What we build in Flutter

Five engagement shapes. This is what we actually ship, not a list of everything Flutter can theoretically do.

Greenfield Flutter apps

Discovery through App Store and Google Play launch, in Dart and Flutter, with a fixed scope set before anything is signed. One codebase, one team, both stores.
Offline-first architecture

Local-first writes that reconcile when the network returns, so the interface never waits on a round trip. This is the pattern we used on Wave, and it changes the whole architecture rather than just the storage layer.
Rescue and takeover

We assess a stalled Flutter codebase in seven days and tell you honestly whether to rescue it or rebuild it. Trying to do both on a tight budget rarely works, so we decide upfront.
Backend and APIs

The service layer your app talks to, sized for the deployment target rather than for habit. On Wave that meant dropping Express for Hono, because a lighter footprint means faster cold starts on Cloud Run.
Store launch and post-launch engineering

Submission at launch, then ongoing work on the roadmap. We do not disappear at the launch milestone, and OS-version migrations are part of the standing engagement rather than a surprise invoice.

The Flutter build

Wave, and the two calls we made against the obvious answer

Wave had to work with no signal at all. That single constraint decided the architecture, and it is why the app feels the way it does.

Tap

The user does something

Local write

PowerSync writes to the on-device database first

UI updates

Instantly, with no network involved

Reconcile

The backend catches up whenever it can

Everything above the reconcile step happens with the network switched off. Backend round-trip time never sits on the user critical path, so we stopped tuning for latency the user cannot feel.

Framework

Flutter over React Native

We had been exploring Flutter and the bet paid off in stronger runtime performance and shorter build times. The build-time win was not why we picked it, but it mattered for iteration speed.

Sync

PowerSync, local-first

Writes land locally and reconcile afterwards. Combined with Flutter's render performance, we stopped worrying about database latency entirely.

Backend

Hono on Cloud Run

We dropped Express because a lighter footprint means faster cold starts and lower memory, and on a serverless stack that compounds.

The honest part: development started long after an incomplete research phase, and a real share of the early effort went into re-aligning on what we were building. Product memory decays fast across a gap like that, which is why we now close discovery straight into build.

The honest version

Should you actually build in Flutter?

Pick the line that sounds most like your product. Three of these five answers are not Flutter, because on three of these five projects Flutter would be the wrong spend.

Both stores at once, one small team, a mostly visual product A field app that has to keep working with no signal Camera, on-device machine learning, or real-time AR Deep Apple surfaces: HealthKit, Live Activities, watchOS You already run a strong React and JavaScript team

Build it in Flutter

This is the case Flutter was built for

One team writes one Dart codebase and ships to both stores. Because Flutter draws its own widgets instead of mapping to platform components, the interface behaves the same on an iPhone and on a mid-range Android, which removes most of the per-platform QA that makes two native builds expensive.

You are trading a small amount of platform-native feel for roughly half the surface area to maintain. For a visual product with a small team, that trade is almost always correct.

Typical range for this shape of build is $25,000 to $60,000 over six to twelve weeks.

Build it in Flutter

Offline-first is where Flutter earns its keep

We built Wave this way. The app had to work fully offline, so writes go to a local database immediately and reconcile with the backend afterwards. Every interaction reads and writes locally first, so the interface stays instant no matter what the network is doing.

The part teams underestimate is that this changes the whole architecture, not just the storage layer. Backend round-trip time stops sitting on the user critical path, which means you stop tuning for latency you no longer feel.

Read the Wave build below for how the sync layer actually works.

Build it native

We have made this call against Flutter

On AcuHealth.Life we needed hand-tracked AR with on-device machine learning running at 60 frames per second. We went native Swift and Kotlin rather than Flutter or React Native, because the inference and the AR rendering both needed direct access to the platform camera pipeline and GPU surfaces.

Bridging that through a cross-platform layer would have added latency we could not afford on the overlay. If your product lives on the camera, Flutter is the wrong tool and we will say so on the first call.

The native path is here: iOS app development.

Build it native

Platform-deep features are a native job

HealthKit, Live Activities, watchOS companions, home-screen widgets and App Clips are all reachable from Flutter through platform channels, but every one of them means writing the native code anyway and then maintaining the bridge on top of it.

When the roadmap is mostly these surfaces, you are paying for a cross-platform layer you keep stepping around. Build native and skip the bridge.

The native path is here: iOS app development.

Look at React Native first

Your team is the deciding factor, not the framework

If you already employ strong React and JavaScript engineers, React Native lets them contribute on day one. Dart is a good language and it is quick to learn, but it is still a hiring cost, a ramp cost and a smaller local talent pool, and none of that shows up in a framework comparison chart.

We build in both. We picked Flutter on Wave against the obvious React Native default, and the bet paid off there. That does not make it the default for you.

We also build cross-platform in React Native: mobile app development.

When Flutter is the wrong call

On AcuHealth.Life we needed hand-tracked AR with on-device machine learning at 60 frames per second.

