It&#8217;s about how each one loads code at runtime. React Native executes JavaScript, so with\u00a0Module Federation\u00a0(via Re.Pack) it supports genuinely independent, runtime-composed mini-apps and\u00a0over-the-air\u00a0JS updates. Flutter compiles Dart to native machine code ahead of time, so it can&#8217;t load new feature code after release, especially on iOS. Its modularity is build-time: packages, add-to-app, and Android-only\u00a0deferred components. Pick React Native for super-app and independent-squad architectures. Pick Flutter for rendering consistency and animation-heavy UIs shipped as a single binary.<\/p><\/blockquote>\n<h2><span class=\"ez-toc-section\" id=\"Micro-frontends-on-mobile-arent-micro-frontends-on-the-web\"><\/span>Micro-frontends on mobile aren&#8217;t micro-frontends on the web<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Most &#8220;micro-frontend on mobile&#8221; advice quietly assumes the web model still holds. It doesn&#8217;t. On the web, a host page stitches together independently deployed bundles served from different origins, and the browser executes whatever JavaScript arrives. There&#8217;s no gatekeeper between your remote bundle and the user.<\/p>\n<p>Mobile has two gatekeepers the web doesn&#8217;t: the\u00a0App Store review process\u00a0and the\u00a0native runtime. Apple and Google decide what ships, and both platforms draw a hard line around executable code. That single fact reshapes every architecture decision that follows.<\/p>\n<p>So when an enterprise asks for &#8220;micro-frontends&#8221; on mobile, what they usually want is one of three things: independent feature teams that can deploy without blocking each other, a super-app shell that loads mini-apps (often built by external partners), or an update cadence that doesn&#8217;t wait on a 48-hour store review. Each goal has a different answer depending on the framework. Which one are you actually solving for?<\/p>\n<p>The honest framing is this.\u00a0React Native can compose code at runtime because it interprets JavaScript. Flutter cannot, because it runs ahead-of-time compiled machine code.\u00a0Everything else in this comparison is downstream of that line.<\/p>\n<p>Also Read- <a href=\"https:\/\/dianapps.com\/blog\/flutter-vs-native-when-cross-platform-makes-sense\/\">Flutter vs Native: When Cross-Platform Actually Makes Sense?<\/a><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How-React-Native-composes-features-at-runtime\"><\/span>How React Native composes features at runtime?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>React Native is the only one of the two that supports a web-style micro-frontend pattern in production, and that capability rests on two pillars: the New Architecture and Module Federation.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The-New-Architecture-Why-removing-the-bridge-matters\"><\/span>The New Architecture: Why removing the bridge matters?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>React Native&#8217;s\u00a0New Architecture\u00a0has been the default since version 0.76, and from 0.78 onward the legacy bridge is gone entirely from new projects (React Native docs). This isn&#8217;t a cosmetic version bump. The old bridge serialized every JS-to-native call into JSON and shipped it across an asynchronous boundary, which is where the infamous bridge congestion and animation stutter came from.<\/p>\n<p>The replacement is\u00a0JSI\u00a0(JavaScript Interface), which lets JavaScript call native code synchronously without serialization.\u00a0Fabric, the new C++ renderer, brings concurrent rendering and React 18 features.\u00a0TurboModules\u00a0load native modules lazily and generate type-safe bindings at compile time through Codegen (Re.Pack \/ Callstack).<\/p>\n<p>Why does this matter for micro-frontends specifically? Because when you compose multiple independently built mini-apps into one shell, those mini-apps share state, call native capabilities, and cross thread boundaries constantly. On the old bridge, that cross-module chatter was a latency tax. With JSI and a bridgeless runtime, federated modules talk to native code with far less overhead, which is the difference between a super-app that feels native and one that feels like a wrapper.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Module-Federation-with-RePack\"><\/span>Module Federation with Re.Pack<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>True runtime composition in React Native runs on\u00a0Module Federation, delivered through\u00a0Re.Pack, Callstack&#8217;s Webpack and Rspack-based bundler that replaces Metro for this use case. The pattern is microservices for the frontend: a host app and independently built remote mini-apps that fetch each other&#8217;s code at runtime, with shared dependencies like\u00a0<code>react<\/code>\u00a0and\u00a0<code>react-native<\/code>\u00a0loaded once as singletons.<\/p>\n<p>Here&#8217;s the part teams underestimate. Mobile Module Federation is more constrained than its web cousin, and the constraints come straight from the platform. Per Re.Pack&#8217;s own documentation, every micro-frontend must use the\u00a0same React, React Native, and native dependency versions,\u00a0all native modules must live in the host app\u00a0that&#8217;s submitted to the stores, and you can only dynamically load\u00a0JavaScript\u00a0from a remote, not native code (Re.Pack).<\/p>\n<p>Read that again, because it&#8217;s the rule that breaks naive designs. A remote mini-app can reference a native module, but that module has to be compiled into the host binary first. Your &#8220;independently deployed&#8221; feature isn&#8217;t fully independent. It&#8217;s independent at the JavaScript layer and tightly coupled at the native layer.