.analysis_options

# Specify analysis options.
#
# Until there are meta linter rules, each desired lint must be explicitly enabled.
# See: https://github.com/dart-lang/linter/issues/288

# For a list of lints, see: http://dart-lang.github.io/linter/lints/

#
# This file contains the analysis options used by Flutter editors, such as Atom.
# It is very similar to .analysis_options_flutter_analyze;
# the only difference (currently) is the public_member_api_docs option,
# which triggers too many messages to be used in editors.
