Using GoRouter helps manage app navigation smoothly. It keeps UI transitions fast, aiming for 60 frames per second. Because it uses declarative routing, it reduces unnecessary widget rebuilds, saving memory and CPU. This means less battery drain and a responsive app experience.
To keep navigation smooth, define routes clearly and avoid heavy logic inside route builders. Use lazy loading for screens that are not immediately needed. Also, avoid deep nested navigation stacks to reduce memory use. Test navigation transitions on real devices to ensure no jank or delays.
Adding GoRouter adds a small package size (~100KB). This is minimal compared to the whole app. It does not significantly affect startup time because it initializes quickly. Keep route definitions concise to avoid bloating the app size.
GoRouter works the same on iOS and Android since it is Flutter-based. However, iOS apps require code signing and provisioning profiles for deployment, while Android apps need APK or AAB signing. Navigation animations may slightly differ due to platform conventions, but GoRouter adapts well to both.
Slow screen loading often means heavy work inside the route builder or loading too many widgets at once. Check if you are doing expensive operations during navigation. Also, verify if lazy loading is missing or if the navigation stack is too deep causing memory pressure.
