It's not a bug, it's a feature 😂

Please mind that you have to check the checkbox "Track widget rebuilds" on the right-hand side 注意右侧有个 "Track widget rebuilds"，勾选后才开始跟踪组建重建情况 @xiaojielade

I think this panel should open "Track widget rebuilds" by default so it won't make users confused.

@PatrickChoo But "Track widget rebuilds" is also grey. It can't be click

Have you solved this?

The option becomes clickable if you run the app in debug mode.

[jacob314]

Tim is correct. Unfortunately we can only support this feature in debug mode. Leaving this bug open to add a tooltip that makes that clearer.

Is this feature available in attach debug mode?
