Issue: Poor scrolling performance with ListView holding complex widget trees.
Labels: framework,c: performance,f: scrolling,perf: speed,P2,team-framework,triaged-framework

I've made two very complex apps so far, and they both seem to have incredibly poor scrolling performance, even in small list sizes.

My biggest problems with flutter so far have been that there are no guidelines on how to deal with list view performance given a complex widget tree for each child

The first app has a single list view where each child is very complex. The second is a tree of listviews. Every child has a child list view, recursively (its a comment section. almost identical to reddit).

BOTH of these apps have the following behavior:
- Ocassionally smooth scrolling.
- When its not smooth (most of the time), the performance drops even at idle, without scrolling.
- A lot of the time, if I over-scroll to the edge, where the glow overlay appears to indicate the end of the list, the FPS jumps back to 60 FPS. When you take your finger off of the screen, the fps drops again.

This video is recorded in Release mode on my Samsung S9. You can see the particles slow down, indicating FPS drops. The particles are not the source of the slow down.

Based on that list of behavior, I have to assume that the widgets are not getting rebuilt and optimized as much as possible, and there's something Flutter is doing that is causing the FPS to stay dropped even while idle.

The reason I can't share my code easily is that it is far too complicated and intertwined, I'd have to show the entire app for anything to make sense. So in the spirit of good faith, I want this issue to be long-running so that I can get guidance to diagnose the scrolling performance.

Here is the comment class that you see in the video.
https://gist.github.com/6d51d085fc6825698fb03bf00b0d98e3
You can see I'm using ImplicitlyAnimatedListView. I don't want that to be the focus, because in my other app, I use a normal Flutter AnimatedListView with the exact same result.
I know this class is too much code to process, but the main part you should focus on is line 575 `BranchChildren`

It's just a list view of the widget itself, creating a comment chain.
Replacing ImplicitlyAnimatedListView with a normal ListView of course reproduces the exact same results.
