Flutter draws every pixel itself instead of borrowing the platform's widgets. That is the whole argument: if your design is the differentiator, this is the stack that renders it identically twice.
What we can show you
One codebase for both stores, and an interface that is identical on each because the framework draws it rather than delegating to the platform.
That rendering model is why Flutter appeals to design-led products: pixel-level control, consistent animation, and a component library that is genuinely shared rather than approximated twice. Dart compiles ahead of time, so performance on scroll and animation is in the range users read as «native».
What you give up is inheritance: platform look, some system behaviours and a few native integrations arrive as work rather than for free. And the hiring pool is smaller than React Native's — a real consideration if you will maintain this in-house.
When the design is the product, when interaction is rich, or when the same interface must also run on desktop. If you already have a React team and a React web product, React Native usually wins on hiring and shared logic — see React Native.

The comparison we get asked for most — including the cases where we recommend React Native and take the smaller project.
Where this stack earns its place in a project, and what we would use instead if it did not.
Brand-specific interfaces, custom motion and components that look the same on both platforms without two implementations.
Charts, canvases, editors and animation-heavy screens where the framework doing its own rendering pays off.
Where the same product also has to run on Windows or macOS from the same codebase.
Submission, review cycles, staged rollouts and crash reporting under your developer accounts — see mobile app development.
The best stack is usually the one your team can maintain after we leave.
Products where the design system is the differentiator, where interaction is rich, and where both stores must look and behave identically.
A team already fluent in React with a React web product to share code with: React Native keeps hiring and logic sharing simpler, and we will recommend it.

The part that is specific to this stack rather than true of every project.
Four things we can prove, not four adjectives.

Tokens, components, states and accessibility semantics first. In Flutter the interface is the architecture, and skipping this step is what makes screen eleven cost more than screen one.

Submission, the review back-and-forth and staged rollouts under your developer accounts — the part first-time founders underestimate.

Because Flutter draws its own widgets, screen-reader semantics and focus order are decisions we make explicitly rather than inherit.

Developer accounts, certificates and repository stay yours from day one, with IP assigned at delivery.
Industries
Flutter goes where the interface is the promise: retail and loyalty apps, field tools for logistics and property, and customer-facing products with a strong brand.
Answered by the people who would do the work, not by a sales team.
Flutter when the design system is the differentiator and both platforms must be identical; React Native when you share hiring and logic with a React web team. We recommend against ourselves when React Native is the better fit.
Technically yes, and we usually advise against it for public pages: search visibility and first load are better served by a web stack. Internal tools are a different conversation.
The framework ships its own rendering engine. It matters on cheap Android devices, so we budget app size explicitly and measure it in CI.
Through platform channels or existing plugins; anything exotic gets a native module, scoped and priced during scoping rather than discovered later.
Yes — tokens, components, states and documentation. Or we implement your designer's system and tell you which parts will be expensive.
Care from $790 a month: OS versions, store policy changes, dependency and framework updates. Flutter releases often, and an unmaintained app drifts quickly.
