Flutter vs React Native: Why We Chose Flutter

The comparison nobody writes honestly

Most Flutter-versus-React-Native articles are written by someone who has shipped in one of them. We have shipped eight products on Flutter — five games, two apps, one platform — so treat this as a biased source that is at least trying to show its work, including the parts that argue against us.

The decision came down to four things, and we would make it again for most projects. Not all of them.

Rendering: the reason the decision is not close

Flutter draws every pixel itself through its own engine — Impeller on modern iOS and Android. React Native maps your components onto the platform's native widgets and coordinates across a boundary.

That architectural difference decides what is easy. In Flutter, a screen with parallax, drag-and-drop, particle effects and a synchronised soundtrack runs the same on both platforms because nothing is being translated. In React Native it can be made to work and often is — but the effort curve is steeper the further you get from standard components, and the two platforms drift apart as you go.

For our puzzle games this was decisive. For a form-and-list business app it matters far less, and anyone telling you otherwise is selling something.

Dart: dull in the best way

Dart is not an exciting language, which turns out to be the point. It is strictly typed with sound null safety, and it compiles ahead of time to native ARM. In practice:

• Mistakes surface at compile time instead of as a crash report from a user.
• Performance is predictable — no JavaScript engine pauses, no bridge serialisation to reason about.
• One language covers iOS, Android, web and desktop, so a fix is written once.

The cost is that Dart is used almost nowhere else. A JavaScript team can be productive in React Native next week; the same team needs a real ramp-up for Dart.

Ecosystem: smaller, and better maintained

npm is larger. That is not the same as better served. Flutter's core libraries are mature and actively maintained, and the standard set is small enough that most teams converge on it — which means the answer you find on a forum usually applies to your setup.

For our applications, we use:

• Bloc with get_it and freezed — predictable state and generated, immutable models. Riverpod where the graph is smaller and the ceremony is not worth it; Qivvo runs on it.
• Drift and Hive — typed local databases that work offline and encrypt at rest.
• go_router — declarative navigation that survives deep links and cold starts.

The gap shows up at the edges: a niche native SDK is more likely to have an official React Native wrapper than a Flutter one, and you end up writing a platform channel yourself.

Hiring, which nobody costs properly

There are more React Native developers than Flutter developers, and that is a real argument. It is also less decisive than it sounds, because the alternative most companies are actually comparing against is two native teams — and one Flutter team is cheaper and more coherent than that by a wide margin.

Where we would not choose Flutter

• A heavily platform-native product. Deep hardware access, complex background work, widgets and watch apps. Most of the code stays native; Flutter adds a bridge rather than removing one.
• An existing React Native team and codebase. Framework quality rarely beats institutional knowledge. Migration has to be justified by pain, not preference — and it usually is not.
• One platform that dominates. If 95% of revenue is iOS, cross-platform costs you native ergonomics and buys little.
• A tiny, short-lived app. For something that will exist for one campaign, whatever your team already knows wins.

The summary we actually believe

Flutter wins when you need one team, both platforms, and control over every pixel. React Native wins when you have a JavaScript organisation and a conventional interface. Native wins when the platform *is* the product.

We picked Flutter because our own products are visual, cross-platform, and built by one small team. That is a description of our situation, not a universal ranking — and any studio that gives you the same answer before hearing your situation is describing their staffing, not your project.
