I need a production-ready Flutter / Dart code-base that mirrors the core experience of [login to view URL] while remaining clean enough for my team to extend after launch. All data—user accounts, weather, map layers, and our fishing forecaster—is already exposed through stable REST / JSON APIs, so the primary focus is the mobile presentation layer and tight Garmin SDK integration. Key functions to ship • Secure e-mail / social login tied to existing Lake-Link profiles • Garmin lake maps rendered with the official SDK, plus full offline caching so anglers can view chart data without coverage • Dynamic weather updates alongside additional map overlays we expose through our endpoints • Fishing Forecaster module showing predictive recommendations in a simple, swipeable interface fed by our live scores API Tech expectations • Flutter 3.x targeting iOS and Android from a single code base • State management with Provider, Riverpod, or Bloc—whichever you are fastest with and can document clearly • Null-safe, well-commented Dart, separated into data, domain, and UI layers • Build scripts for TestFlight / Play Console plus basic CI setup (GitHub Actions is fine) Schedule Alpha build with maps and login by mid-September, feature-complete beta by October, store-ready release before November ends. Frequent TestFlight drops and issue tracking in Jira or GitHub Projects will keep us on pace. Deliverables 1. Source repo with history 2. Compilable APK / IPA builds at each milestone 3. README covering environment setup, Garmin SDK steps, and API stubs 4. Short Loom or YouTube walkthrough of final build If you have shipped at least one Flutter app that handles offline maps or heavy GIS layers, let’s talk—I’m ready to start immediately and can supply API keys and the paid Garmin license on day one.

I would build this as a clean Flutter 3 app around the existing Lake-Link APIs, not as a generic content app. The first milestone would prove login/session handling, Garmin SDK lake-map rendering, and offline chart caching on both iOS and Android. My focus would be: - Dart layers separated into API/data, domain, and UI so your team can extend it later - Garmin map integration, offline cache rules, weather overlays, and weak-signal error states - Fishing Forecaster screens fed by your live score endpoints with clear loading/fallback behavior - Riverpod/Bloc/Provider state management with documented choices - TestFlight/Play builds, GitHub Actions basics, README/API stubs, and handover walkthrough I can start with an alpha slice for auth + maps + one API-fed forecast flow, then expand toward the beta/store milestones.

Hi there, I will build your Flutter fishing app with Garmin SDK map rendering, full offline caching for lake charts, and the swipeable Fishing Forecaster module, all wired to your existing REST/JSON endpoints. Since your APIs are stable, the real challenge is the offline map layer. I will structure the caching so anglers get reliable chart data in dead zones, with background sync when signal returns. On a recent Flutter app with heavy GIS overlays, this approach kept the tile load smooth even on older Android devices. I will follow a clean data/domain/UI layer split with Riverpod, so your team picks up the code base quickly after launch. Questions: 1) Which Garmin SDK version does your paid license cover, and do you have sample tile endpoints ready? Send me a message and we can go over the details. Best regards, Kamran

Hi! This is a solid, well-scoped project — the API-first approach and having the Garmin license ready on day one makes a big difference, it keeps the mobile work focused on what it should be. A few things worth clarifying before we lock scope: for the Garmin SDK integration, are you targeting Garmin ActiveCaptain / the lake map SDK specifically, or a different part of their ecosystem? And on offline caching — do you need full tile caching (download a region ahead of time) or just session-level persistence when coverage drops mid-trip? Those two questions probably have the biggest impact on the October beta timeline. We'd build this in Flutter 3.x with Riverpod for state (clean separation, good testability, easy to hand off) and structure the repo in data / domain / UI layers as you described. The CI with GitHub Actions, TestFlight drops, and milestone APK/IPA builds are all standard for us. The mid-September alpha for maps + login is tight but workable if API keys and the Garmin license land in the first week — happy to structure the first sprint around unblocking that dependency early. Let me know those details and we can get into the specifics of the milestone breakdown. Gustavo & the DoTheCode team

Hi, We’ve developed multiple apps with offline maps and heavy GIS layers, including a fishing app that integrates with Garmin and uses AI to suggest fishing spots based on historical data. We also built a web app for admins to manage users and create new fishing spots, which were then displayed in the mobile app. For your project, we can use the latest Flutter 3.10 version with Dart 3.0, and we’re equally proficient with both Provider and Riverpod for state management. We also have extensive experience with CI/CD pipelines and can set up GitHub Actions to automate builds and deploys. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit. Feel free to message me anytime—I usually respond within 10 minutes. I’m eager to learn more about your exciting project. Best regards, Adil

This sounds less like a simple Flutter clone and more like a field-ready fishing app where maps, weather, and forecasts still need to feel reliable when coverage drops. I’d start by wiring the existing auth and API layer cleanly, then build the Garmin map screen early since offline caching is the highest-risk part. After that I’d add weather and overlay rendering as separate data sources so your team can extend layers without touching the map core. For state management, I’d likely use Riverpod with a clear data/domain/UI split, keeping Garmin SDK calls isolated behind services. I’d also add retry handling, cache expiry rules, and graceful empty/offline states so anglers never hit a dead screen. One small improvement I’d suggest is preloading selected lake data before a trip. A couple of questions: are your offline lake regions predefined or user-selected? And do the social login providers already exist in your API? Ready to start.