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Over-the-air-updates-React-Natives-real-advantage\"><\/span>Over-the-air updates: React Native&#8217;s real advantage<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>This is where React Native genuinely wins, and it&#8217;s often the actual reason enterprises reach for it. Because the framework executes JavaScript, you can push\u00a0over-the-air\u00a0updates to JS and assets without a store submission, using tooling like EAS Update. A payments squad can ship a fix at 2pm without waiting on the rest of the app.<\/p>\n<p>The limit is policy, not technology. Apple permits downloaded interpreted code as long as it doesn&#8217;t change the app&#8217;s primary purpose. Use OTA to fix bugs, tune flows, and run experiments. Don&#8217;t use it to remote-control core behavior, or you&#8217;re inviting a review problem. More on that landmine below.<\/p>\n<p>Suggested Read- <a href=\"https:\/\/dianapps.com\/blog\/choose-between-native-and-cross-platform-app-development\/\">How do I choose between native and cross-platform app development?<\/a><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How-Flutter-handles-modularity-powerful-but-build-time\"><\/span>How Flutter handles modularity: powerful, but build-time?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Flutter&#8217;s modularity story is real and mature. It&#8217;s just a different kind of modularity, and conflating it with runtime micro-frontends is how architecture reviews go wrong.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Impeller-AOT-and-the-single-binary-model\"><\/span>Impeller, AOT, and the single-binary model<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Flutter compiles Dart\u00a0ahead of time\u00a0to native machine code, and it draws every pixel itself through\u00a0Impeller, the default rendering engine since Flutter 3.27 on iOS and Android API 29 and above (Flutter docs). Impeller precompiles its shaders at build time, which kills the first-run animation jank that plagued the old Skia pipeline and supports 120Hz displays cleanly.<\/p>\n<p>The payoff is pixel-identical rendering across platforms and excellent animation performance. The cost, for our purposes, is rigidity. AOT machine code is fixed at build time. There&#8217;s no interpreter sitting in the runtime waiting to execute code you send later.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Deferred-components-and-the-Android-only-reality\"><\/span>Deferred components and the Android-only reality<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Flutter does support code splitting through\u00a0deferred components, using Dart&#8217;s\u00a0<code>deferred as<\/code>\u00a0imports and\u00a0<code>loadLibrary()<\/code>\u00a0to load feature modules on demand. On Android this hooks into Play Feature Delivery, so your base app stays lean and heavy features download when a user opens them.<\/p>\n<p>The catch is twofold and decisive. First, deferred components are\u00a0Android-only\u00a0(Flutter docs). Second, even on Android, they only split apart code that already existed when the binary was built. The Dart API documentation is explicit that you can&#8217;t ship feature code created after the app was distributed (Dart API). You still build and upload the entire app as a single Android App Bundle. There is no code push.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The-iOS-constraint-that-decides-the-architecture\"><\/span>The iOS constraint that decides the architecture<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>On iOS and macOS, Flutter offers\u00a0no code splitting at all. You can defer assets using Apple&#8217;s On-Demand Resources, but executable code isn&#8217;t part of that mechanism. Combining add-to-app with deferred components in one project isn&#8217;t officially supported either, and the Flutter team flags full Flutter deferral as an experimental, advanced setup without guarantees.<\/p>\n<p>So if your &#8220;micro-frontend&#8221; requirement includes delivering or updating feature\u00a0<em>code<\/em>\u00a0at runtime on iOS, Flutter can&#8217;t do it. Not because of a missing feature, but because Apple forbids downloaded executable native code and Flutter&#8217;s output\u00a0<em>is<\/em>\u00a0native code. That&#8217;s the whole ballgame for a lot of enterprise decisions.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Architecture-comparison-Flutter-vs-React-Native-for-micro-frontends\"><\/span>Architecture comparison: Flutter vs. React Native for micro-frontends<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The table below maps the two frameworks across the dimensions that actually drive enterprise architecture, not the ones that win Twitter arguments.<\/p>\n<div style=\"overflow-x: auto; margin: 1.5em 0;\">\n<table style=\"width: 100%; border-collapse: collapse; font-size: 15px; line-height: 1.5;\">\n<thead>\n<tr>\n<th style=\"border: 1px solid #d1d5db; padding: 10px 12px; text-align: left; background: #1f2937; color: #ffffff;\">Dimension<\/th>\n<th style=\"border: 1px solid #d1d5db; padding: 10px 12px; text-align: left; background: #1f2937; color: #ffffff;\">React Native (New Architecture + Re.Pack)<\/th>\n<th style=\"border: 1px solid #d1d5db; padding: 10px 12px; text-align: left; background: #1f2937; color: #ffffff;\">Flutter (Impeller + AOT)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"border: 1px solid #d1d5db; padding: 10px 12px;\"><strong>Runtime code loading<\/strong><\/td>\n<td style=\"border: 1px solid #d1d5db; padding: 10px 12px;\">Yes.

