Flutter Europe: Optimizing your Flutter App

Flutter is fast by default, but that doesn't mean you as a developer are off the hook. In this Flutter Europe talk, Filip walks the audience through an app with many performance issues, and tries to address all of them.

I really enjoyed this overview of all the great tools available for us right now

[ResoCoder]

You may not know it yet but 2:20 is what you came here for.

[antobine]

Amazing talk! Very interesting points, hope to see more on this topic

[rebarius]

I like Filip's shirt with the bicycle 👌🏼

[serdarcoskun]

I really enjoyed the video, quite informative. looking forward for new presentations. 👍

Listview scrolling is still laggy for dynamic height items especially in Android. It is affecting the performance

[shashikantdurge]

Nice & Important topic. Looking forward to such advanced important topics ahead.

How does web scrapping work when using the flutter? Using if course the backend what is the best and easiest method in bring that in use?

[tienduy]

thank you!!! The presentation was great >3

[deepaklohmod]

Like you said that if we use stateless widget then all the child of it are considered as a single widget is rendered so is it same for a statefull widget also?

[thisispax]

I would like that 8hr+ workshop please. Even if broken up in separate sessions. 🙇🏻‍♀️

[JoonBeh]

When is the web app going to be released officially? I've been waiting over 1 year.

[pzceonx]

When you fix "Waiting for another flutter command to release the startup lock..." ? When I was able to launch Flutter apps on ios devices during development? It's not possible for now

[Gentleman]

what is the tool filip is using to share phone screen?

[mohamad.elbohsaly]

Should I run profiling on old and new phones? Or not necessarily

[Tomokeneable]

22:00 do I understand correctly then that using statelessWidget instead of method increases performance? So far, I tried to use methods wherever possible and tried to keep one stanelessWidget per page/view. Is this a bad practice?

[andrearsenault]

At 21:25, why is it a performance improvement to break _buildLineWidget() out into a new StatelessWidget? Isn’t Padding (the parent of all 8 children) already a StatelessWidget? Why does wrapping Padding in a custom Widget reduce the number of widgets built?

[lyricsmint]

Flutter needs a beginner series. So newbies can learn from officials.

[YaoBinThen]

Was thinking why everything looks so smooth, then I realized I'm on 2x playback 😂

[mohamad.elbohsaly]

But I wish someone can help in analyzing the graph (jank), so that I can mitigate the sluggishness.
