Flutter hangs when building for iOS #28415
Description
iOS builds sporadically hang at executing xcodebuild -list. This happens so for ~20% builds (every 5th build). We've tried building different iOS apps, reinstall Flutter from a scratch (channel Stable), removing $HOME/.pub-cache
Steps to Reproduce
rm $HOME/.pub-cachegit fetchflutter channel stableflutter upgradecd $HOME/myappflutter build ios --debug --no-codesign -v
