jit compiler produces erroneous runtime optimizations on large applications
TLDR
Amount of classes somehow trigger bugs in runtime jit optimizations, particularly disabling of Inliner fixed the problem for both our internal codebase and generated example.
might be related to https://github.com/dart-lang/sdk/issues/54886
Description
Recently we faced a strange exception, the app would hit it once in a while and stop working till hot or full restart.
example: (actual list of dirty widgets might change)
FlutterError: buildScope missed some dirty elements.
This probably indicates that the dirty list should have been resorted but was not.
The list of dirty elements at the end of the buildScope call was
AnimatedBuilder
#0 BuildOwner.buildScope.<anonymous closure>
#1 BuildOwner.buildScope
#2 WidgetsBinding.drawFrame
#3 RendererBinding._handlePersistentFrameCallback
#4 SchedulerBinding._invokeFrameCallback
#5 SchedulerBinding.handleDrawFrame
#6 SchedulerBinding._handleDrawFrame
#7 _rootRun (dart:async/zone.dart:1398:13)
#8 _CustomZone.run (dart:async/zone.dart:1300:19)
#9 _CustomZone.runGuarded (dart:async/zone.dart:1208:7)
#10 _invoke (dart:ui/hooks.dart:147:10)
#11 PlatformDispatcher._drawFrame (dart:ui/platform_dispatcher.dart:338:5)
#12 _drawFrame (dart:ui/hooks.dart:112:31)
With each passing week, it became easier to reproduce it, to the point when we could not debug full application anymore. So it became clear that size of codebase directly affect reproducibility of this exception.
This idea was confirmed by experiment: removal of usages and imports of any large module extinguished exceptions completely. So imports are enough for reproduction, it doesn't matter if code is actually reachable.
Additional debugging showed that at some point the code in jit mode just started working incorrectly. The idea arose that inlining could somehow influence this and it was it. As soon as I replaced vm:prefer-inline by vm:never-inline behavior of the bug changed, and as soon as I completely disabled inlining the problem vanished.
example of such behavior
dart 2.19.6, flutter 3.7.12 https://drive.google.com/file/d/1AZij0axanL3FNaqV1EMotJJWy65EO020/view
00:08 - animation freezes
00:12 - buildScope exception happen
00:32 - replace vm:prefer-inline by vm:never-inline, and hot reload
01:52 - app is restarted
03:34 - assert _lifecycleState == ElementLifecycle.inactive
04:00 - opening _lifecycleState in debugger, it's actually .inactive, so the assertion is wrong
Steps to reproduce
example with reproduction: example project runtime
-
dart ./tools/generate.dart && flutter run - open and close keyboard a few times, typically 10 times is enough on example that large. expected result: everything continues working actual result: most content of the app is freezed, only focus node still triggers keyboard opening

What have we tried to do to mitigate the issue internally
- Disable inliner: https://github.com/2ZeroSix/sdk/compare/feature/reuse_patch_classes...2ZeroSix:sdk:feature/disable_inliner_for_debug
- the bug was never reproduced with disabled inliner
- Use as few mixins as possible. We couldn't determine why it mitigated the issue so effectively.
I wasn't able to reproduce the problem both on the current Flutter and on 3.16.2.
@2ZeroSix Could you try reproducing the problem on the latest Flutter (main channel) once again? Also, please post the output of flutter doctor -v and flutter run -v of the failing run.
@alexmarkov Sorry, I seem to have messed up the example to the point where it became impossible to reproduce in 3.16.2 and main, while trying to simplify it.
I've just updated it, the only difference is that i moved back a bunch of export directives, didn't expect it to be important. commit: https://github.com/2ZeroSix/flutter_gen_snapshot_oom_example/pull/2/commits/011fdf19293ad87d849d4725fed5c045727f2428
Here are logs from flutter 3.16.2 (dart 3.2.2) and 3.19.0 (dart 3.3.0), but I couldn't reproduce it on main (flutter: 3.20.0-7.0.pre.64 dart: 3.4.0-140.0.dev) anymore.
Can't say whether it's an issue with an example or problem was somehow fixed, because our internal code is not ready yet to be built against newest versions. Currently there is a possibility that it was fixed somewhere between 3.3.0-197.0.dev and 3.4.0-140.0.dev, trying to investigate further.

@2ZeroSix Could you try reproducing the problem with Flutter at b23b3da9353592d6f5d7461ddda13616b00d1815 and 4b110de996eadc4e5080e4725f9d4073a3525914 ?
Flutter b23b3da9353592d6f5d7461ddda13616b00d1815 includes 8c5407b3ddf024dea09aa3db57cbf7c24cca6771 which fixed the bug which appears when there are >64K classes - it could potentially cause the problem you're seeing.
@alexmarkov Seems to be it! Thank you!

couldn't reproduce it on b23b3da9353592d6f5d7461ddda13616b00d1815
I'll try to cherry-pick and try it on our internal code shortly
Thank you, it does really fix the problem that occurs in 3+ versions
The only thing that I still need to figure out is what is triggering "buildScope" variant of exception on 2.19.6, we'll probably stick to work-around with disabled inliner till the end of the migration to 3.0.0
Anyway https://github.com/dart-lang/sdk/commit/8c5407b3ddf024dea09aa3db57cbf7c24cca6771 has not only fixed this problem for versions higher than 3.0.0, but also another one that we haven't been able to report yet!
We were only able to reproduce it in our internal codebase, and we had no luck building an example with the reproduction. All we had is this stack trace: (For future readers: the issue has been fixed in flutter 3.20+)

@alexmarkov it's unlikely, but maybe you know what could have fixed it between 2.19.6 and 3.0.0?
@2ZeroSix thanks for confirming that the fix worked in your app. Can I go ahead and close this issue?

Yes, I have one more question above, but it does have a working work-around and fixed in main.

You don't think https://github.com/dart-lang/sdk/commit/8c5407b3ddf024dea09aa3db57cbf7c24cca6771 fixed that issue?