Third-party benchmarks tend to give Flutter a modest edge on cold launch and memory footprint thanks to AOT, while React Native&#8217;s New Architecture has narrowed the gap considerably (Bolder Apps).

Bump\u00a0<code>react-native<\/code>\u00a0in one remote and forget to align the host, and you don&#8217;t get a build error. You get a runtime crash in production, on a fraction of devices, after the remote has already shipped. Version management is the single hardest part of mobile Module Federation, a point Re.Pack&#8217;s maintainers make from their own experience.<\/p>\n<p>The fix is governance, not cleverness. Treat the host as the source of truth for all shared singletons, pin versions in a shared manifest, and enforce alignment in CI so a mismatched remote can&#8217;t deploy at all.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Native-module-mismatches-and-crash-blast-radius\"><\/span>Native module mismatches and crash blast radius<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A remote that references a native module missing from the host will crash at runtime, because the contract between JS and native is only validated when the code actually runs. We&#8217;ve traced more than one &#8220;works on staging, dies in prod&#8221; incident to exactly this gap.<\/p>\n<p>Two defenses matter here. Bundle the full native surface in the host and have remotes declare native dependencies as host-provided, backed by contract tests. Then contain the blast radius:\u00a0<code>react-native-sandbox<\/code>\u00a0lets you run mini-apps in isolated instances with crash containment and per-module native permissions, so one partner&#8217;s bad release doesn&#8217;t take down checkout.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"New-Architecture-migration-gotchas\"><\/span>New Architecture migration gotchas<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Migrating an existing app to Fabric and TurboModules is not a config flag, especially with a large native dependency tree. Roughly 15% of popular packages still lag on New Architecture support,\u00a0<code>setNativeProps<\/code>\u00a0is gone, several measurement APIs are now synchronous, and\u00a0<code>useLayoutEffect<\/code>\u00a0timing shifts under Fabric (PkgPulse).<\/p>\n<p>Meta&#8217;s own guidance is to start with a feature branch or a smaller internal app before touching production. Profile cold start during the migration too, since assumptions baked around eager native-module loading can regress once TurboModules switch to lazy initialization.<\/p>\n<p>Know More- <a href=\"https:\/\/dianapps.com\/blog\/top-cross-platform-app-development-companies-in-australia\/\">Top 10 Cross-Platform App Development Companies in Australia<\/a><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Flutters-delivery-split-and-review-landmines\"><\/span>Flutter&#8217;s delivery split and review landmines<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If you commit to Flutter and still need on-demand features, you&#8217;ve signed up for a platform-split delivery strategy. Deferred components cover Android; iOS needs a parallel plan, usually bundling the feature or shipping assets through On-Demand Resources.

OTA code push lives in a policy gray zone: interpreted-code updates that don&#8217;t change the app&#8217;s primary purpose are fine, but anything that looks like remotely re-skinning core behavior risks rejection or removal. Govern what OTA is allowed to touch the same way you&#8217;d govern a feature flag with production blast radius.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Shared-state-navigation-and-the-design-system\"><\/span>Shared state, navigation, and the design system<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Across mini-apps, you still need consistent routing, shared auth tokens, and a single design system version.

React Native interprets JavaScript, so JS and asset updates can ship over the air without a store submission. Apple allows downloaded interpreted code provided it doesn&#8217;t change the app&#8217;s primary purpose, so OTA is appropriate for bug fixes and experiments, not for remote-controlling core functionality.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Does-Flutter-support-micro-frontends\"><\/span>Does Flutter support micro-frontends?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Not in the runtime-composition sense. Flutter supports build-time modularity through packages, add-to-app, and Android-only deferred components, but it can&#8217;t load new feature code after release.
