# Lint headers within paths that contain "/flutter/" but not:
# - gen         (generated code, the fact it compiles is good enough™)
# - third_party (we didn't author most of the code, and can't fix the lints)
#
# Note this is because of our buildroot setup, so the full path of a lint is:
# "../../flutter/impeller/core/runtime_types.h:1:1" as reported.
