Flutter apk/ipa size vs React Native apk/ipa size

Question

React Native APK size for a hello world example is around 20M (in recent versions) because of support different hardware architectures (ARMv7, ARMv8, X86, etc) while Flutter APK size for same application is around 7M.

What's the reason for the difference in size? Do Flutter support all hardware architecture?

Answer 1

So Junius answer is correct but I don't believe covers the reason why. So Flutter compiles to 100% native code, where RN uses a combination of native code and JavaScript communicating across a bridge.

That is why Flutter does not need to add the JavaScript core thus, the size is smaller. But anyway, as your app grows, the JS part will always be around the same size.
