initiated 'flutter run' in VS code and getting the following error:
2020-05-02 16:23:57.827 xcodebuild[97219:3069326] DTDeviceKit: deviceType from 00008030-000D35311160802E was NULL
Any suggestions on what this means?

This worked for me:
rm -rf ~/Library/Developer/Xcode/DerivedData/
rm -rf ~/Library/Caches/CocoaPods/
pod deintegrate
pod update
flutter clean

I ran into the same problem and what resolved it for me, was the following:
- Open YourProjectFolder/ios/Runner.xcworkspace
- Build the Runner project
- Go back to your flutter project and try to run it again
The first build output on the console said
Xcode build failed due to concurrent builds, will retry in 2 seconds
Don't do anything, just wait another minute or two and then it works (for me, at least).
