Cannot find referenced source: packages

Question

I have this pubspec.yaml

    name: Dart Pages
    description: The Dart platform.
    dependencies:
      web_compon         


        

Answer 1

Have you run pub install since you created the "web" directory? If not, try that. You need to have a "packages" directory inside the directory that contains your Dart entrypoint in order for "package:" imports to resolve correctly.

Pub will create those directories for you, but it needs to know to do that. If you add a new directory to your package, you'll want to run pub install again so it add a "packages" directory to it.
