Flutter Developer for Feed Bin Tracking App (Simple Prototype)

---

---

We are a family-owned hog farm looking to develop a simple mobile app prototype using Flutter to track feed bin levels and mortalities. The app will be tested on our farm initially, with potential for future expansion. We need a skilled Flutter developer to build a functional version with a specific interface design (see details below) and a basic web dashboard. Most of our team uses iPhones, so iOS support is required. Different sites have different bin sizes, and the app must allow users to choose the appropriate bin capacity. The home screen will list sites for selection, with administrators having the ability to edit or add new sites, including the number of bins and bin sizes, which remain static unless changed by the admin. Mobile App (Employee View): • Home Screen: A list of existing sites (e.g., custom names) for employees to select when reporting feed levels and mortalities. • Reporting Screen: o Single screen after site selection with a simple animated conical bin shape (based on a feed bin design, adjustable for different capacities, e.g., 15-ton default per site configuration). o 3 drag points (red dots) to adjust the feed level interactively, with a yellow shaded area indicating the feed level. o Real-time calculation of feed tons (e.g., 1.5T) and remaining capacity (e.g., 13.5T) based on the site’s configured bin size. o Text display: Bin Name (e.g., Bin #1), selected Capacity (e.g., 15T), and calculations (e.g., "Empty Space: 1.5T, Remaining Feed: 13.5T"). o Dropdowns for Line (e.g., Line 1) specific to the selected site. o Date field (auto-filled) and optional Notes text box. o Mortality Tracking: Below the bin, a dropdown menu for mortality types (e.g., chronic illness, respiratory, flu) and a text box to enter the number of mortalities (e.g., "1" for 1 pig). o Green "Submit" button. • Support for iOS (primary) and Android (secondary). Mobile App (Administrator View): • Home Screen: Same list of sites as employees, plus an "Admin" button or option. • Admin Screen: o Option to edit existing sites (e.g., update Barn Name, number of bins, bin sizes like 10T, 15T, 20T). o Option to add new sites with configurable number of bins and bin sizes. o Changes to bin sizes and numbers remain static unless updated by the admin. o Simple form with save functionality, syncing to Firebase. • Admin access restricted (e.g., password or role-based login). Web Dashboard (Farm Owner View): • Basic table listing submissions (Barn Name, Line, Date, Feed Tons, Remaining Tons, Status, Mortality Details) with thumbnails of the bin graphic, reflecting the site’s configured bin size. • Clickable details to view the adjusted bin shape, notes, mortality type, number of deaths, and status. • Status toggle (Pending/Ordered). • Admin option to edit site configurations (same as mobile admin screen). Technical Details: • Use Firebase for real-time data syncing between mobile and web. • Target iOS primarily (delivered as .ipa file), with Android (.apk) as a secondary option. • Simple, functional design based on the attached reference image (conical bin with 3 drag points). • Implement a site setup feature to assign different bin sizes (e.g., 10T, 15T, 20T) and number of bins per site, editable only by admins. • Store site configurations, bin data, and mortality data in Firebase. Deliverables: • Working mobile app (iOS .ipa and Android .apk) with employee and admin modes. • Web dashboard. • Source code with comments. • Basic testing and bug fixes on iOS. Timeline • Estimated 70-100 hours over 3-4 weeks. • Milestones: o 25% upfront upon contract signing. o 50% after mobile app completion (iOS focus). o 25% after web dashboard and final testing. Budget • $3,500 - $5,000 total, negotiable based on experience and timeline. • Prefer fixed-price, but open to hourly (max $50/hour). How to Apply • Submit a proposal with: o Brief overview of your Flutter experience. o Link to portfolio (e.g., GitHub, app demos). o Estimated timeline and cost within the budget. o Any questions or suggestions for the project. • Attach or reference the provided image for design inspiration. Notes • This is a prototype for internal testing. Future phases may include additional features (e.g., feed mill integration, Spanish language support). • Ownership and Confidentiality: The client will own all intellectual property rights to the deliverables upon full payment. The freelancer agrees to transfer all rights and keep project details confidential, with no reuse or disclosure without prior written consent. A formal contract with these terms will be required before starting.
