# Utopia > Flutter-first software studio in Krakow, Poland. Ships production Flutter apps using AI agents, > on an architecture and skills layer the studio open-sourced. Founder-led: a co-founder reads > every inquiry and replies within 24 hours. Utopia (legal entity: Utopia Ultimate Software Solutions) is a founder-led Flutter studio. The founding team has been cooperating on Flutter since version 1.0, released December 2018. The studio builds new Flutter products end to end, rescues codebases in trouble (FlutterFlow and AI-generated apps, native iOS plus Android consolidations, Xamarin and .NET MAUI migrations), and ships AI features with production discipline. The architecture behind every build is published: utopia_hooks and its package family on pub.dev, plus Claude Code skills in the utopia-flutter-skills marketplace that teach AI agents to write this exact architecture.

We read the codebase first, in writing, then rebuild it as Flutter your team can own. - [Native iOS & Android to Flutter](https://utopiasoft.io/services/flutter-rescue): Maintaining two native apps with two teams? We port Swift and Kotlin into one Flutter codebase your whole team ships - incrementally, with both apps live. - [Xamarin & .NET MAUI to Flutter](https://utopiasoft.io/services/maui-rescue): Xamarin is past end of support, and .NET MAUI inherits the same dead end - we migrate to Flutter ahead of your deadline, while it keeps shipping. ## Open source - [utopia_hooks](https://utopiasoft.io/open-source/utopia-hooks): utopia_hooks: flexible Flutter state management inspired by React Hooks. Local, global, async, and form state in one model, decoupled from the widget tree. - [utopia_cms](https://utopiasoft.io/open-source/utopia-cms): utopia_cms: a Flutter-native admin-panel toolkit - sortable, filterable CRUD tables over Firebase, Supabase, Hasura, or any GraphQL backend. - [utopia-hooks](https://utopiasoft.io/open-source/skill-utopia-hooks): utopia-hooks: the Claude Code skill our agents use to write Flutter screens - Screen/State/View, the full hook catalog, and a quality gate after every edit. - [utopia-cms](https://utopiasoft.io/open-source/skill-utopia-cms): utopia-cms: the Claude Code skill our agents use for Flutter admin panels - declare fields, point a delegate, skip the hand-rolled DataTable. - [utopia-ai-arch](https://utopiasoft.io/open-source/skill-utopia-ai-arch): utopia-ai-arch: the Claude Code skill that builds our agent system itself - a four-agent roster, write boundaries, and enforcement hooks that block bad edits. - [utopia-hooks-migrate-bloc](https://utopiasoft.io/open-source/skill-utopia-hooks-migrate-bloc): utopia-hooks-migrate-bloc: the Claude Code skill that migrates a Flutter BLoC/Cubit codebase to utopia_hooks - a 5-agent pipeline behind a 7-point exit gate. - Full catalog: 23 packages under the verified publisher, listed at https://utopiasoft.io/open-source ## Case studies - [Jolly Phonics](https://utopiasoft.io/work/jolly-phonics): Jolly Learning teaches millions of children to read. For six years we've been their software side: two Flutter apps, a gRPC backend, a live CMS, and the commerce layer behind their distributor network. - [Moje Fizjo/Zdrowie+](https://utopiasoft.io/work/moje-zdrowie): Poland's National Health Fund needed two patient apps for its POZ Plus programme: chronic-disease care and physiotherapy. We shipped both from one Flutter codebase. - [Habicy](https://utopiasoft.io/work/habicy): Habit apps trust the checkbox. Habicy asks for a photo and posts it to a feed your friends actually watch - peer pressure, doing what streaks alone cannot. - [Black Phone](https://utopiasoft.io/work/black-phone): Quantum Bridge builds quantum-safe key distribution. Black Phone is where it ships: post-quantum encrypted chat and calls, plus the portal, the kiosk, and the backend - every one of them Dart. ## Company - [About Utopia](https://utopiasoft.io/about): the founder-led studio, its story, and the team. - [Contact](https://utopiasoft.io/contact): reach a co-founder directly; a reply within 24 hours. ## Verified facts - Open-source Dart/Flutter packages on pub.dev: 23, under the verified publisher utopiasoft.io (https://pub.dev/publishers/utopiasoft.io). - Tagged releases in the utopia-flutter monorepo: 797 as of July 2026 (https://github.com/Utopia-USS/utopia-flutter). - Flagship packages: utopia_hooks (state-management architecture for Flutter, BSD-2-Clause), utopia_cms (Flutter-native admin-panel toolkit, BSD-3-Clause). - Claude Code skills: 4 plugins in the utopia-flutter-skills marketplace: utopia-hooks, utopia-cms, utopia-ai-arch, utopia-hooks-migrate-bloc. - Architecture pattern: Screen · State · View is the pattern utopia_hooks implements - a Screen composes the hooks, a hook-based State holds the logic decoupled from the widget tree, and a View renders it (documented at https://hooks.utopiasoft.io). - Agentic Flutter development is the practice of having AI agents write production Flutter, running on a stack of skills (project conventions, published Flutter skills, and specialised ones for the hard parts) rather than off a blank prompt, with a senior Flutter engineer reviewing every change before it lands. - Founders: Jakub Walusiak, Jakob Kirchner, Thomas Kirchner, Pawel Adamarek. - Rating: 5.0 on Clutch (4 reviews). - Registered in Krakow, Poland.
