What I learnt by building the exact same app in Kotlin (Native Android), Nativescript and Flutter
summary
Implements the RealWorld Medium clone three ways: Kotlin native Android, NativeScript-Vue, and Flutter, with code on GitHub. Compares concrete metrics: 3.6 MB Android APK vs iOS ~62 MB, Android app ~1,100 LOC, NativeScript ~230 LOC plus ~100 DTS, Flutter ~470 LOC plus ~270 generated deserialization files. Flutter debug VM raises memory and CPU (peaks roughly double), but hot reload is sub‑second and rock‑solid; NativeScript hot reload and debugging are less reliable; native Android has the most robust breakpoint tooling.
