WHO WE ARE

A senior Flutter team you can outsource to

FusionHit is where US teams outsource Flutter without the cost and lead time of hiring in-house. Senior nearshore engineers, fluent in Dart, Flutter, and the native Swift and Kotlin layer underneath, work in your time zone as an extension of your team.

\
WHAT WE DO

Flutter services we provide

One senior team across the full Flutter lifecycle, from a new build to a version rescue.

Custom Flutter app development

iOS and Android from one codebase, with the platform differences handled rather than ignored.

Flutter and Dart version upgrades

Apps stranded on old releases brought current, replacing abandoned pub.dev packages as we go.

Add-to-app integration

Flutter modules embedded into an existing native app, screen by screen.

Native platform channels and FFI

Swift and Kotlin written where Flutter cannot reach: Bluetooth, background location, payments.

Performance optimization

Jank, rebuild storms, and binary size, profiled and reduced against real device targets.

Web and desktop expansion

The same Dart codebase extended past mobile when the numbers actually support it.

The team has been able to stay as a team for two years now. A single team, with nobody leaving. I've had a really stable team that I've seen grow in strength.

FAQ

FAQs about our Flutter development services

01

Why outsource Flutter development instead of hiring in-house?
One Flutter team replaces two native squads, and LATAM has unusually deep Flutter benches on US hours. You get that seniority in days at 30-50% below domestic rates. If you would rather bring talent onto your own payroll, see hire Flutter developers.
02

How much does Flutter app development cost?
It depends on scope, seniority, and engagement model (staff augmentation, a dedicated team, or full project outsourcing). Senior LATAM rates run 30-50% under US equivalents, with a line-item estimate on the first call and no hidden overhead.
03

Flutter or React Native for our app?
Flutter when the UI is custom and consistency across platforms matters most. React Native when you already have a React web team who should be contributing. We answer against your team, not a benchmark.
04

Will a Flutter app actually feel native?
For most product categories, yes. Users notice inconsistent behavior, not the rendering engine. Where a platform convention matters, we implement it per platform rather than pretending one layout fits both.
05

What happens when we need something Flutter does not cover?
We write the Swift and Kotlin ourselves through platform channels, FFI, or Pigeon. A Flutter team that cannot drop into native code is a liability, not a saving.
06

Our Flutter app is stuck on an old version with dead packages. Can you fix it?
Yes. The upgrade path gets reconstructed release by release, with abandoned dependencies replaced one at a time, rather than attempted as a single jump that nobody can review.
07

How much bigger will our app download be than a native build?
Measurably bigger, and how much depends on your assets and dependencies. We treat binary size as a tracked number when your market or MDM distribution makes it matter.
08

Can we reuse the codebase for web or desktop?
Sometimes, and the honest answer depends on the product. We size it before you commit, rather than selling the possibility as a plan.
