloud API docs? Q2: For guest access, do you want schedules (start/end time), one-time codes, or proximity-based sharing? Q3: Should the app work when the phone is locked / in background for UWB unlock, and do you want offline unlock fallback? Similar work examples I can share in chat (private demos/screens + walkthrough) since many lock/IoT projects are under NDA, but I can show live builds and architecture patterns. Regards, Elias
