Great stuff Gordon, this will help both new and old FlutterDev's. Loved the arrows that pointed to what your were talking about in the code. I somehow got "Robert Brunhage" vibes from this video, lol. The fast pace is cool, but might be just a tiny tad too fast for less experienced Flutter developers, perhaps, hard to say. In any case, great video and topic, keep 'em coming!

First time I hear that someone has a "Robert Brunhage" vibe. I approve 😎

Thanks so much, Mike! Feedback like this is really helpful! The pacing is always hard to get right, it’s definitely difficult to know what will be too fast for a beginner, and non native English speakers. And YES definitely Robert inspired 😅. Stole the arrow from his videos.

@@FunwithFlutter Personally I think the pacing keeps it interesting, definitely not a dull second in the video. As for the “Robert Brunhage” vibe, not sure who is borrowing who’s vibe anymore 😂. You two were always very similar in your tutorials, in an excellent way. Gosh, you even sound a bit alike, tone and tempo wise. I remember in early Flutter days I got you two mixed up when I was trying to recall who had made a video I was looking for 😀💙

@@rydmike The pacing makes the editing process a lot more fun as well! Thanks for all of the feedback and compliments 😊. Robert's vids are excellent so it's nice to hear my vids have a similar vibe.

I love this kind of on point and fast demo

Nice. I really like making them

Great series. Please show using the dart dev tools for profiling an app for cpu and memory and jank. A lot of us have jank problems in our apps but we can not pinpoint them because there are not many resources on using the dart dev tools and profiling. The UI is very complicated. I would love to learn it from your tutorial:D

@FunwithFlutter 3 года назад

Great ideas, thanks. I definitely plan on making vids discussing the dev tools

Loved your way of explaining and showing this! Looking forward to more of these tips 😊

Thanks Robert! I definitely took inspiration from your vids

Going full circle lol

@lucasdelsol1170 2 года назад

Great editing, to the point. Love the fact that you point to the real problem (have pure build) instead of telling people to make everything possible so that build is called less often.

@saibotblack 3 года назад

Great. Please more of this. 👍

@FunwithFlutter 3 года назад

Will do!!

This is veryyyyyyyy related, but no matter how hard I try my flutter apps hardly render under 16m/s...asper I used a ListView builder to render a list of items (clickable items and 10 showed at once on the screen)I previously used a gesture detector and container(only had a text)...it didn't render under 16m/s then I thought and thought I wondered why I didn't use a TextButton...broo!!!!the performance became worse....note all these were in profile mode...like I literally put so much effort in it and they are zero practical tutorials teaches how to make production apps under 16m/s, they always just ranting!!!Cos apparently most people do not care about performance until its visible on the app🙄for God's sake I'm a self taught programmer...show me the way...make us understand how things work underneath and like I don't even know ...just do something about it... please 🙂
