Most teams ask the wrong question. They ask which is better. Nothing is better in the abstract — Flutter and native each win decisively in different situations, and the situation is knowable before you write a line of code.
Here are the four questions we ask on every scoping call, in the order we ask them.
1. How much of your product is platform-specific?
If your app leans hard on widgets, Live Activities, Wear OS complications, deep CarPlay integration or the newest camera APIs, you will spend your Flutter savings writing platform channels. At roughly the point where a third of your surface area needs native code, the cross-platform advantage is gone.
If your app is screens, lists, forms, media playback and a network layer — which describes most apps — Flutter will save you real money.
2. Who maintains it in two years?
A single Flutter codebase can be maintained by one engineer. Two native codebases usually cannot, not well. If your long-term plan is a small team, that arithmetic matters more than any benchmark.
3. What does your performance floor look like?
Flutter's rendering is fast enough for almost everything. The exceptions are real though: heavy real-time video processing, complex 3D, and apps where a 5–8 MB binary size increase is genuinely a problem for your market.
If your users are on low-end Android devices in markets with expensive data, that binary size question is not academic.
4. Where is your existing talent?
A team with two strong Kotlin engineers and no Dart experience should think carefully before committing. Technology choices that fight your team's existing skills rarely pay off, however good the technology is.
Our default
We default to Flutter and argue ourselves out of it. Roughly one project in four ends up native, almost always because of question one. That ratio has been stable for three years.
