missing_name

The 'name' field is required but missing.

The analyzer produces this diagnostic when there's no top-level name key. The name key provides the name of the package, which is required.

The following code produces this diagnostic because the package doesn't have a name:

dependencies:
  meta: ^1.0.2

Add the top-level key name with a value that's the name of the package:

name: example
dependencies:
  meta: ^1.0.2
