As Realme devices gain popularity both domestically and internationally, developers often face the dilemma of choosing between Flutter, React Native, or native development. The performance differences in UI rendering, resource consumption, and cross-platform maintenance are quite significant. Are there any tools or techniques that can help us maintain a smooth user experience while reducing APK size and power consumption? Feel free to share your practical experiences or reference materials.
In the Realme ecosystem, how should mobile developers balance between choosing cross-platform frameworks, UI adaptation, and performance optimization? What are the pros and cons of different solutions, and do you have any recommendations?

When I started porting our corporate app to the Realme 8 Pro in early 2023, I first tried Flutter for its fast UI development. The shared codebase and built-in widgets helped us build a polished interface in just a couple of weeks. However, I noticed RAM usage spiking to ~350MB on Realme devices, along with minor animation stuttering—especially on models with 4GB RAM. To reduce the load, I offloaded some heavy screens into native modules (Kotlin) via platform channels and added `flutter_image_compress` + `shrinkResources`. This cut the APK size to ~45MB and reduced power consumption by ~15%.
Later, I switched to React Native for a new feature since the team had more JavaScript experience. The biggest win here was faster hot reloading and the ability to reuse web components. Without optimizations, the bundle was around 80MB, and scrolling lists on the Realme 9 Pro caused noticeable glitches. The fix involved `babel-preset-expo` with `enableHermes`, `react-native-screens`, and stripping unused modules via `metro.config.js`. The final size dropped to ~55MB, and FPS stayed consistently above 58.
If raw performance is the priority, native Kotlin/Java development is still the gold standard—direct GPU access and seamless Realme UI integration. But for most business apps, a hybrid approach like "Flutter + some native modules" or "React Native + Hermes + optimized bundle" strikes a good balance between cross-platform flexibility, small footprint, and decent battery efficiency. I’d recommend using Android Studio profilers and `adb shell dumpsys gfxinfo` to track FPS, and `Battery Historian` to analyze power draw on real Realme devices.
