Flutter for your app? The decision in five questions#
27 October 2026 · updated: 27 October 2026
1. Who uses it — on which device?#
If your users work on the move (drivers, field staff, warehouse, technicians on site), you need an app: camera, offline capability, push notifications, background execution. If everyone works at a desk in the browser, a web application is the leaner answer (web development) — no store, no update cycle, no installation barrier.
2. How many platforms at once?#
That is the core of Flutter: one codebase for iOS, Android, web and desktop. Without Flutter, iOS and Android are usually built twice (Swift and Kotlin) — double development, double maintenance, double feature drift when one side lags. With Flutter, that fork disappears. The more platforms you really need, the more clearly Flutter wins.
3. How close is the app to the hardware?#
Flutter compiles to machine code and does its own rendering — camera, GPS, Bluetooth, sensors and offline storage are first-class citizens. For user-facing mobile work, that is the right foundation. For a pure data table in the browser, it would be a cannon aimed at sparrows.
4. Who will maintain it later?#
A codebase in one language is much easier for a small team — or a successor — to take over than a split of Swift, Kotlin and JavaScript. Handover is part of it: repository, documentation, CI. That is standard with me (process), not an add-on — and it is the part that limits your dependency on the developer.
5. What does the path cost — and what does the detour cost?#
A prototype in Flutter shows on all platforms within four weeks how the app feels (prototype sprint). The detour — native iOS first, Android "to follow" — usually costs more than the supposed saving: double testing, double error sources, and in the worst case a rebuild when the platforms can no longer be reconciled.
When I advise against Flutter#
- Web only, no mobile use: server-rendered web (Jaspr) is usually the better choice then — faster first paint, robust without JavaScript.
- Many SEO-relevant pages: if your application consists of many search-relevant pages, classic web serves you better.
- An existing native team with Swift/Kotlin capacity: switching to Flutter is then an organisational decision, not a technical one — and often isn't carried without a clear benefit.
The short version#
Driver, field and device-facing apps on more than one platform: Flutter. Desk-and-browser applications: server-rendered web. Both in one product: possible — Flutter covers the web as well, and the backend (Serverpod) speaks the same language.
