Migration assessment
Before anything, we read the Xamarin or MAUI codebase and tell you, in writing, what carries over, what gets rebuilt, and what the move will take.

Xamarin & .NET MAUI to Flutter
Xamarin has reached end of support, and .NET MAUI inherited the same uncertain future - Microsoft's cross-platform path is a dead end. The ecosystem is thinning, the hiring pool is shrinking, and every month on it adds support and security exposure. We migrate the app to Flutter before the deadline forces a scramble - incrementally, while it keeps shipping, and you own the result.
why this exists
A closing stack is a slow emergency.
Nothing breaks the day support ends. The cost is quieter: fewer maintained libraries, harder hires, security patches that arrive late or not at all, and a migration that gets more expensive the longer it waits. The deadline does not wait for a good quarter.
And the move is not a sideways step off a dead end. Flutter compiles ahead of time to native code and draws its own UI with one rendering engine, so the app looks and performs the same on every platform instead of bending to the native controls each OS ships, the way Xamarin and MAUI do. You are not escaping to a safe option - you are upgrading to a better one.
We move the app to Flutter on utopia_hooks in Screen · State · View - the structure every app we ship stands on - mapping your C# and .NET patterns onto Dart and Flutter so the result is something your team reads, not reverse-engineers.

what we do
How we get you off the dead end.
// 02
C# / .NET to Dart / Flutter
We map the concepts you already rely on - bindings, view models, dependency injection - onto their Flutter equivalents, so the rebuilt app behaves the way yours does today.
// 03
Incremental migration
We rebuild behind the running app, screen by screen, so you keep shipping to users while the old stack is replaced - the app keeps shipping through the move.
// 04
Feature parity, then forward
We reach parity with what users have now before adding anything - same flows, same behaviour - then the roadmap you paused on the old stack becomes possible again.
// 05
Hand-over & enablement
When it ships, the code is yours: Flutter a .NET team can read from day one, with the C#-to-Dart context written down so nobody has to guess.
the migration, step by step
From assessment to hand-over.
- 01
Assess
We read the Xamarin or MAUI codebase and report, in writing, what carries over to Flutter, what has to be rebuilt, and what the move will take.
- 02
Plan
We agree the order of migration - which screens move first, what stays on the old stack longest - so the app keeps working for users the whole way through.
- 03
Migrate
We rebuild it in Flutter, mapping your C# and .NET patterns onto Dart, and you watch parity land screen by screen.
- 04
Reach parity
We match what users have today - every flow, every behaviour - before adding anything new, so the switch is invisible to them.
- 05
Hand over
The code is yours - readable, documented, maintainable. Your team takes it from here on a stack that will still be supported next year.
how we judge it
What carries over, in writing, before the clock runs out.
Before anything moves, we read the Xamarin or MAUI codebase and answer the migration's three hard questions: what carries over, what gets rebuilt, and how long the move takes against your support deadline. The assessment lands on your desk before any commitment does.
common questions
Questions we get asked.
Is it too late to migrate before Microsoft's support ends?
Only if you wait past the point where a migration can be planned and run before the deadline. The earlier we read the codebase, the more of the move happens on your schedule instead of a forced one - that is the first thing the migration assessment tells you.
Can Xamarin or MAUI just be patched instead of migrated?
You can delay, but the ecosystem keeps thinning under you either way - fewer maintained libraries, a shrinking hiring pool, security patches that arrive late or not at all. Patching buys time; it does not fix the underlying dead end.
How much of our C#/.NET logic carries over to Flutter?
It depends on the codebase, which is exactly what the migration assessment establishes in writing before anything moves - we map your bindings, view models, and dependency injection onto Flutter equivalents rather than starting from zero.
Can the migration happen while we keep shipping?
Yes - we migrate screen by screen behind the running app, so it keeps shipping to users through the whole move. There is no freeze and no all-or-nothing cutover.
Why move to Flutter instead of staying in the Microsoft ecosystem?
Because there is no longer a growing Microsoft cross-platform option to stay in - Xamarin has reached end of support and .NET MAUI inherited the same uncertain path. Flutter compiles ahead of time to native code with one rendering engine, so the app performs the same on every platform instead of bending to each OS's native controls.
