I get this error each time I try to start my app in VsCode
You don't have an extension for debugging YAML. Should we find a YAML extension in the Marketplace?
It was working before I add a font in pubspec.yaml, restarted my app and it didn't work anymore. I tried to restart VsCode, undo my changes, launch "flutter pub get" many times but nothing seems to work.
Click on "open a file", then navigate to the main.dart file and then click debug and run.
