I can no longer build my application from the Tools menu "Pub Build - debug" The window alert is:
Unable to run pub
Please select a pubspec.yaml file before running pub.
How does one 'select' a pubspec.yaml file? I have it highlighted in the editor so that's not it. I've restarted the editor and when that didn't work I rebooted. Other pub functions work.
If I open the pubspec.yaml file and click on "run build debug" in the editor it does build. I've not added any imports recently.
Is there a configuration file that might be corrupted?
