analysis_option_deprecated

Details about the 'analysis_option_deprecated' diagnostic produced by the Dart analyzer.

The option '{0}' is no longer supported.

The analyzer produces this diagnostic when an option in an analysis options file is deprecated.

The following code produces this diagnostic because the top-level key errors is deprecated:

yaml

// %uri="analysis_options.yaml"
errors:
  dead_code: ignore

If a replacement option or format exists, update the file to use it:

yaml

// %uri="analysis_options.yaml"
analyzer:
  errors:
    dead_code: ignore

If no replacement is available, remove the deprecated option.
