Why my flutter web app does not run upon running webdev serve

问题

enter image description hereI've build my flutter web app and when I run webdev serve
I've got this error message

webdev could not run for this project.
Could not find a file named "pubspec.yaml" in
"C:\Users\Karrar\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\protobuf-0.13.12".

How to fix this problem?

It is answered here https://github.com/flutter/flutter/issues/32313

You have two options:

1. use longer command instead: flutter packages pub global run webdev serve

or

2. add protobuf: ^0.13.11 to your project dependencies and run pub get, this will fetch missing dependency for webdev, then you can remove protobuf from your project
