# Specify analysis options.
#
# This file is a copy of analysis_options.yaml from flutter repo
# as of 2021-03-19, but with:
# - "always_require_non_null_named_parameters" disabled (because we
# can't import the meta package from the SDK),
# - "avoid_equals_and_hash_code_on_mutable_classes" disabled (same reason),
# - "missing_whitespace_between_adjacent_strings" disabled (too many false
# positives),
# - "sort_constructors_first" disabled (because we have private fake
# constructors),
# - "prefer_final_fields" disabled (because we do weird things with
# private fields, especially on the PlatformDispatcher object),
# - "public_member_api_docs" enabled.
