analysis_options.yaml

# This file configures the analyzer, which statically analyzes Dart code to
# check for errors, warnings, and lints. See the following for docs:
# https://dart.dev/guides/language/analysis-options
#
# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
# invoked from the command line by running `flutter analyze`.
include: package:very_good_analysis/analysis_options.yaml  # has more lints
