Flutter vs React Native: A Malaysian Developer's Honest Comparison

Flutter vs React Native is the most common framework question we hear from CTOs and founders walking into our office in Kuala Lumpur. Both frameworks let you build iOS and Android apps from a single codebase, both have large communities, and both are backed by tech giants. But after shipping 150+ projects since 2012 — including Perodua, MyJPJ, SolarooEV, and Zlock — Advisory Apps uses Flutter as our primary mobile framework. This post explains why, where React Native still wins, and how to make the right call for your project.

The Short Answer

If you want a single framework recommendation for a new cross-platform mobile project in Malaysia in 2024, Flutter is our pick. It gives you tighter control over rendering, faster iteration on UI-heavy screens, and a type-safe language that catches bugs before they reach production. React Native remains a strong choice if your team already lives in JavaScript and you need deep integration with an existing web codebase. Neither framework is wrong — they solve the same problem with different trade-offs.

Head-to-Head Comparison

This table covers the dimensions that actually matter when choosing a framework for a production mobile app.

Both frameworks are production-ready and widely used. The differences show up in the details — and those details matter more than most comparison articles admit.

Why Advisory Apps Chose Flutter

We evaluated both frameworks seriously in 2019 and went all-in on Flutter for new mobile projects. Five years and dozens of production apps later, here is what validated that decision.

Rendering control matters for client work

Flutter does not use native platform widgets. It draws every pixel on its own canvas using the Impeller rendering engine (which replaced Skia as the default). This means a button, a list, a chart, or a custom animation looks identical on a Samsung Galaxy A14 and an iPhone 15 Pro. For an agency delivering to clients who compare screenshots across devices during UAT, this eliminates an entire category of bugs and revision rounds.

React Native renders through the platform’s native components, which means your UI inherits platform-specific styling and behaviour. That is an advantage if you want your app to feel “native” on each platform — but it is a disadvantage if your client’s design team hands you a pixel-perfect Figma file and expects it reproduced exactly.

Dart is a better language for team-scale development

This is subjective, but our experience is consistent. Dart 3.x with null safety, records, patterns, and sealed classes catches entire categories of bugs at compile time that JavaScript surfaces at runtime. When you have multiple developers working on the same codebase across sprints, the type system pays for itself in reduced debugging time.

TypeScript closes much of this gap for React Native projects, and we respect teams that use it well. But Dart was designed for UI development from the ground up — the async model, the widget composition pattern, and the build system all fit together without the friction of bolting type safety onto a dynamic language.

Performance is measurably better for UI-heavy apps

Flutter compiles to native ARM code via AOT compilation. React Native runs JavaScript through the Hermes engine and communicates with native modules via a bridge — though the New Architecture with JSI significantly reduces that overhead. For most CRUD apps, the difference is invisible. For apps with complex animations, large scrolling lists, real-time data, or custom rendering (charts, maps, AR overlays), Flutter’s architecture gives you more headroom before you hit performance walls.

Our SolarooEV project — an IoT app that streams live telemetry from electric vehicle hardware — is a case where that headroom mattered. We needed smooth 60fps chart rendering while processing Bluetooth data in the background. Flutter handled it without dropping frames.

One codebase, more platforms

Flutter’s web, macOS, Windows, and Linux targets ship from the same codebase. We have used this to deliver admin dashboards alongside mobile apps without maintaining a separate web project. React Native Web exists, but it is less mature — and desktop support relies on third-party community projects like react-native-windows and react-native-macos rather than first-party tooling.

Where React Native Still Wins

An honest comparison means acknowledging where the other framework has real advantages. Here is where React Native is genuinely stronger.

Talent availability

JavaScript is the most widely used programming language in the world. Any front-end developer with React experience can contribute to a React Native project on day one. Dart is a smaller ecosystem — finding experienced Flutter developers in Malaysia takes more effort, and hiring juniors means investing in Dart training. If your in-house team already writes JavaScript and you need them to own the codebase long-term, React Native reduces your hiring risk.

