Unexpected/surprising behavior due to metrics updates.

matthew-carroll commented 1 year ago

EDIT: I'm updating this ticket after further investigation. I believe I've root caused the issue. I'm leaving my original post down below for reference.

I believe the root cause of this issue is a crossover between two unexpected Flutter behaviors:

The first frame in release mode doesn't know the app's screen size, and therefore builds the widget tree with a size of zero.
ListViews will attempt to build children even when the list has no size.

In the demo code that I linked, the UI happens to start with a ListView that can have infinite children. That ListView is supposed to stop building as soon as it fills the viewport.

The ListView children happen to use AspectRatios, which set the height based on the width. The constraints passed to each list item are (0, 0 < h < infinity), i.e., forcing a width of zero. That zero width, combined with the AspectRatio, forces an overall child size of zero. As a result, the ListView builds children infinitely, because the children have zero size, and they never fill the viewport.

Technically, this could be described as user error. However, this situation is so unexpected, and difficult to track down, that I'm tempted to call this a bug. We spent days trying to figure out what was going on here. I'm not sure what the best alteration would be, but I think something should be done to remove the Flutter footgun in this scenario.

I'm seeing a couple variations of an issue where Flutter UIs never appear. In my team's primary app, we get a white screen that never goes away. In a minimal repro app, we get the Flutter splash screen that never goes away.

Repro steps:

Uninstall any previous version of the given app
flutter clean
flutter pub get
Build and run in RELEASE mode

Flutter version:

Flutter 3.7.9 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 62bd79521d (5 days ago) • 2023-03-30 10:59:36 -0700
Engine • revision ec975089ac
Tools • Dart 2.19.6 • DevTools 2.20.1

For the white screen problem in our main app, we've gotten the problem to repro all the way back into the previous major stable release. But we can't share that code, so we're limited to what's in this ticket.

Test device: Samsung Tab S6

Here's a repository with a minimal Flutter project where this problem happens. There's some Dart code in there that I copied and tore apart from another project. My intuition is that the Dart code isn't relevant.

It's been reported several times that having the Size(0, 0) behaviour only in release mode is a huge footgun:

@matthew-carroll 🤔 This sound like the same issue i've been having recently, but in my case it's on iOS simulator debug mode.

Not sure it's quite the same but this is what happens on my side:

The app launches but it stays on splash screen for about a minute or more
Then I get the window that has the error info below ⬇️
More waiting time passes and...
After doing nothing and touching nothing, the app proceeds to fully launch as expected

Here's the report i got from "Problem Report for runner":

@Juliotati if you think it's the same issue that I described, you can confirm that by checking your layout size in your top level build() method. If it's zero, return a const SizedBox() for that frame. The frame after that will have non-zero size.

If that fixes your issue, then it's the same as mine. If it doesn't fix your issue, then you're probably dealing with something else.

This issue is marked P1 but has had no recent status updates.

The P1 label indicates high-priority issues that are at the top of the work list. This is the highest priority level a bug can have if it isn't affecting a top-tier customer or breaking the build. Bugs marked P1 are generally actively being worked on unless the assignee is dealing with a P0 bug (or another P1 bug). Issues at this level should be resolved in a matter of months and should have monthly updates on GitHub.

Please consider where this bug really falls in our current priorities, and label it or assign it accordingly. This allows people to have a clearer picture of what work is actually planned. Thanks!

The triaged-android label is irrelevant if there is no team-android label or fyi-android label.

Triage: Tried to take a quick stab at rewording the issue title. Following up with the framework folks to get some meaningful logging/error handling.
