The flakes linked here look like issue #189079, platform view tests render a black screen. I recently merged PR #189151 to address this type of failure. That may have reduced the flakiness below 2%, we'll see after another ~50 builds or so. I don't think that PR completely solved the black screen issue, however. Sometimes the app can load in a bad state such that synchronization is not the problem. I have an experimental PR in progress which will detect such a state and attempt a restart.

I'm going to unsuppress this test in the tree so we notice if it starts flaking again. Thanks @andywolff!
Piinks commentedon Jul 27, 2026
Should we close this then if unsuppressed?
andywolff commentedon Aug 3, 2026
It looks like the flakiness level is still above 2%, can we suppress again this until after #190110 is merged? Sorry my first comment didn't make that preference clear
Piinks commentedon Aug 3, 2026
Marked suppressed! FYI - we all with write access have the ability to do so. :)
andywolff commentedon Aug 3, 2026
Ah, thank you, I didn't realize that I could do this. I'll unsuppress and update this issue when I determine it's ready.

My PR has merged and fluttergithubbot says this is down to 1% flakiness anyway, so I've unsuppressed and I'm closing this issue