JavaScript and npm ecosystem

React Native has access to the entire npm registry — over 1.5 million packages covering everything from date parsing to Stripe integration to PDF generation. Flutter’s pub.dev has around 40,000 packages with a quality scoring system that filters out abandonware, but the total surface area is smaller. If your app depends on a niche third-party SDK that only provides a JavaScript wrapper, React Native integrates it without writing bridging code.

Brownfield integration

If you have an existing native iOS or Android app and want to add cross-platform features incrementally, React Native’s architecture makes brownfield integration more straightforward. Flutter can be embedded into existing apps too, but the process involves more configuration and the community tooling around it is less battle-tested.

Platform-native look and feel

Some apps — particularly enterprise tools used alongside native system apps — benefit from looking exactly like the platform they run on. React Native’s use of native components gives you this for free. Flutter requires you to build platform-aware UI manually if you want Material on Android and Cupertino on iOS, which adds development time.

What We Have Built With Flutter in Malaysia

Theory matters less than production results. Here are four projects we shipped with Flutter that demonstrate different use cases.

• Perodua — Malaysia’s largest automotive manufacturer by volume. Flutter delivered a consumer-facing app serving millions of users with dealership locators, service booking, and vehicle management features.
• MyJPJ — A government-adjacent application for vehicle and driving licence services. Required high reliability, offline capability, and accessibility compliance.
• SolarooEV — An IoT companion app for electric vehicle hardware. Real-time telemetry streaming over Bluetooth, live charts, and background data sync. This project stress-tested Flutter’s performance ceiling.
• Zlock — A smart lock management system combining BLE hardware communication, user permission hierarchies, and real-time access logs. Security-critical with zero tolerance for UI lag during lock/unlock operations.

Each of these projects had different requirements — consumer scale, government compliance, IoT performance, hardware integration — and Flutter handled all of them without framework-level compromises. You can see more of our delivered work in our portfolio.

How to Decide for Your Project

Framework choice should follow project requirements, not hype. Here is a decision framework based on what we have seen across 150+ projects.

Choose Flutter if:

• Your design team delivers pixel-perfect Figma files and expects exact reproduction
• Your app involves complex animations, charts, or custom rendering
• You want to ship mobile, web, and desktop from one codebase
• You are building a new project without legacy JavaScript constraints
• Performance headroom matters (IoT, real-time data, media-heavy apps)

Choose React Native if:

• Your team already writes JavaScript/TypeScript and will own the codebase
• You are adding cross-platform features to an existing native app
• Your app depends on npm packages without Dart equivalents
• Platform-native look and feel is a hard requirement
• Hiring JavaScript developers is easier for your organisation than hiring Dart developers

Either framework works if:

• You are building a standard CRUD app (forms, lists, API calls, authentication)
• Your timeline is four to six months
• You have a competent development team or agency regardless of framework

The wrong framework with a great team will outperform the right framework with a mediocre team every time. Framework choice matters, but team capability matters more.

The Malaysian Market Context

Malaysia’s mobile app market has specific characteristics that influenced our framework choice. The device landscape is heavily Android-skewed, with Samsung, Xiaomi, Vivo, and OPPO dominating the mid-range segment. These devices vary widely in GPU capability, RAM, and screen density. Flutter’s own rendering engine handles this fragmentation better than React Native’s reliance on native components, which can behave inconsistently across OEM Android skins.

Malaysian businesses also tend to scope projects that combine mobile apps with web dashboards for admin and operations teams. Flutter’s multi-platform output from a single codebase fits this pattern well — we can deliver a consumer mobile app and an internal web dashboard without doubling the engineering effort.

Talk to a Team That Ships Both

Advisory Apps has been building mobile applications from Kuala Lumpur since 2012. We chose Flutter as our primary framework because it consistently delivers better outcomes for the projects Malaysian businesses bring to us — but we evaluate every project on its own terms. If React Native is genuinely the better fit for your situation, we will tell you that in the first call.
