Flutter performance tips - Flutter in Focus

In this episode of Flutter in Focus, Filip Hracek introduces some basic concepts in Flutter performance. Stay tuned to learn more about what causes jank, why some apps are more battery-hungry than others, and why it pays to keep an eye on memory consumption.

Without flutter I would not have started mobile dev

Please make a boring episode of adapting app for large screens. Say in phone, all settings are in one screen, and clicking on a specific setting takes us to a detail page; but in tablet both settings screen and details screen is side by side.

2:00 I really liked how you skipped video frames to make us feel how bad it is to skip frames in the app. This makes us feel how you guys enjoy your work which leads you to be very smart and creative on presenting it. Good work guys.

Is there a way in the memory analyzer to compare between snapshots so it is easier to spot where the memory leaks are?

[FedJimSmith]

Those slides/animations as well as the person presenting it did a phenomenal job at explaining the topics.. keep it up Flutter Team !!

I tried native and it was messy...I became good in flutter with one week

Dart is worst programming language to learn in 2021. It should be inspired by Python. short line of code, easier to understand, easier to learn.
And Dart is totally opposite.In tech things are getting short and less time consumption but it is worst. It was not expected from Google.

Whenever i look at your videos i remember one of my fav cartoons... scooby dooby :D
Making me nostalgic :)

[darudeSandstorm.]

do you have a github link to the app your showing at the start of the video ?! I cant believe this is running on 60 or close to 60 fps ...

[AlejandroGonzalez-rzml]

0:23 is the source code for that app anywhere public? would like to see it

[kirill]

Hey Filip, thanks for your hard work on Flutter!
Quick question: is there a memory leak if you share BuildContext of your top page?

Thanks!

[bigwig]

add 90 fps option if 120 fps more happy

[SaiyanJin]

The flutter team is doing a great job informing us. That's why it is popular aside that flutter itself is a great tool!

[rahuldange]

Yes we need more videos like this💙. I wished there was medium clap like "like" button on youtube, I would have clapped 50 times :p

[VitorLucasOFICIAL]

Hi Filip, congratulations on the excellent work, as always.
I have a request, could you provide us with the animation code that you showed at 24s in the video?

[Apenschi]

Can I somewhere get the code of the 100-Container-Animation demo at the beginning of the video? Tried somthing similar but get a lot of jank. Thanks!

[pranav-kale]

Well i guess i am catching up a bit late, but thanks for this, it really helped me!

Always great to see Filip. Looking forward to your DevTools video later today for FlutterDay. Thanks for sharing.
