Framework does not handle key events sent by iOS simulator ( Xcode 12.2 ) #68741
Description
Currently it looks like the framework does not handle iOS key events (
). This causes the terminal to fill up with errors when trying to hot reload/restart.An Observatory debugger and profiler on iPhone SE (2nd generation) is available at: http://127.0.0.1:59659/-Rhr2AmeKQM=/

I'm experiencing the same issue
Edit: This is breaking https://github.com/flutter/platform_tests/tree/master/ios_widget_catalog_compare

I can reproduce. Seems like touch handling stopped working altogether on simulator. Even on iOS 13.
gspencergoog commentedon Oct 22, 2020
@xster Touch handling? Or just key events?
gspencergoog commentedon Oct 22, 2020
My suspicion is that because we merged the engine side of this change, but not the framework side (because the tree was then closed), perhaps there were undesired side effects. I haven't tested that hypothesis yet, though.
gspencergoog commentedon Oct 22, 2020
The fix could be as simple as merging the framework side, which I will do anyhow as soon as the tree is open.
xster commentedon Oct 22, 2020
Touch handling is broken as well
gspencergoog commentedon Oct 22, 2020
OK, I'm able to fix the key event problem by just applying the framework side of the changes. I wasn't able to reproduce the touch handling part of the problem, though. Perhaps it's another issue?
gspencergoog commentedon Oct 22, 2020
How are you reproducing the touch handling part of the problem?
xster commentedon Oct 22, 2020
doh! sorry, false alarm from me. It wasn't responding but it was actually that my simulator was frozen :S
I cannot reproduce on master head. Tentatively lowering back to P4.
@DanielEdrisian were you seeing issues with touch handling transmissions in the comparison tool or was it key entries?
