This will go through the journey of building a blogging app (Medium clone) using Kotlin, Nativescript and Flutter and discuss the differences in developer and user experience for the apps built using all these platforms.
So I took the famous realworld.io project (which is a clone of Medium) and implemented it in Kotlin for native Android, and then using Nativescript-Vue and finally in Flutter.
Although separate platforms, the end result looks identical to the end user.
We will compare a bunch of things across these three platforms -
- Developer Experience
- Performance (out of the box)
- Performance optimisation learning curve
- Memory/CPU/App size differences
- Lines of Code
- Perceptible jank, smoothness
- Constraints and limitations of each framework
- Knowledge of Java/Kotlin for Android development
- An open mind