We built it native. The inference and the rendering both needed direct access to the camera pipeline and GPU surfaces, and a cross-platform bridge would have added latency we could not afford.

Camera frame +bridge ML inference +bridge AR render 16ms budget, 60 times a second

If your product lives on the camera, Flutter is the wrong tool and we will say so on the first call. The table below is where the rest of that argument lives.

AcuHealth.Life running a hand-tracked AR overlay, with acupressure points detected live on the user's palm — AcuHealth.Life. Points tracked on the hand in real time, which is the part a bridge would have slowed down.

Flutter, React Native, or native

The comparison as we actually run it in discovery. We build all three, so none of these rows is a sales position.

What you are weighing	Flutter	React Native	Native
Rendering	Draws its own widgets, so both platforms look identical	Maps to real platform components	Platform components by definition
Camera, on-device ML, AR	Possible, with a bridge in the way	Possible, with a bridge in the way	Direct access to the pipeline and GPU
Offline-first products	Strong, and proven on our own work	Workable with the right sync layer	Strong, at twice the surface area
Hiring and ramp	Dart is quick to learn, smaller talent pool	Any React engineer contributes on day one	Two separate skill sets to staff
Codebases to maintain	One	One	Two
Deep platform surfaces	Reachable through platform channels	Reachable through native modules	First-class, no bridge to maintain

What a Flutter build costs

Most Flutter builds with us land between $10,000 and $100,000-plus. What moves a project inside its band is rarely the screen count, it is the integration surface and the data model. We quote against your specification and we do not work hourly.

$10,000 - $25,000

Flutter MVP, one core flow

4 to 6 weeks

$25,000 - $60,000

Full app, both stores

6 to 12 weeks

$40,000 - $100,000

Transactional or commerce app

2 to 4 months

$65,000+

Offline-first or hardware-integrated

4 to 8 months

How the engagement runs

Five stages, and discovery closes straight into build. The gap between the two is where products lose their memory.

Discovery
Week 1
We run the Flutter versus React Native versus native decision with you, size the integration surface, and produce a fixed scope and a fixed price before a contract exists.
Architecture
Week 1 to 2
Data model, sync strategy and backend target chosen together. On an offline product this is the decision that shapes everything after it, which is why it does not wait until build.
Build
Two-week cycles
Dart and Flutter, with a product manager and full QA on the project rather than sold to you as an upgrade. You see working software at the end of every cycle.
Store launch
Launch week
Submission to the App Store and Google Play, with the listing treated as a launch deliverable rather than something marketing handles afterwards.
After launch
Ongoing
Roadmap execution and OS-version migrations under a standing engagement. The app does not stop needing engineers the day it ships.

Apps we have shipped

Work from across the practice. These span native and cross-platform rather than being a Flutter portfolio, because Wave above is our Flutter build and we would rather show you the real boundary than pad the list.

Flutter questions we get asked

How much does it cost to develop a Flutter app?

Most Flutter builds with AppMakers land between $10,000 and $100,000-plus, depending on how much the app has to integrate and how complex its data model is. A single-flow MVP runs $10,000 to $25,000 over four to six weeks. A full app shipping to both stores runs $25,000 to $60,000 over six to twelve weeks. We quote against your actual specification rather than a category average, and we do not work on hourly contracts.

Is Flutter still worth it in 2026?

For most products that need to ship on both stores with one team, yes. Flutter renders its own widgets rather than mapping to platform components, so the interface behaves the same on iOS and Android and you maintain one codebase. Where it stops being worth it is narrower than people assume. If your product depends on camera pipelines, on-device machine learning, real-time AR, or deep platform surfaces like Live Activities and watchOS, native is usually the better spend. We will tell you which case you are in before you commit.

Is Flutter still owned by Google?

Flutter is an open-source project created and maintained by Google, released under a BSD licence, with a public repository and outside contributors. Google steers the roadmap and ships the releases. For a buyer the practical question is not ownership but continuity, and the honest answer is that Flutter has a large installed base of shipped apps and an active contributor community, which is what keeps a framework maintainable.

Should we choose Flutter or React Native?

It depends on your team more than on the frameworks. If you already run a strong React and JavaScript team, React Native lets them contribute on day one and Dart becomes a hiring and ramp cost you do not need. If you are starting fresh, or your product is visually dense, Flutter usually gives more consistent rendering across both platforms. On Wave we chose Flutter over React Native deliberately and the bet paid off in runtime performance and build times.

Can you take over an existing Flutter project?

Yes. Rescue and takeover is a core service line. We assess the existing codebase in the first seven days and tell you honestly whether to rescue or rebuild, then execute that path. Trying to both fix and rebuild on a tight budget rarely works, so we decide which one upfront.

Do you build offline-capable Flutter apps?

Yes, and it is one of the strongest reasons to pick Flutter. On Wave the app had to work fully offline, so we used PowerSync, which writes to the local database immediately and reconciles with the backend afterwards. Because every interaction reads and writes locally first, the interface stays instant regardless of network state, and backend round-trip time never sits on the user critical path.
