Your journey from idea to store-ready app
We start with a discovery session where we map the business goals, the audience and the constraints. We define the essential features together and separate "must have" from "nice to have". You can bring inspiration designs, competitor screenshots, or just an idea written on a napkin.
We create wireframes that show the structure clearly, then an interactive prototype you can touch before we write a line of Flutter code. The design respects your brand but also Material 3 and Cupertino — on Android it looks like Android, on iOS like iOS.
Implementation in Flutter with one codebase for iOS and Android (and optionally web and desktop). Modular architecture, clean state management (Provider/Riverpod/Bloc, depending on need), CI/CD on GitHub Actions or Codemagic. Weekly demo on TestFlight + Internal Testing.
Unit tests for logic, widget tests for UI, integration tests for critical flows. Manual testing on real devices (not just simulators) — iPhones four generations old, low-end Android, small and large screens. Crashlytics + analytics integrated from day 1.
Submission on the App Store and Google Play, with all metadata, screenshots and policies up to date. We handle Apple and Google review communications for any rejection. Technical documentation and training so your team can run the app.
Post-launch we collect user feedback and real telemetry to plan iterations. As you grow, we add advanced features — on-device AI, push notifications, in-app purchases, B2B integrations. Our apps stay future-proof.
On pub.dev
Building Flutter apps puts us in front of real problems. When the right package is missing, we write it, publish it on pub.dev under our verified tagonsoft.com publisher, and let the whole Flutter community use it.
Verified publisher: tagonsoft.comFlutter plugin for the PortSIP VoIP SDK
A Flutter wrapper around the PortSIP VoIP SDK — SIP calling, call controls (hold, mute, DTMF, loudspeaker), CallKit on iOS and ConnectionService on Android, SRTP encryption, OPUS/G.722/G.729 codecs.
· We built it for a client telephony app. No Flutter plugin existed for PortSIP, so we shipped one — and open-sourced it so nobody else has to start from scratch.
Dart SDK for the Groq AI API — blazing-fast LLM inference
A clean, idiomatic Groq API integration for Dart and Flutter. Multi-model support (Llama 3, Qwen, GPT-OSS), temperature/seed config, custom system instructions, chat session management, typed error handling.
· First used to add smart search across the product catalog in the WeReload app — the user types what they want in natural language, Groq returns matching results in under a second.
