Flutter Vs React Native [2021] | Which one is FASTER? | Performance and Build size Benchmark

Really awesome

All these is totally unimportant data for real applications! What is important is the actual startup time of the app on a phone on a published app! Users don't give a damn about your build time or whatsoever, they are only concerned about how long it takes for them to see a working app when they launch the app! Developers always forgets that the app is for users, not for some fancy comparison! I hate it when some channel say that this is faster than the other but never mentioned that it is only faster by less and a second! This kind of developer fanboy demo is a waste of time!

Great video thank you bro! However, debug builds that are smaller size means less functionality for troubleshooting and debugging. Not necessarily the winner! Release builds are more important.

Flutter is faster

You are a flutter developer that's why

In year 2021 I go for flutter

Does anyone have experience with both?

You can't compare debug app size because it will not be distributed. You need to compare the release version apk. In my experience release version fat apk of flutter is around 28-30 MB. If you create an android bundle using flutter install size of the app is around 10-13 MB (If an app does not contain lots of assets).
Most important is user experience so you also need to compare how well the app is running on the device. And for that, you also need to use the release or profile version of the app not debug.

React Native app re-run is quick because it does not have to compile just needs to push code to mobile but because flutter needs to compile it takes more time for a re-run. This is a disadvantage of flutter but it pays off because the user experience is much smoother almost like a native app.

React Native has the big issue of when you run the app the first time or you clean build and run the app. If you got lots of libraries and you got large projet it takes 5+ minutes to run some times 10+ minutes as well. But in flutter the difference between small and large app is not that big. Also, the first-run and re-run of flutter app are not that big.

In react native, in my opinion, you should count from the end of the installation, i.e. after npx, which is then what rect native works.

IMO, second build time is not very much important because we have hot reloads once our app is running. so, flutter is again a clear winner there

Completely false information

apk debug size is important? why not evaluate release size?

react native is better from my experience. used both in practice.

Flutter best..and hero

Being around you makes everything better.Good job ...
Team

You are using npx that is downloading react native from web and comparing it with flutter that is already pre downloaded.

flutter always best

Small sample. From the video, we can see that u tried everything once instead of trying multiple times and taking the average of the results.
The test is questionable. You didn't even know why creation run for a second longer in the second try with flutter when you started it alone.
There are no constants in hardware, if u would run it one more time I can guarantee you that the result would be different from the first and second try. Also, you are comparing two different apps you should build one that looks the same using both platforms.
