Comparison
The right choice does not depend on framework preference, but on the balance between speed, complexity and long-term maintainability.
Flutter becomes more relevant when you need complex UI components, precise animations or business logic that will evolve. FlutterFlow is often more efficient for standard screens, onboarding flows and CRUD-heavy experiences.
On many projects, I recommend a hybrid approach: FlutterFlow for fast structure and pure Flutter for the modules that are too technical or too critical to stay in a visual builder.
In practice, the best answer is often hybrid: FlutterFlow for fast structure, Flutter for the parts where technical quality becomes decisive.
