When Flutter does not save you – Level Up Coding

Flutter (or the other similar Framework “React-Native” ) is only doing its best at UI for single-code development in multi-platform (iOS, Android).

When you need to add on some non-UI features in your apps (eg. customized QR-code, customized foreign language keyboard, etc), you need to develop in native codes (C/C++… ) then called by Flutter / React-Native (Which Choice ? )


Flutter vs React Native vs Xamarin or Native Codes: Which is the best choice for 2019?

Mobile Apps developed for cross-platform : iOS, Android, Web… (Huawei HongMengOS ? )

  1. Flutter (Google) — Dart
  2. Xamarin (Microsoft) — C#
  3. React Native (Facebook) —Javascript


The above analysis for the 3 tools is neutral – beauty is in the eye of the beholder – they are more or less the same family based on current Object-Oriented paradigm.

However, I would recommend a 4th option with additional future-promising Functional Pragramming (FP) paradigm for multi-platform mobile apps:

4. Native Codes in C++ (Version 17) with Standard Template Library.

  • C++ can be developed in Android Studio, called by Java / Kotlin / Flutter via JNI interface.
  • Or in React Native IDE.
  • IEEE 2019 Ranking : C++ / C is ranked 3rd popular language behind Python (1st) & Java (2nd), but it is unique in multi-paradigm & multi-platform, an advantage compared to the others.

The dilemma of maintaining 4 code bases for multi-platfofms:

  1. iOS,
  2. Android,
  3. Windows,
  4. Web.

Key Points:

  • Cross-platform tools for Web / Native codes.
  • Google’s future Android-replacement Fuchsia OS (OO&FP Logic : C++/C, Phone UI: Dart, Web: Rust, Server: Go) Flutter framework for iOS / Android / Windows / Web [Notice: the conspicuous absense of Java]

华为 鸿蒙 Huawei HongMeng‘s answer : “1+8+N” iOT multi-platforms (which will soon obsolete Apple iOS & Google Android)

  1. Smart HD TV (out in August 2019)
  2. Mobile Phones / Notepads (April 2020 Huawei P40)
  3. Driverless Car
  4. PC Desktop
  5. Earphones
  6. AI Sound boxes
  7. Virtual Reality (VR)
  8. Wearables
  9. (+ N) All iOT devices


C++ version 17 (Standard Template Library STL‘ for Functional Programming) is multi-paradigm : Imperative, OO & FP. It curently supports Android as Native codes (ie bypass JVM).
