macOS app fails to build after renaming the flutter_created directory

[HansMuller]

On macOS: if I create an app with flutter create foo and then rename the foo directory, the app fails to run. Summary:

flutter create foo
(cd foo; flutter run --device-id macos) # all is well
mv foo button_examples
(cd button_examples; flutter run --device-id macos) # BUILD fails

See the transcript below for the details. I have a .tar file with the problem app if that's helpful. It's too big to attach to the issue.

The problem goes away upon flutter clean.
