deprecated_field

The '{0}' field is no longer used and can be removed.

The analyzer produces this diagnostic when a key is used in a pubspec.yaml file that was deprecated. Unused keys take up space and might imply semantics that are no longer valid.

The following code produces this diagnostic because the author key is no longer being used:

name: example
author: 'Dash'

Remove the deprecated key:

name: example
