removed_lint

'{0}' was removed in Dart '{1}'

The analyzer produces this diagnostic when an analysis options file enables a lint that is no longer supported.

The following code produces this diagnostic because the lint always_declare_return_types is no longer supported:

// %uri="analysis_options.yaml"
linter:
  rules:
    - always_declare_return_types
    - annotate_overrides

Remove the reference to the removed lint rule:

// %uri="analysis_options.yaml"
linter:
  rules:
    - annotate_overrides
