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!

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

This is 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 🙂
