flutter run doesn't show some critical log items from Xcode

Steps to Reproduce

Create an app using Firestore (cloud_firestore in dependencies). For example, the official Firebase for Flutter codelab.
Neglect to set up the iOS project with GoogleService-Info.plist.
flutter run the app on iOS.

This is what flutter run shows, in its entirety:

Similar to #19196.

We're going to use this issue to track improving Xcode output, not the GoogleService-Info.plist issue specifically.

xcrun xcodebuild -workspace Runner.xcworkspace -scheme Runner -resultBundlePath ./output -resultBundleVersion 3
xcrun xcresulttool get --path output --format json

Need to parse ['actions']['_values'][0]['buildResult']['issues'] for warningSummaries and errorSummaries.

xcresulttool-output.txt

See also https://chromium.googlesource.com/chromium/src/+/HEAD/ios/build/bots/scripts/xcode_log_parser.py.

I've been noticing this cluster of issues more recently. Don't know if it's due to an xcode change. The actual error tends to be very unassumingly buried in a wall of text. This likely produces a bunch of red herrings for users. This is a great project to pursue.

The errorSummaries are really lacking for errors coming from dart.

This nice compilation error:
