I need a lightweight Flutter application that lets visitors explore 40 outdoor artworks spread over roughly five kilometres. The core of the experience is a live GPS map (Google Maps SDK) showing the user’s position and the nearest artwork; a simple list view must automatically sort every piece by distance in real time. For each artwork the screen should present: • 2–3 hi-resolution images • A 3–4 minute audio interview which is stored in the database using backend • A short text blurb we’ll supply I will deliver all UI designs, colour palettes and assets. What I need from you is the complete build for both iOS and Android using Flutter, plus a small, browser-based backend (any lightweight stack you’re comfortable with) where my team can drag-and-drop new photos, type copy, and upload MP3 files without touching code. Key requirements • Native-like performance on iOS & Android Flutter? • Google Maps integration with blue-dot location tracking and walking directions • Menu list that re-orders by proximity automatically • Fast initial download size; keep heavy media optional or cached after first play • Clean, well-commented code so we can maintain content updates internally Acceptance criteria 1. Builds install and run error-free on current iOS and Android phones. 2. Distance-based ordering and map positioning are accurate to within typical GPS tolerances. 3. CMS lets a non-technical user add or edit an artwork entry in under five minutes. 4. Final hand-off includes source code, backend credentials, and setup documentation. If this sounds like a project you can deliver, tell me how you’d approach the Flutter architecture and the backend choice, plus an estimated development timeline. We will only consider delveipers whos has done work with this kind of apps and has years of experince and have more than 100 reviews here.
