# Specify analysis options.

# Until there are meta linter rules, each desired lint must be explicitly enabled.

#
# There are three similar analysis options files in the flutter repo:
#   - .analysis_options
#   - .analysis_options_repo (this file)
#   - packages/flutter/lib/analysis_options_user.yaml
#
# This file contains the analysis options used by 'flutter analyze' when analyzing
# the flutter repository. It is very similar to .analysis_options;
# the only difference (currently) is the public_member_api_docs option,
# which is turned on and programmatically reduced to a single output line
# indicating the # of violations for that rule.

  errors:
    # treat missing required parameters as a warning (not a hint)
    missing_required_param: warning

    strong_mode_invalid_field_override: ignore
    # allow type narrowing

    todo: ignore
  # `flutter analyze` (without `--watch`) just ignores directories
  # that contain a .dartignore file, and this file does not have any
  # effect on what files are actually analyzed.
