Great walkthrough. Makes the tabs (especially memory and performance) in DevTools less "intimidating". Thanks for taking the time and effort to make this!

Would be very useful to many if we could see a deep dive into the Performance tab and how we can use this information to improve app performance - all of Flutter devs should be aiming to build the best performing apps

This is very helpful, I often put slowness widget into my widget tree that slows down the build time, now I can remember to remove them!

Knowing the answer to this question is important for me because I haven't learned any of these tools I mentioned and thinking to make a decision on which framework to use in the long run for developing android apps, iOS apps, web apps, websites, desktop apps.

I would like to know if the subtitles translated into other languages are no longer available. Thank you Flutter team for creating such great learning materials.

Jump to code features does not work in android studio with latest flutter release. Earlier versions works fine

Unfortunately the Network tab doesn't show gRPC requests/responses and my app is totally depends on gRPC. I hope flutter team adds gRPC interceptor to the network tab too.

Great Learning, about performance and apk size etc

You're wrapping expensive widget with repaint boundary instead of progress indicator. I wonder, if it makes a difference of what to move to separate layer expensive widgets or frequently repainted widgets?
